Hello - first time poster here!
The main floor bathroom in my home is being remodelled. It is smallish (8x8) and will include a tub, toilet and a vanity sink. The toilet and vanity sink will be along one wall with the tub on the opposite wall. The room is being completely gutted. The existing plumbing is being removed and replaced. There is no 'vent' in the old system, but the second floor addition (done 8 years ago) included a new bathrrom with a 3" vent through the roof and at that time I had the plumber include a 2" vent tie-in to that stack in the attic and run the pipe down the access hole to the main floor. The basement below is open (unfinished).
Here is the drawing that I have done showing what the plumber is saying he is going to install. The main stack is 3" and the vent from the toilet and across the top is 2". All other vents a 1 1/2" as are the drains (except the tiolet being 3").
I have had the plumber remove the 90 degree bends that he had originally proposed and replace them with double 45s. The pipes in grey are existing and MAY be left as is (unless they are found to be full of crud - the black lines will be all new. The angled bends with out the connectors are just straight runs of pipe (no bends) but I didn't know how to draw them in a 2D way without the drawing getting too wide and complex.
All drains slope 1/4"+/foot. Does the horizontal vent need to slope too? The vent for the tub actually runs vertically up the tub wall and then takes a 90 turn horizotally to connect to the 2" vent from the toilet/sink beofre connecting to the vertical vent. The blue line is the floor level - everything below will be accessible from the basement after the reno is complete (mostly in the joist space).
Does anything look off or are there improvements that could be made before we start (should we include more cleanouts, etc)?
Thanks.
