Hi,
I'm hoping to get some critique on the attached DWV mock-up I came up with for our new 2nd floor addition before I start tearing into walls.
The fixtures will include two back-to back bathrooms, a washer and a condensing hot water heater.
The mock-up is just the general arrangement. The pipe runs have been shortened to fit in the picture. The 2" horizontal drain will actually be 1 floor down and the 3" main drain will tie into the 4" sewer line in the basement.
The 3" vent will now serve as the main sewer vent to the roof, because this old 1 bath house only had a 2" main vent (and the existing W/C has always gurgled because it didn't have it's own vent!).
My specific questions are:
1. Does this look OK per UPC (Seattle)?
2. Any other clean-outs required?
2. Do I need a trap primer for the HWH drain (The drain is for a Polaris condensing HWH and a hydronic radiant system set-up)?
Any comments will be appreciated. Thanks!
Hazel
