Good evening everyone. I'm a DIYer looking for some experts to take a look at my plan to redo this plumbing in my old farmhouse in WNY. The house was built in the 1880s with balloon framing. In the course of remodeling the property it's time to tackle the plumbing system. We are on a septic system. I'll be utilizing the two roof penetrations (one 3" line to the septic tank with a vent stack and one 2" vent), the septic system will be staying as is, but otherwise the system will be completely rebuilt. Attached is a .pdf detailing the general layout. But as a brief description there will be three full bathrooms two of which will have a washer and dryer (for upstairs/downstairs laundry). On the second floor the master bath and the second floor bath share a wall. The first floor bath is directly under the second floor bath and the kitchen is underneath the master bath. Currently I'm working on the DWV system which is outlined in the file. My chief concerns/questions are as follows:
-The second floor and the first floor will each have a 3" wasteline that the majority of the waste lines will run into. For the individual line connections to the waste line I plan on using a wye fitting to connect the lines to the 3" waste line. I think the waste line should accommodate the flow from the fixtures but do you see any issues with the routing of the line?
-Regarding the venting the dotted lines will run to the other roof penetration vent. However, could I eliminate any of these or do I need to add any given the locations and the presence of the 3" vent stack?
-Is there any issue regarding the waste stack having the sanitary tee basically on top of the wye for the second floor waste line? I would have to alter the floor joists but I potentially could change the sanitary tee / wye into a double wye. Is this needed? Would one ( sanitary tee/wye or double wye) be preferable over the other?
-I plan on putting a cleanout at the base of the stack "under" all of the other fittings. This would place the cleanout in a crawl space with about 2' of clearance, it's accesible but not ideal. Per code could I put this on the first floor where it would be more accesible or does it need to be at the base?
-Regarding the first and second floor clothes washer I was toying with the idea of putting in a drain under the washer with a pan in case of a catastrophic failure of the washer to prevent water damage. I could either go with a pre-made pan or basically build a curb with a shower pan. Is this overkill? If not are there good examples you have seen of the best way to go about putting in this "pan"?
Thank you for your time and expertise.
