Hey, first time poster. I have a barn in the middle of nowhere and inside it I want to build a small
working shop. I'll have a septic tank installed about 50 feet from the building and I'm putting in a slab with in-floor heating. So this will all be under the slab. It's all 3" on the main line there downhill of the red tape. Uphill to the shower drain and the 2 offshoots are 2". The offshoot uphill of the water closet is to a vanity and also a wet vent for the shower. The other offshoot is for a shop sink and a laundry add on later. It will also be a wet vent for the water closet. The red tape is a 5 foot pipe, blue is 2.5 feet and gray is 10 feet.
I read that the water closet drain that I have is ok in some jurisdictions, so I understand if I have to have a separate offshoot so there's nothing uphill of it (That's correct isn't it?). Are the 45 degree little risers I have unnecessary? I wanted to elevate them to not effect the flow of the sewage. Clearly I have a ways to go, just looking for what needs to change based on what I've shown. Thanks
