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.
