You might think with most drainage issues it’s simply a case of phoning your local plumber. You might also think that a drain survey sounds too complex, and expensive, to be worth your while. Can’t the plumber sort it out?
Drainage Expertise
The difficulty with drains is often that while you can see there’s a problem inside your home – a sink that takes ages to drain, for example – the cause of it will be I the drainage network, underneath your property.
So, while your plumber will be fine for replacing pipework and taps inside, or leading into, your property, for serious drainage issues, you need experts in this field.
This is because, to accurately detect and diagnose many drainage issues, requires the right equipment and techniques – those of a drainage contractor rather than a plumber.
One such specialist method at our disposal is the drain survey.
Symptoms, Detection and Diagnosis
You might have smelly drains, or baths and sinks that take a while to empty. These are signs of having blocked drains.
There can also be drainage issues that are not immediately noticeable, but can cause long-term damage to your property, such as a collapsed or leaking drain. This kind of deterioration can, ultimately, undermine your property’s foundations, leading to subsidence.
Collapsed drains can arise from tree root incursion, and this is not something you would necessarily notice.
This is where a drain survey is a vital tool in discovering drainage problems. By sending a CCTV camera down your drainage network and analysing what we’re seeing as it happens, we can get a much clearer picture of the state of your drains, revealing damaged areas or blockages.
Your drains may require re-lining, or even replacing. A drain survey will give us the information we need to get a clear idea of the action we need to take to sort your drains out.
This is not something your plumber can do.
If you suspect you have any of the symptoms of a blocked or damaged drain, get the experts in. Contact us today.

Water pollution is a serious issue, whether it’s chemicals from factories or the pollution caused by domestic consumers and misconnections of household appliances.
If misconnections happen, then foul waste may be discharged into a surface water network. This can then cause serious pollution.
One of the ways of revealing misconnections and diagnosing cross-contamination is by drain tracing.
The Risks of Cross Contamination
From the 1920s onwards, the UK water industry has worked to keep foul waste water and storm or surface water systems separate.
This is to ensure that sewage treatment plants are not having to deal with large amounts of rainwater on top of the considerable volumes of foul waste water.
Storm water should reach soak-aways, or rivers, while foul waste goes into sewage treatment.
However, where there are misconnections, foul waste may find its way into the storm water system, with a consequent pollution threat to rivers.
This pollution can be from faecal waste, but also chemicals from washing machine detergents.
Risk and Responsibility
Surveys of residential areas have found significant percentages of appliances misconnected, meaning they were emptying directly into rivers and streams.
Often this is not deliberately malicious, but arises from people not understanding the sewage system.
It may be that, for example, a washing machine kept in the garage has been connected to the nearest outlet, but that this may in fact be a storm drain, and not meant for waste water.
There are also plumbing innovations, such as saniflo, that allow for a toilet to be fitted pretty much anywhere. However, it must still be connected correctly so that it discharges into the foul water system.
There are consequences: the homeowner is responsible. There can also be problems if you misconnect a storm or surface outlet to the sewer, leading to the sewer flooding.
Remedial Action
The temptation is simply to connect to the nearest available drain – this often occurs with new builds and extensions.
If this is the case, it may not be immediately obvious that there has been a misconnection.
This is where drain tracing comes in. Sonar technology allows us to use sound to build up an accurate picture of a drainage network.
If you are the owner of a property, you must be sure your drains are connected properly, and legally.
We can make sure you know, and take the right action to resolve any misconnections leading to cross-contamination.

Make no mistake: for many water companies, disposable wipes are the enemy. Disposable wipes are essentially an evolution of baby wipes, designed to appeal to the adult market.
One of their chief appeals is their disposability. However, in 2016, UK water firms wrote to the Chartered Trading Standards Institute (CTSI) urging it to investigate the issue of wet wipes clogging up the nation’s drains.
In many cases, a CCTV drain survey is essential to discover the cause, and location, of the blockage.
Water companies want manufacturers of moist toilet tissues and other non-biodegradable wipes to clearly and prominently label them as not flushable.
Consequences of Wet Wipes
Because many moist wipes are not paper-based, like standard toilet tissue, they are not dissolvable. They may also, over time, release plastics into the environment, with long-term consequences for the human food-chain.
Some urban drainage systems are quite resilient, but many are old, some even Victorian, and are therefore not equipped to deal with this kind of waste.
One danger of having some wipes labelled as disposable, whether they really are or not, is that it leads to the assumption that most, if not all, wipes are.
This further clogs up the drainage system.
Water companies feel it would be more environmentally responsible to remove flushable from all packaging of these products, to avoid consumers making the wrong assumptions about them.
Water companies in the UK spend around £88 million annually clearing drains, and estimate that half of these blockages are avoidable.
The Diagnosis for Drains
While water companies may feel that disposable moist wipes should be a national issue, it is often at the local level where the impact is felt.
If you are experiencing issues with your drainage, whether you’re a commercial concern, or it’s your home, then you may have long-term drainage issue that cannot simply be shifted.
This is where a CCTV drain survey is essential. This allows us to see what’s going on in the inside of your drainage network, and whether you have damaged or blocked drains.
It forms the basis for a comprehensive drainage report, up to date plans, and a recommended course of action to sort your drains out.
Disposability may feel convenient, but the consequences for drains are serious.
If your drains are in need of attention, please contact Drainage Consultants for a CCTV drain survey.
