So far so good. No signs or sounds of any water backing up or siphoning back into the washer. Will keep an eye on and post if awl heck (sorry ladies) breaks loose. If there is a backup problem, I'll look at drilling a hole in the plastic adapter and running a 1/4-in copper tube outside thru the wall.

Here's a photo of the connection to the drain pipe.

Has anyone else had this problem?

"Guv Bob" wrote in message news My washer has a pump that is too strong for the drains in this old house. From what I have heard, some kind of tight connection is OK as long as the washer has a pumped drain and not a gravity type.

Being an expert seat of the pants, shade tree type feller, I thought I better pass this by the pros here before I throw the switch.

I already rooted out the drain all the way to the sewer, and the roof vent is clear. Still not quite big enough for the newer washer.

Sketch of what I'm think about doing:
