All,
I have a kitchen sink upstairs which is directly vented out the roof. I added a utility sink and washing machine drain in the basement sharing the same drain pipe. I recently failed a plumbing inspection because my city follows the UPC and does not allow studor valves. I also had used a sanitary tee to tie the sink / washing machine drain into the drainpipe which I found is not allowed. Anyhow - I am replacing the sanitary tee with a double outlet tee (I was told this is UPC compliant). I am also properly venting. Unfortunately I have a couple of questions and the inspector has not returned my calls.
Venting:
I will be venting the washer and utility sink up to over 6" above the kitchen sink water line and tying it back into the main vent. I am assuming both basement fixture drains can share this vent as long as I tie them together in a manner that always follows 45 degrees or more to vertical and tie into the main vent as specified above. Is this correct? As far as where these originate I have heard conflicing statements regarding critical distance for a 2" drain under the UPC - can anyone confirm this measurement for me?
Pressure Testing:
I was originally told that because of the small amount of work I was doing a pressure test would not be required. The scope expanded and I now must perform one. Under my double outlet tee I have a cleanout fitting. Is this sufficient to plug with a baloon for pressure testing or should I have a true 'test tee' in my configuration?
Thanks in advance all for any advice!
