Why Is There Water Under My Drain Cover?
If you have lifted a drain cover and found dirty water sitting underneath, as shown in the image, you may be wondering whether this is normal or a sign of a blocked drain.
A small amount of water can sometimes be present in parts of a drainage system, but standing water that is not draining away properly can indicate a blockage or another drainage problem. The important thing is not to ignore it, particularly if you have also noticed slow drainage, unpleasant smells or water backing up around your property.
At RM Drainage and Plumbing, we help homeowners and businesses with drainage problems throughout Rayleigh and Essex, using professional equipment to identify the cause and find the right solution.
What does standing water under a drain cover mean?
If water is sitting inside an external drain or inspection chamber, there could be a restriction further along the drainage system.
A blockage may prevent wastewater or rainwater from flowing away as it should. Depending on where the obstruction is located, water can begin to collect in the chamber.
The image accompanying this article shows an external drain chamber with dirty standing water and a noticeable build-up of debris. While a photograph cannot confirm the exact cause, this type of condition is a good reason to have the drainage system checked, particularly if water is not clearing naturally.
If you have discovered standing water under a drain cover in Rayleigh, RM Drainage and Plumbing can investigate the problem and advise on the most appropriate solution.
What causes a blocked drain in Rayleigh?
There are many possible causes of blocked drains in Rayleigh and across Essex. Some blockages develop gradually as materials build up inside the pipework, while others can occur suddenly.
Common causes include:
- Fat, oil and grease entering drainage systems
- Wet wipes and other unsuitable items being flushed
- Leaves, mud and garden debris entering external drains
- Tree roots growing into damaged or ageing pipes
- Cracked or collapsed sections of underground pipework
- Build-up of dirt and other waste inside the drainage system
External drains can be particularly vulnerable to leaves and garden debris, especially when material is washed towards gullies and drainage points.
RM Drainage and Plumbing regularly deals with blocked drains caused by a range of issues, including grease, tree roots, damaged pipes and debris.
What are the signs of a blocked external drain?
Standing water is not the only warning sign to look out for.
You may have a blocked or partially blocked drain if you notice:
Water draining slowly
If sinks, baths or other fixtures are taking longer than usual to empty, there could be a restriction somewhere within the drainage system.
Unpleasant smells
Bad odours around an outside drain or manhole can indicate stagnant water or a build-up of waste.
Gurgling sounds
Gurgling from toilets, sinks or pipes can sometimes occur when air is struggling to move through restricted pipework.
Water backing up
If water rises inside an external drain when you use a sink, toilet or washing machine, this can be a strong indication that the drainage system is struggling to carry wastewater away.
Repeated blockages
If you have already had the drain cleared but the same problem keeps returning, simply removing the immediate blockage may not be enough. There could be an underlying issue with the pipework.
These are all reasons to arrange a professional inspection rather than continually trying to clear the problem yourself.
Can you unblock an outside drain yourself?
For a very minor blockage that is easily accessible, some homeowners may be able to remove visible debris. However, you should be cautious when lifting drain covers or attempting to clear deeper blockages.
Avoid putting your hands into standing water, particularly when you do not know what the water contains. You should also avoid using harsh chemicals in an attempt to resolve a significant external blockage.
If the blockage is further down the pipe, drain rods or other DIY methods may not solve the underlying problem.
A professional drainage engineer has access to specialist equipment that can be used to locate and clear stubborn blockages safely.
When is a CCTV drain survey needed?
If a drain keeps blocking, there may be a problem that cannot be identified simply by looking into the chamber.
A CCTV drain survey in Rayleigh uses a specialist camera to inspect the inside of underground pipework. This can help identify problems such as blockages, cracked pipes, collapsed sections, tree root intrusion and damaged joints.
This can be particularly useful when a blockage keeps returning. Instead of repeatedly treating the symptom, a CCTV inspection can help establish what is actually happening inside the drainage system.
