I have a dilemma with my washing machine and could use a quick fix. It seems my waste line (1 1/2″) is not large enough to accommodate the water draining from the washer. The waste line fills up and overflows before the washer completes draining. Big problem, slab floors keep me from changing to a larger waste line size. A plumber friend of mine suggested changing the trap from 1 1/2″ to a 2″ to handle more volume. Tried it… didn’t work. Any other suggestions?

I've had the same problem in my house and what I did was seal the the washer drain to the house drain, but the only problem is depending on the type washing machine, you may have to install an anti-siphon valve at the connection between the washer drain hose and your plumbing. The(anti-siphon valve) should be available at any appliance parts store. But first I'd try it without the valve and see if it works. That's my two cents and you can keep the change
*Most newer installations are required 2" but many, many are 1-1/2" (including my own) and not posing a problem. Have you rodded out existing all the way to main waste junction? Some thoughts. Randy
*A couple of "redneck" solutions come to mind, though they aren't very good ones.Put a bigger pulley on the pump so it turns slower. Then it should pump water slower and not overwhelm the drain. Don't have any idea how hard that would be, though. Put a pair of vise grips on the hose, and clamp it part way closed to slow down the water coming out. (That's i definitelyredneck)O.K., maybe one practical solution - How about putting in a laundry tub, and dumping the washer into it? Then it would act as a sort of "buffer" to hold the water until it could drain away.
*Boss Hog,Your idea is good not only to deal with the high volume of most washing machine pumps, but also to allow filtering of the drain water before it goes into the house's plumbing. Anyone who's put a filter sock over a washing machine drain hose would appreciate this. Biggest problem for "Dirty Laundry" could be inadequate space for a tub.
*Boss: Those aren't Redneck solutions - neither included duct tape or WD-40! The use of visegrips is close, however.Don
*Any other fixtures on that 1 1/2 drain line? If so, can they be rerouted to another drain line.Where that Wethead Warrior? There are code issues here, but that depends on when the house was built and where.
*soap buildup is a problemrod it out or use a chemical drain cleanertry a restriction (smaller outlet) on the hose to slow the water dischargeuse of an extra part qualifies as hi tech, compared to redneck ideas like a c clamp.
*Thanks for the input. I picked up a ball valve, 2 1/2" plastic nipples and a hose clamp. The restriction idea was a good one, and it worked like a champ. Guess I'll have to add a "redneck" classification to my contractors license.
