Washer Drain Help Needed
 
I've already had my entire laundry room and hallway rebuilt due to this issue happening previously. However, when rebuilding, I had the contractors atleast cock the wall area near the drain pipe so that water would not seep down into the wall. Good thing too. As I now see my washer has decided once again to drain the water during the spin cycle and then bubble up from the drain pipe. If I turn off the washer, the water sucks down into the drain pipe. Seems to have good suction. So, if I turn the washer off and on, it will drain but obviously, I need this fixed as I can't sit there and watch every load of laundry drain. If I run the water hose down the drain pipe at full blast, it drains fine. It does not bubble up. Plumbers could not find anything wrong with the main line. Now they are suggesting putting in a cleanout for the trap. Expensive but is it necessary. Could it be the washer is draining too fast? It is 9 years old but working fine. I've even replaced the drain hose. But still it bubbles up and attempts to overflow into my laundry room when hitting the spin cycle and draining. Perhaps the vent on the top of my house has gotten full of leaves, etc.? Is it o.k. to run a hose down this vent? I haven't snaked the line yet, I'm leaving that for last. I have put a liquid draino product that was safe but it did nothing. Anyway, any help would be appreciated. I'm not sure what to do next.

is your sewer system by chance on septic? Clogged fields will cause slow draining, and wash machine is pumping out lots of water at one time. If you have city sewer, I would think there has to be a blockage somewhere down stream from the washer. And yes, I've run the garden hose down the roof vent looking for blockage before, no problem.

City sewer, not septic. Plumbers have checked the lines and everything checks out o.k. The only thing they have not checked is the P Trap. So, my guess is that its the trap. But I just don't see how that would get clogged up so easily or that often. Especially after not having problems for 9 years or so. I'll try running the hose down the roof vent and snaking the trap. Not much else I can do I guess? One thing I do notice is that the vent is a bit off center from the wash room due to the roof line. Any other suggestions are appreciated. Thanks.

I'd try from inside first rather then chance falling off the roof, the washer can spit out alot of lint, it may of caked up in the trap, not sure if you feel comfortable cutting out the trap to replace with a new one w/cleanout, in my case my trap is buried in the wall, but anyway, a couple things I would try first, you can try wrapping a towel around the hose where it enters the drain pipe, try letting the washer pressure clear out the line, be sure to have one hand near the off button in case of too much pressure, another idea to put the garden hose down pipe, with water turned on, let the metal tip of the hose scrape along the trap, hopefully loosening the clog to push down stream. They make a rubber bladder that attaches to the hose, just not sure for that size pipe. I feel for your troubles, not knowing if your going to have a flood is very nerve wracking, good luck

I'm not sure where you live, but here we have code that specifically governs the installation of clotheswasher trap and standpipe.

Trap must be minimum of 6" above the rough floor.
Clotheswasher standpipe must be no less than 18" from the trap inlet, and no more than 30"

I wonder if perhaps your standpipe is too short? I've not seen this predicament yet in my travels, but I am just throwing out ideas.

I also wonder about your vent. I've seen some places where a DIY'er plumbed their vents on the inlet side of the traps, which is basically just as bad as not having a vent at all... this might create gurgling and slow draining, even though the lines are not clogged ?
