Hi hope that someone from this excellent group can help with this one..
It's sure got me scratching my head.
We have a main-floor laundry room with a sink in our two story home.
The washer drains into a pipe that joins the sink drain prior to the p-
trap. Every week or so we've noticed an awful smell in the laudry
room, which I suspect is a sewage odour, as if the p-trap has lost
it's prime. If I run water down the drain the smell eventually goes
away.
I've checked under the p-trap but can't find any water there and don't
think the joint is leaking. It's as if something is sucking the water
out of the trap, but have never heard of this before.
The house is located in the greater Toronto area in Canada. The street
has a gentle slope to the south. We have an apartment in the basement
of the house, with a full kitchen and bathroom. The second floor has 2
bathrooms, but nothing directly over the laundry room.
We've taken to just leaving the stopper in the sink as a temporary
measure, but obviously would like to resolve this problem.
Thanks for all replies.

Thanks Moe. That link was very helpful.
I don't think that there is anything else draining into the line that
this laundry sink drains to. All the other water lines are on the far
side of the house... and the sink drains well, so I suspect the vent
is ok. I'll have a look though. There is too much water running from
the laundry there ( 6 of us living in this house and using that one
clothes washer) for the trap to ever dry out.

* If there are strings hanging over the weir of the the trap (from the
washing machine) the water will capillary out. *Leave a wet towel
hanging over a full sink and you will see how it works. *Also self
siphoning which is how a toilet works, but toilets have a refill tube
that tops them off after every flush. *It's hard to do but a trap can
flush its self almost dry if the velocity of the water is enough.
* Google drain waste vent system and you will find lots of information.
* What it all amounts to is getting water to stay in the trap, I suspect
you might need a ventless vent and it has to be installed correctly to
work.https://www.centraltrailer.com/cart/...=product_info&...

know to be a plumber,
1. The boss is a SOB
2. Sh*t runs downhill
3. Payday is Friday at five
