Drain Smells Wolverhampton
Drain smells are often the first indication that your drainage system is not working as it should. A build up of waste which causes a temporary smell then flushes away is probably nothing to worry about, but if you are noticing a bad smell in the house over a prolonged period it needs investigating. Is the smell noticeable only at certain times of the day or after the drain hasn’t been used for some time?
What causes drain smells ?
Drain odours are a common plumbing problem, they have a number of different causes but they aren’t always difficult to fix. Probably the most common cause is a collection of waste in the underground drainage system in other words a blockage or part blockage causing gasses to travel up the line to the house. Under normal usage conditions drain odours are blocked by your P trap, a 180 degree bend in your drain line which traps water to prevent odours passing through. Loss of trap seal (evaporation of water in the trap) in little used facilities is also very common. If the water seal evaporates drain smells can pass into the building.
Usually evaporation of trap seal takes several days, the easiest way to fix this problem is to simply turn the tap on to refill the P-trap. If the drain is a sink drain, run the water for about 10-15 seconds. If it’s a shower problem allow it to run for about a minute. Loss of trap seal is rare for toilets but can be solved with a simple flush. If it’s a recurring problem you’ve probably got a blockage.
Has it been several days since you last used a particular drain? Whether it’s in your bathroom, kitchen, or a utility room drain, any drain with a connection to your sewer line can cause foul odours if the trap seal is lost. A more serious cause would be a structural defect like a cracked pipe allowing foul gasses to enter the building, this would need to be found with a CCTV drain survey.
Another common cause of drain smells is tree root ingress causing poor flow and blockages. Roots in drains cause stagnant areas which ideal areas for drain smells.
How do you investigate drain smells ?
The starting point is a site visit to see where your drains run and have a look inside the property so that you can explain where and when the smell is noticeable. During the same site visit this is usually followed by a CCTV drain survey which enables us to see the inside of the drainage system.
Can the smell be caused by a plumbing problem ?
Yes, common problems we see are missing ring seals, loose joints, pipes not falling correctly, lack of venting and faulty air admittance valves.
How do you stop drain smells ?
How we stop the smell depends on what is causing it, the drainage system may need cleaning or clearing by jetting, very often this solves the problem. There may be a drain repair needed such as a cracked pipe which needs replacing or relining. There could be a valve that needs to be replaced or a pipe that needs refitting so that it falls correctly.
How does drain jetting help with drain smells ?
Drain jetting previously known as hydro jetting was developed in the 1950s for the very purpose of cleaning large diameter pipes. Its the best, quickest and most thorough way to clean drains and get rid of drain smells. The nozzle propels itself along the drain pipe, using water pressure around 3000psi cleaning the pipe as it goes. Its eco-friendly using water only, no chemicals required.
