Hey all,
On to the 2nd floor plumbing. Attached is the plan and isometric. The laundry and bath share the plumbing wall. Please let me know what you think. Also a few questions..
-I may not do the floor drain for the washer and just add a washer tray with a 1" drain line to the exterior (no trap and no invasive work to the 100 year old hardwood floor). Is this fine for any potential flood problems with the 2nd floor washer or would you advise the floor drain? If so, what size? The washer pan would be the simplest and least invasive. I also plan to add an emergency cut off at the supplies.
-Is this 3" waste enough for the bath and laundry? It is only for the 2nd floor. It will tie into the 4" that drains the first floor bathrooms. I'm guessing its only about 12 DFU's total so I think I'm fine
-The 3" through the roof vent is venting everything here plus the downstairs bath and 1/2 bath. This is about 25 total DFU's so I think I'm ok
-I plan on putting the cast iron back for the main stack to help reduce noise. I may even do the Quiet House idea https://www.charlottepipe.com/quiet_house.aspx. It uses CI of all drains and PVC for vents
-My hybrid DWV plan is to use CI for all drains that I don't want to hear noise, solid core PVC for all drains that are more isolated and foam core PVC for all venting. I ran this by inspections and they were OK.
Thanks again!!
