smelly washer?

[jammydodger]

help! my washing machine keeps smelling of drains. the waste connection has a trap but the pipe terminates right at the bottom of the stack pipe. is there a certain height that the last waste connection has to terminate into the stack pipe. i also keep getting black lines on my clothes. any help would be greatly appreciated thanx

Do you mean the washing machine is tee'd in after the trap. If so then that would be why you're getting a smell. It should be connected before the trap as the water in the trap is what stops smells coming up from the drains.

no the washer is correctly piped with its own trap

stagnant wter in the machine,
buy some lemon deodoriser from shop.

Maybe induced siphonage from the stack. A positive zone in your soil pipe at the lowest point where the air is compressed. If it's identified as such then anti-siphon can be fitted

Run the machine on a boil wash with some detol in it.

is there a certain height that the last waste connection has to terminate into the stack pipe.

Yes. 450mm from the invert of the stack to entry of connection. If it's a long radial. Make sure the w/m waste is secured above the drum too.If it's not then the water from the waste hose is becoming stagnant.
