Have a 1.5" drain and new washer overflows it. I took the trap off and the metal pipe. It's full of some debris inside. My plan is to snake it and flush then use a 1.5-2" adapter at the T in the wall, then 2" p trap and 2" pipe. Anyone else drain a new speed queen into 1.5? Worried I'll do all of this and it will still pump too fast. It's going into my laundry tub now. Not sure what would be involved in changing out the drain through the slab but might not be worth it.

Was your previous washer draining ok?

Yes, 4 year old Maytag bravos. The drain tube on the Maytag is much smaller. The pump on the speed queen is a beast though.

It could have been but those speed queens can push some water. Hopefully it will work after just some cleaning. 1.5” sounds small for a drain.

I know this used to be standard for washers. Not sure the chances there's a reducer in the wall. I'm no plumber. Here's the drain to the wall. Not sure what that vertical piece is, if it's part of the fitting or not or trash. Havent dug in there yet.

Is the drain pipe old cast iron?

It's metal, I haven't looked too close. The elbow on it was. Maybe at the slab it's 2"? If that's the case I could probably do it myself. Not sure what standard sizes are through the slab. 1.5 would be odd. House built early 70s

That does not look ideal

I'm hoping there's a 2" pipe under that 1.5" tee. Still debating whether to cut the call and look.

We had that problem too. I cut the load size back to just above medium and it drained ok. We have a very old sewer line and had roots at that time. It's just my wife and I here so we run it like that no problem. I love my Speed Queen washer. 7 years in and zero problems.

Mine does not offer load size. Maybe normal delicate modes.

I would rent a small electric drain snake w a 3/8” cable and clean out that pipe. The corrosion and crud build up is reducing your flow by probably 50-75%. You may need a jetter to clean it out good. You can get a jetter that attached to a pressure washer from amazon

I have a drill snake and a bladder I can hook to the hose I can wedge in the pipe and try to flush it. If that doesn't seem to make an improvement I'll get the water jet kit. Looked the other day at them. Or I cut the wall and see if there is a 2" pipe in there and it's reduced. Guess I should try to flush it first and try with what I have.

Try bending the end of your drill snake at a 20 degree angle so it scrapes the inside of the pipe instead of punching a 1/4” hole in any clogs when the snake is straight at the end

Another approach to solve your problem [if the drain line is too small] is to reduce the flow of water coming out.

Modify the line coming out by putting a reducing coupling or maybe a valve to restrict the flow water. Yes, this will take a few minutes longer to do a load of clothes, but much cheaper than replacing an under sized drain line.

Is water overflowing, or is it sudsy bubbles?

Will try this if needed.

I read about this problem but it really is too much water volume for now. Draining in the sink I can see the sudsy bubbles people talk about. Won't have time to work on it until the weekend.

I'd be weary of putting any back-pressure on the pump.

Ideally, you should have about 2' of vertical pipe inside the wall with a trap right above the slab. That riser gives enough room for the water to get out of there before it starts to over flow. If theres a tee looking out the wall with a P trap like it sounds like you're saying, the best bet would be to open that wall up and install like I'm saying.

Look up pictures of a washing machine box installed for a better idea. Typical new install will be a tee ~7.5" above the ground. The top of the tee goes up as your vent. The bull or middle of the tee goes out to a p trap that then goes up in the wall to meet a box at around 36" above finished floor. And it's always 2".

Start small, you can rent a sewer machine or pay someone and see if that works. If not, your most permanent fix is like I said above. A jetter will work on soft clogs but it will not break the scale/corrosion of the inside of the pipe and you probably have a good bit of that inside of a 50+ year old pipe.
