That is the lowest open point in the drainage system of the home. Anything that goes down the sinks also backs up into the bathtub, again because it's the lowest open point in the system. We have thawed out about 10 sewers this year. Normally only 1 or 2 but with the really cold temps it has gotten colder under the homes. You can crawl under your place and tap on the pipe with the plastic handle of a screwdriver. A solid, frozen, pvc pipe sounds noticeably different from an empty one. If you have any cleanouts on the system you can open those also to have a look, just be careful cause if it's not frozen at that point you will get wet!!
You would think though the hot water from the washer would slowly melt the ice away.
I think i'll try some hot water in the drain as soon as the bleach smell settles & see if that does the trick.
Hop it won't explode though mixing the bleach with the hot water.
At least it will melt away my stools faster.
They can collect in the drain in large clods I suspect.
I do know a drain pipe will freeze faster than the main water lines under house.
I have 2-1/2 inch thick insulated panels with styrofoam in between them surrounding my home.
Never have problems with water pipes freezing.
Thanks for that info!
