Mystery Smell, Well Horrendous Stink Actually.

[tsteve9999 456]

Does the smell appear when you have the central heating on? If so it's definately a dead mouse. After eating poison they look for somewhere warm to lie up and it's usually next to a central heating pipe. You wouldn't believe the smell that can come from a tiny mouse thats next to one, and it will take a couple of weeks for it to dry out and the smell to disappear. If not another possibility that I came across once was that the sewers may be backing up when it rains a lot, and if you have a soil pipe under a concrete floor that is not sealed completely it can force foul air out through it and cause the entire room to stink.

Have you got sufficient drainage alongside your extension?.We were getting intermittent smells near our back window in the living room,and at times the smell was horrendous.It got that bad i dreaded a knock on the door because of the smell.After a couple of years of tradesmen taking a look etc we finally took a brick out of the wall.The rain had been collecting under the house for god knows how long and it had to be drained out.

To combat this we had french drains put in that made no difference at all,and i got sick of seeing muppet tradesmen scratching their heads.Its not smelled for several months now but when it does im getting the enviromental health involved.

I can t believe they now know the problem,and the council have done nothing apart from spending as little money as possible in a vain attempt to sort it.

Check that there's an air break in the grey pipe from the back of the washing machine. That U shaped guide that most people discard needs to be fitted and needs to be as close to the underside of the worktop as possible. This is a common cause of smells. I doubt you've got syphonage issues unless your house is 4 storeys or taller. Don't tape up the standpipe serving the washing machine or any other openings within the system because you'll create air locks and the waste water won't run away properly. A trap that is filled with water will prevent smells without the need for any tape or cloths blocking the open pipes.

Cheers again folks,

 

Personally leaning towards a washing machine related issue Myself.

 

Hoping it's not drains as they were all new, and the fact that it's only now and again that's confusing me. Doesn't tie in with when washing machine is on / off, either tho.????

if its only happening every few weeks then tell the mrs not to be leaving the moon pants lying around as it smells worse than portavogie harbour on a catch day in a summer heatwave lol oj

If the washing machine isn't installed correctly you will get intermittent smells depending on the rate of syphonage or backflow from the waste and or machine.

If your sure its not through lack of use, then check how washing machine connects to waste pipe. Then it will be suction, if you fill a sink then pull a plug does the other sink gurgle ,when washing machine is pumping do sinks gurgle,it might need to be a combination to empty if it's not happing often,ie washing machine emptying same time as sink emptying.

You could be on to something there.. If they're all tied into the same waste, something like flushing the chain on the toilet could be emptying a trap or traps somewhere along the system.

 

You could fit an air admittance valve somewhere in the system to stop it happening, I've seen them used on jobs before. Not being a plumber, I couldn't say where would be the right place to put one though!

Come across it a few times if the pipe work cannot easily be changed I generally change the trap that's getting siphoned , for a hep trap,it doesn't need water to seal.but the air admittance valve would work.
