Washing machine stand pipe smell

Duvetdays

Hi all,

There is an unbearable stink of drains in my kitchen for the last while and I wasn’t too sure where it was coming from (smells like it’s everywhere)

I think now it’s coming from under the sink / back of washing machine. The machine is right beside the sink. Googling today brought up the possibility that the spin cycle vibration may have pushed the drain hose into the stand pipe too far past the trap allowing smells in. At the weekend I removed the hose and cleaned the gunk that was on it from inside the pipe I’ve also had soda crystals and bleach down the stand pipe trying to flush out the smell. There’s a good chance I too pushed drain hose past the trap inadvertently when I put it back in as smell hasn’t gone.

So my question is can I cut a piece off the end of the hose as it seems far to long sagging at the back of the machine and secondly how far should I have the hose sitting in the stand pipe?

Any advice on this is greatly appreciated!

Its hard to imagine the pipe extending so far that its interfering with the trap if its of the U bend type?.

The washing machine hose normally comes fitted with a hard plastic attachment (at least my two have) about 4 to 5 ins long that tapers down and has a ~ 1 ins hole at the end for the waste water, it is just stuck into the stand pipe and because of the taper it will only extend ~ 3 ins into the stand pipe, it just sticks inside the stand pipe but because it has raided ribs on it has a clearance all round to allow the waste water to flow downwards by gravity only.

You may have some other problem with your main/waste pipe, is the vent pipe that extends up to the roof line clear?, it could be blocked with moss/weeds at the top.

Many thanks for the help.
When I pulled the drain hose from the stand pipe there was over a foot length of it in the pipe. I now have it the there’s only about 4 inches of it going into the pipe but now that leaves a lot of lag with the hose behind the machine. The vent pipe isn’t near the kitchen and no other room smells bar it.

I’ve flushed out drains with a hose in case of blockages between them and next step is to lift the manhole to the sewer although there’s no smell in the back garden so I doubt the main drain is the cause.
