Could a washing machine drain be too short in length?

Back up a yr ago...noticed water coming into our living floor with Off of a wall shared with our laundry room. Sure enough, washing machine drain was over flowing. Move the washig machine from the wall, find out that sheet rock (no wet rock) was screwed, went ahead and knocked it out for fear of mold (we're remodeling the house currently). Plumber ran snake through roof vent, but I wasnt sold that was the fix all problem, so I put a quart size Tupperware bowl under the pea trap on the drain.

FF today, notice water from from of the washer, no where else, not a lot. Sure enough, move washer find Tupperware full.

Could it be that my drain isn't long or large enough to hold the amount of water the machine is draining off?

Edit: I know I'm a DA for not just going ahead with fixing and remodeling the room then

Is your drain one of those wall mounts where the drain hose kind of just sits in the hole loosely? Water can back up and come out of the drain on these. They make a silicone ring you can put in the drain hole and the drain hose fits more snug. But your stand pipe that your drain hose fits into needs to also be minimum 18" tall and the taller the better.

What size is the P trap? You should have a 2” trap on the wash machine drain. I’ve seen 1.5” in the past and it is not adequate for the amount of water pumped by your machine.

Can you not watch it OP? Most drains are visible, or you can at least move the machine to where you can watch it. Run a load and watch it, see what happens.

Yes you could have a blockage, your drain could be too small, or your hose not long enough to where it’s splashing back out.

How far down the drain does your washer hose go?

Just 1.5"

move the washer


Herein lies a issue. Previous owners mounted a folding table above the plumbing. Also, the plumbing is actually mounted behind the dryer. So I assume the drain hose is not in there very far

I’d move the washer box behind the wash machine at this time-increasing it’s size to 2” while in the process. Between moving the box and increasing its size, your problem should go away.

to start off, the plumber is an idiot if he snaked the vent, the issue is the main line has a restriction causing the backup. snaking the vent just justifies time spent he can bill you for instead of using that same time to snake the actual drain line to clear the blockage
