We are adding a washing machine hook up on our 2nd floor. We would like to make the hook up as shown in the attached drawing. The washer drain hose would be tightly connected to PVC pipe, with the vent rising directly after this connection, and the p-trap following immediately. After the p-trap the pipe will go 7 feet and join the main soil stack, which, of course, has a vent. We were told that 7 ft is too long for a washing machine drain line to travel to vent, which is why we are putting in the additional vent. However, we are a little bit confused as we have read that a the vent should always be AFTER the p-trap, but our proposed setup (vent before trap) would be much easier to fit in our given space.
What to do you think? Is this a reasonable set up?
Thanks for your help!!
