There are several effective methods of drain cleaning, and the best method depends on the severity and nature of the clog. Here are some commonly used methods:

1. Plunging: Plungers can be highly effective for clearing simple blockages in sinks, toilets, or showers. Create a seal around the drain opening with the plunger and vigorously push and pull to create suction that dislodges the clog.

2. Drain snakes or augers: These tools are useful for reaching deeper clogs. Insert the snake into the drain and rotate it to break up or retrieve the obstruction.

3. Baking soda and vinegar: This natural solution can help dissolve minor blockages caused by organic matter. Pour half a cup of baking soda down the drain, followed by half a cup of vinegar. Let it fizz for about 15 minutes before flushing with hot water.

4. Enzyme-based cleaners: These cleaners contain bacteria or enzymes that break down organic matter in drains over time, helping to prevent build-up and keep drains flowing smoothly.

5. Hydro-jetting: This method involves using high-pressure water jets to clear stubborn blockages or remove accumulated debris from pipes effectively. It is typically performed by professionals due to its specialized equipment requirements.

6. Professional drain cleaning services: If home remedies don’t work or if you have persistent or severe clogs, contacting professional drainage companies is recommended. They have access to advanced tools like hydro-jetters, CCTV cameras for inspections, and expertise in diagnosing and resolving complex drainage issues.

The choice of method depends on factors such as accessibility, severity of blockage, personal preference, and available resources. It’s important to use caution when attempting DIY methods and seek professional assistance if needed.

What is drain cleaning acid and is it safe?

Drain cleaning acids are chemical substances designed to dissolve or break down tough clogs, such as hair, grease, or mineral deposits in drains. One common type of drain cleaning acid is sulfuric acid.

While drain cleaning acids can be effective at removing certain types of blockages, they also come with potential risks and safety concerns. Here’s what you need to know:

1. Safety precautions: Drain cleaning acids are highly corrosive and can cause severe burns if they come into contact with the skin or eyes. It is crucial to wear protective gear like gloves and goggles when handling these chemicals.

2. Toxic fumes: Acidic cleaners can produce strong and potentially harmful fumes that should not be inhaled. Adequate ventilation is essential during use.

3. Pipe damage: Some types of pipes, such as PVC (polyvinyl chloride), rubber, or older metal pipes, may be vulnerable to damage from acidic cleaners. Prolonged exposure or improper use of drain cleaning acids can lead to pipe corrosion or weakening over time.

4. Environmental impact: The disposal of drain cleaning acids must be done responsibly following local regulations since they can harm the environment if not handled properly.

Given the risks involved with using drain cleaning acids, it’s generally recommended to explore alternative methods first, such as plunging, snaking, or using natural solutions like baking soda and vinegar. If these methods prove ineffective for stubborn clogs, it’s strongly advisable to seek professional help from experienced drainage experts who have access to safer yet powerful commercial-grade products specifically formulated for drain clearing.

What is a drain cleaning air gun and what is it used for?

A drain cleaning air gun, also known as a drain blaster or drain plunger gun, is a tool used for clearing clogs in drains and pipes. It operates on the principle of compressed air to create pressure and dislodge blockages. Here’s what you need to know about drain cleaning air guns:

1. How it works: A drain cleaning air gun consists of a handheld device with a trigger mechanism and a rubber or plastic attachment that fits over the drain opening. When the trigger is pressed, it releases a burst of compressed air into the pipe.

2. Creating pressure: The sudden release of compressed air creates high-pressure force inside the pipe, which can help push or blast away obstructions such as hair, debris, or minor clogs.

3. Versatility: Drain cleaning air guns are typically used for smaller household drains like sinks, showers, or toilets. They may not be suitable for larger drains or more severe blockages that require professional intervention.

4. Safety precautions: While using an air gun may seem straightforward, it’s important to follow safety guidelines provided by the manufacturer. Wear protective eyewear and ensure proper ventilation when operating these devices.

5. Limitations: Drain cleaning air guns are generally effective for simple clogs caused by organic matter but may not be as effective against solid objects or stubborn blockages deep within the plumbing system.

It’s worth noting that while drain cleaning air guns can provide temporary relief from minor clogs, persistent or severe blockages may require professional assistance to properly diagnose and resolve underlying issues.

Drain cleaning and camera inspection

Drain cleaning and camera inspection are two essential services offered by drainage companies to diagnose and resolve issues in drains and sewer lines. Here’s what you need to know about each:

1. Drain Cleaning: Drain cleaning involves the removal of blockages, debris, or build-up that can impede the flow of water through drains. It is typically done using various methods such as plunging, snaking (using drain augers), hydro-jetting (high-pressure water jets), or chemical cleaners. Drainage CCTV Drain Inspection derby

The goal of drain cleaning is to restore proper drainage by clearing clogs caused by hair, grease, soap scum, food particles, or other materials that accumulate over time. Regular drain cleaning maintenance helps prevent blockages and maintain optimal performance.

2. Camera Inspection: Camera inspection involves using a small waterproof camera attached to a flexible cable that is inserted into the drain or sewer line. The camera provides real-time video footage of the interior of the pipes, allowing professionals to visually inspect their condition.

Camera inspections are useful for identifying various issues such as cracks, leaks, tree root intrusions, pipe misalignments, corrosion, or other structural defects within the drainage system. This visual assessment helps determine the appropriate course of action for repairs or replacements.

By combining drain cleaning with camera inspection services when necessary, drainage companies can accurately identify underlying problems causing recurring blockages or poor drainage performance. This enables them to provide targeted solutions tailored to specific issues in order to ensure effective and long-lasting results.

It’s important to note that both drain cleaning and camera inspection services are best performed by trained professionals who have the expertise and specialized equipment required for accurate diagnosis and safe execution.

CCTV Drain Survey

What is a CCTV Drain Survey?

Recent infrastructure studies underline the general deterioration of sewer systems and the risk to public health, the environment and increasing costs (ASCE, 2009). Since the origin of sewer systems in the 19th century, sewers have been installed in different
periods using available standards and technologies. Sewer assets have a limited service life and it is crucial to assess their condition throughout their life cycles to avoid potential catastrophic failure and expensive emergency rehabilitation due to their deterioration
(Hao et al., 2011).

This report first presents the wide panel of inspection technologies available to obtain information about sewer defects and conditions. Visual inspection (e.g. Closed-circuit television CCTV Drain Survey equipment, zoom cameras) appears to be the industry standard for sewer inspection. It provides visual data (images and/or videos) of the internal surface of the pipe. Defects are usually coded manually by the inspection technician according to standard coding methods.

CCTV Drain Survey


In Europe, the current codification system is the normative EN 13508-2 for visual inspection (EN 13508-2, 2011) used by the CEN-Members (European Committee for Standardisation). In addition, physical techniques are available that can give further
information and details about pipe defects.

These techniques do not replace the CCTV drain survey inspection but can give deeper insights into the type and severity of defects. Sonar and Lasers enable you to analyze pipe geometry and can identify defects such as deflections, cracks, sediments or corrosion. Ultrasonic testing and magnetic flux leakage (MFL) are applied directly to the pipe wall. They enable you to measure wall thickness and detect pipe
defects such as corrosion, deflections and cracks. Ground Penetrating Radar (GPR) and Infrared Thermography are used from above ground and are useful to locate pipes and identify bedding conditions, voids and leaks. Finally, network-wide inspection technologies like smoke testing or Distributed Temperature Sensing (DTS) can locate cross-connections and/or sewer infiltration. The purpose, inspection procedure and limitations of these methodologies are briefly presented.

In a second stage, this report presents the available classification methodologies developed to interpret automatically visual CCTV inspection reports and evaluate sewer conditions. These methodologies enable to transfer of the extensive amount of visual inspection data from CCTV drain survey inspection into a more easily manageable number, useful to support asset management practices. Most approaches have a similar goal: they aim to rank rehabilitation priorities and support municipalities in the definition of rehabilitation
programs. They do not pretend to replace the knowledge and analysis skills of a local expert but can help him or her to identify rehabilitation priorities.

All methodologies provide an overall condition score for each sewer segment or sub-scores for different requirements (e.g. structural and operational conditions) or dysfunctions. From the review of available methodologies, two main approaches can be distinguished: priority-based and substance-based methodologies. For priority-based methodologies, the calculation of sewer condition grades is based on the most severe defects, the density of defects and/or the length of the defect.

Condition grades express the priority of rehabilitation, i.e. the emergency of action regarding the probability of failure or collapse. For substance-based methodologies, the final score is calculated based on the length of sewer that will be affected by rehabilitation actions. Substance based methodologies do not aim to assess the condition of sewers but rather to rank sewer pipes considering the amount and type of rehabilitation needs: replacement, renovation and repair.

Each methodology aggregates and combines sewer defects in a very different way making very hazardous the benchmarking of final scores from different methods. Therefore, municipalities using different evaluation systems are not able to benchmark the condition of their networks. Finally, the accuracy of the classification results remains a key issue, crucial for the further use of inspection data to support asset management strategies.

Asset management is an increasing concern for wastewater utilities and municipalities. According to a need survey conducted by EPA (2008), the total funding needed for replacement, rehabilitation and expansion of existing collection systems for a 20 year period in the USA is 82.7 billion dollars, i.e. 28% of the total need of public agencies for wastewater treatment and collection. According to a French ministerial survey (OIEau, 2003), the total need in France for sewer rehabilitation is about 7 billion euros. Average yearly investments in the wastewater system in France are about 1.7 billion euros (including capital costs for replacement, rehabilitation or expansion of existing collection systems). In Germany, a national study estimates that about 17% of the sewers have severe defects and should be immediately or in short term rehabilitated (Berger and Falk, 2009).

In the last 30 years, most municipalities have invested in sewer system expansion and treatment plant upgrades but a relatively small
amount has been allocated to the improvement of sewer system conditions. Part of the funds needed to upgrade the condition of sewer systems will be generated through increases in municipal taxes and user fees (Allouche et al., 2002). Other efforts will focus on the reduction of overall costs through the definition of cost-effective rehabilitation plans and the optimization of inspection and maintenance programs.

In this context, the condition assessment of sewers aims to evaluate the current condition of assets and support the prioritization of maintenance and rehabilitation activities. The assessment of sewer condition is crucial in implementing a successful asset management program since the cost of sewer failure may have significant economic impacts on the municipality or utility (Rahman and Vanier, 2004).

Most condition assessment methodologies aim to provide an overall grade to each inspected sewer, which represents the current condition of the asset. Input data to these classification methods are sewer defects recorded during CCTV inspections and coded according to standard coding systems. For that purpose, mobile and rotatable cameras are inserted into the sewer system to record pictures or movies from the inner side of sewer pipes. Damages, defects and other abnormalities are documented and additionally described using standard defect codes.

Besides CCTV drain survey inspection, a number of additional inspection technologies are available. They can be used complementary to CCTV to gain more precise information about sewer defects or to identify defects hardly visible using inspection cameras such as
deteriorated bedding conditions.

Pipe cleaning is used to clean and maintain pipelines. The wastewater conveyed in the pipes can cause deposits and eventually partial blockage. Gurgling or bad odours in the drain are often the first signs that the pipe cross-section has reduced and can cause smelly drains outside.

Depending on the application and pipe material, there are the following methods for pipe cleaning:

Pipe Flushing Derby

The simplest cleaning method is pipe flushing. Special nozzles are used here, which remove the deposits from the pipe wall using high water pressure. Most loose deposits are removed simply by increasing the flow rate.

Chemical Pipe Cleaning

Chemical pipe cleaning is the use of chemicals to remove deposits. A typical example is the removal of a blockage using a pipe cleaner. However, this type of pipe cleaning pollutes the environment and is therefore not used by us.

Mechanical Pipe Cleaning

We use mechanical pipe cleaning. Pipe cleaning spirals are moved through the pipe to remove deposits on the pipe wall. Depending on the type of deposit, a suitable attachment is used, such as milling head, root cutter or chain knocker. We can get rid of your smelly outside drain problem quickly and economically, call us for a quote and advice.

Preventive Pipe Cleaning

In the case of commercially used sewage pipes, such as in the catering industry, grease deposits inevitably lead to a reduction in the pipe cross-section. Once the pipe is completely clogged, flooding and water damage are often the result during operating hours and, in the worst case, can even lead to loss of earnings.

This can be prevented by regular preventive pipe cleaning. Of course, the recommended frequency of preventative drain cleaning varies from business to business. Call us for advice on this.

In gastronomic establishments, the drain pipes in the kitchen are mostly affected, since the grease that mixes with the wastewater when washing up and cleaning the floor settles again on the inner walls of the drain pipes within a short time.

However, clogging of the drain pipes of urinals, caused by the formation of so-called urine scale, can also become a problem, as this can be very difficult to remove after a few years. Pipe cleaning should be carried out here every 4 to 5 years.

CCTV Drainage Survey

CCTV Drainage Survey

Do you need a CCTV Drainage Survey and if so what does it involve?

As drainage problems are not always visible a CCTV Drainage Survey will deliver an extensive review and identify any major or minor issues. A camera drain survey will direct and locate the issue which may include blockages, cracks or any kind of structural damage. A survey can also identify issues caused by tree roots, displaced pipes and joints, badly installed drains, signs of wear and tear, corrosion and rodent infestations. The CCTV unit has a transmitter that sends images and data back to a monitor so that your plumber can identify the location of the problem.

CCTV Drainage Survey

A closed-circuit television camera will be inserted into the relevant drain in order to review the damage. The use of flexible rods can navigate bends or corners as the cameras can self-right this means that any rotation or twisting caused by the rods can be corrected.

A CCTV Drainage Survey can take up to three hours for an average three-bedroomed house though before surveys are carried out it is usual that high pressure jetting is carried out which can take up to one hour. This is carried out because a pipe may contain debris and material such as stones, tree roots, fat, oils and grease or silt. If these are not removed first the CCTV camera may not be able to travel through the pipe or record unobstructed images of the pipe which will need to be reviewed to assess the condition of the pipe.

Before purchasing a property a pre-purchase drain survey could save you money on the asking price of the property and also help you get a more competitive mortgage deal as there is less risk which could result in you paying less on your mortgage repayments. A CCTV Drainage Survey will show if there is subsidence to environmental damage. Should you purchase a house with poor drainage you could end up spending money on upgrades and improvements and eventually you could be looking at foundation problems and water damage.

How do you know if you have drainage problems?

  • Cracks in the foundations
  • Gushing gutters
  • Deposits and flaking on the walls
  • Migrating mulch
  • Mildew in the attic
  • Water stains in the basement
  • Downspouts that dump

Full CCTV Drainage Surveys

The gathering of data helps the client to plan for urgent pipe repairs, rehabilitation or to support a planned preventative maintenance (PPM) programme:

This would include:

  • A map of the drainage system showing main lines and lateral connections, plus manholes and surface water drains
  • Lengths of pipes
  • Pipe falls – this is a measurement of the gradient along the pipe
  • Flow rates and flow directions along the pipes
  • Location of pipe defects supported by HD-quality video

Other techniques used during a CCTV Drainage Survey are:

  • GPS surveys
  • 3D mapping
  • Topographical surveys

Will house insurance cover blocked drains?

When purchasing your insurance policy check that it covers damage to underground pipes, cables, drains and underground services. Insurers will not cover problems with pipes owned by companies, neighbours or water companies even if the issues arise from them. CCTV Drainage Survey

CCTV Drainage Mapping

CCTV Drainage Surveys help to map the drainage and sewer systems. This should detail drain water flow direction, manholes and drain runs. Drain mapping can help find out where the boundaries lie, who has responsibility for the infrastructure and pinpoint any drainage pipes or sewage ahead of building work.

Before starting any building work it is important to know where nearby drains and sewers are and who has responsibility for them. It is the responsibility of the property owner to inspect the drainage infrastructure before any building work or property extension is to commence.  Drain maps may be required to determine whether a ‘build over’ agreement is required.

What to expect from a CCTV Drainage Survey:

A CCTV Drain Survey Contractor should have the expertise and equipment to carry out the relevant survey. They should also:

  • Assess drains have the relevant equipment used to complete the process
  • Investigate the drains using CCTV using live feed and relevant software systems so survey reports can be provided in a timely manner with the correct data to suit the client’s needs.
  • Have access to data gathering services, such as 3D mapping and topographic surveys
  • Live feed should be uploaded to show the areas requiring repairs or others such as sewer cleaning
  • Provide advice on services to resolve any drainage problems found

Fat Leads to Sewage Flood

Previously on our blog we’ve looked at just how much of an issue fat can be for drains, and the danger – yes, danger – posed by delicious English fry-ups. But we couldn’t help but feel sorry for residents of Witney, in Oxfordshire, after their high street was flooded with sewage last Thursday.

It all started around 9am, precisely as shops begin opening and shoppers flock to spend their hard-earned moolah. That was when waste began spewing out from beneath a drain cover outside of the Co-Op store and the local opticians, Scrivens. They weren’t the only shops affected though, with others also having to deal with the eruption of waste that spread. And until the cavalry arrived, shops had to use brooms to sweep away up to a centimetre of waste from their premises. Outside of the Methodist Church, the highways agency erected a battalion of sandbags to stem the tide of flow.

Manager of Scrivens, Jennifer Blackie, said: ‘When we left work on Tuesday, we could see some water around the drain, but it was clear, so we didn’t think anything of it. But this morning, it was all over the pavement and it was brown and full of loo roll and everything else. Customers had to walk in it to get into my shop.’

Ms. Blackie reckons that the drain in question bursts at least once a year, for the past seven years. That, she claims, is simply ‘not acceptable.’

And what’s the blame for the barrage of sewage that affected Witney? Our old arch-nemesis, fat, of course. According to Thames Water, who were sent to sort the issue out, one of the tributary drains, which feeds into the main drain under the high street, had become blocked. Thames Water explained: ‘A fat blockage in our sewer pipe led to five properties suffering sewer flooding.’

Down Your Toilet: Things You Should Never Flush Down Your Toilet

Baby wipes, paper towels, nappies – these are just amongst a large number of things that people flush down their toilets daily, without realising that they could be causing a lot of problems to their drains.

A blocked drain can be extremely inconvenient, especially for those who are too busy to wait around for someone to come and fix it. So why risk causing a clog in your drain?

As a company who specialises in providing solutions for drainage issues, including blocked drains Sheffield residents rely on, we have seen an awful lot of things that have been accidently, or purposely, flushed down the toilet, that really shouldn’t have been.

It’s become clear to us as professionals, that many people simply do not know what should and shouldn’t be flushed. For that reason, we have put together a list of all the things that you should avoid flushing.

Hands on yellow gloves cleaning a WC

  1. Dental Floss

With dental floss being so small, a lot people mistakenly think that they can flush it down the toilet. This is a mistake as floss isn’t biodegradable, and can cause a lot of problems when there has been quite a lot of it flushed together. It will wrap itself around other objects in your pipeline, and any minor clogs will soon become bigger ones.

You should just put it straight into your bin!

  1. Paper Towel/Kitchen Roll

Paper towel and kitchen roll are both larger and thicker than your average piece of toilet roll, and there is no easier way of finding this out but when attempting to flush it down your toilet.

They don’t break down in the same way as toilet roll and will cause a massive blockage in your drains.

  1. Cat Litter

We can see why a lot of people would think it was okay to put their cats waste down their toilet – it’s just a little bit of urine right? Unfortunately, cat litter contains clay and sand, which are two things that should never be flushed.

And what many people don’t know is that cat waste contains toxins and parasites that are dangerous to be in your drain system! So when you are cleaning your kitty’s litter train, put it in the bin or properly recycle it.

  1. Medication

Clogs aren’t the main issue when flushing medication – it’s the damage it can do to our water supply that is the problem.

You may feel like you are doing the right thing by flushing unwanted medication down the toilet, so that it can’t get into the hands of unwanted people. However, it can cause a lot of problems – contamination of groundwater supplies and terrible effects on wildlife downstream. Sewage systems don’t remove medication, therefore they get released straight into rivers, lakes and oceans.

Your local pharmacy will be able to dispose of them in a better way for you.

Other things you shouldn’t flush include:

  • Hair
  • Tampons/Pads
  • Grease/Oil/Fat
  • Band Aids
  • Cigarette buts
  • Cotton wool/Balls

Basically, all you should be flushing down the toilet is everything created by your body’s digestive system and toilet paper. Everything else should just be disposed of in a different, environmentally friendly way.

If you have drainage problems and you’re looking for an affordable solution – we have got you covered.

Here at Inspect-A-Drain, we are drainage experts with years of experience in providing solutions for blocked drains. So if you need help with your drains, we recommend contacting us for professional help.
