Washing Machine / Kitchen sink smell

[PeteBoyle]

Hi all

I am looking for some advice; I am new to all this, so please take that into account if I do not explain myself very well.

I have recently had my kitchen redone; a number of challenges have occurred along the way; not least a smell of eggs coming out of the kitchen when the washing machine is on.

I have attached picture to explain the current configuration; I wanted your opinions on whether or not this set-up is correct?

The grey pipe with yellow end (told you I was not technical!) is the drain from the washing machine...the main U-bend is plumbed in under the smaller of the two sinks above (previously, the u-bend was under the main sink above). The smaller pipe behind is the condensing pipe from the boiler, but cant see this causing issues. Am I correct in thinking the smell occurs because: A) gunk that goes down main sink plug can easily travel down the washing pipe as it is set up. B) the current set up is before the u-bend, so the trap of water doesn't benefit us when the washing machine is on. C) The pipe from the washing machine should be higher and flow down to the connecting pipes (in essence to stop situation A from happening?

Any advice is gratefully received. Builder is coming round this week to 'discuss' this and other problems. He essentially subbed out the work to somebody else...which in my opinion is immoral...EG I'm paying for you, you do the work...this may be a little naive of me though

I have attempted to run a hot (90) wash, which helped a small amount, but not a great deal.

Blocked pipe from wm?

I think you have hit it on the head A+C try loosening plastic connector where discharge pipe connects
and swing pipe upwards retighten connector to create pipe falling rather than rising.If not possible
then re-route pipe so that it does fall rather than rise,hope this helps.

Washing machine hose shouldn't be facing down should loop up of trap to stop sink waste heading down w/m hose , m'y guess is hose is to short

Thanks everyone, good advice all round.

The pipes are all clean; either new or cleaned by myself when I removed from old kitchen, before placing in new kitchen.

The drain pipe from the w/m isn't long enough, so will try to reroute or see if I can buy an 'extension' of some sort to allow gravity to work its magic.

Thanks again all.

Hi Pete,

I have a similar problem with the lovely smell of egg in my kitchen which I'm playing with at the moment. I think mine is due to a loop-de-loop dishwasher waste pipe before it hits the main waste discharge pipework. I just need to get the bother to sort it out.

Point A and C, once you do as you say, should benefit you and get rid of the smell. I reckon it's just a collection of stagnant water in the w/m waste pipe. And because of point B, it's allowing the smells through your plug. Once you raise the w/m waste pipe and give it a fall, you'll have no more water retention in that pipe = no smell.

Scarily though, in my set up the landlord thought it was a good idea to have a 3-way plug box to plug in the w/m and d/w and leave it sitting directly underneath the waste pipes. Should there ever be a leak, I'll be sure to touch something metal!

i can see 2 grey pipes? i would have run the w/m into a seperate trap as to me it looks like the w/m water will sit between the trap and "will call it an access blank"

But if there's a slight fall where the w/m connects and the trap, a second trap isn't required as the water will drain naturally?

yeh but surely the fowl water could potentially sit in the trap causing a dodgy smell through the other sink?

Only if the sink isn't used at all, letting the water stagnate. But I assume their taps are used regularly enough to keep the water in the trap fresh.

fair comment, i would be inclined to disconnect w/m and leave for 24hrs and see what happens with smell mate

Bet it smells in wm as well. Dirty dish water running into wm. Sort out the hose as said previously.

Drop the Washington machine hose down to the trap the trap gunge wont run up the pipe to go into Washing machine
