I am installing a clothes washer as part of a bathroom remodel and want to connect it to a drywell that is technically illegal in MA but allowed since it is preexisting, and grandfathered in. The problem is that the drain pipe in the basement that goes to the dry well is 1 1/2 in. I know that 2" is code for washers, but since this will not be inspected, do you think that it will drain OK? I am assuming that it will cause the previous owner used it. I located the well and it is only about 6 ft from the outside of the foundation so the run is short. Washer will be a small stackable front loader.
