Hi All,
I am planning a bathroom remodel that I plan on doing mostly by myself. I will say up front I am good at DYI but know my limits and will not bypass permits and work required by licensed contractors. You get burned once and you never do it again. Having said that, before I agree to my wife's desire to relocate/replace a tub with a shower, I want to understand feasibility of doing so. The house was built in the 60's and the current 1st floor bathtub has a drum trap attached to 2" cast iron draining back to the main stack. The drum trap in the basement sticks well below the floor joists and I have always hated its look and intrusion being so low, but it was tolerable since it was only 2 ft out from the basement foundation wall. see pic 1 for current plumbing.
Going to a new location pushes the drain further away from the basement wall. The new drain will be 2" PVC with p-trap and the trap to vent distance is still within 5'. However, the 1/4" per foot slope and my desired height is putting the trap weir well above the current vent opening , so I need to vent it differently. I would prefer not use an AA valve, although if my plumbing inspector allows, it could be a simpler resolution. There is a vent for the washing machine that starts in the basement and ties in further up the stack. the kitchen sink adjacent to the bathroom also uses this vent. The vent turns horizontal into the stack well above the new shower floor. This seems a likely choice, but where I would prefer it to go vertical for the vent and drain into the existing stack opening is just loaded with 'stuff' : supply lines, gas line, heat pipes. See pic #2
As an alternate I would go vertical closer to the trap. See pic #3. Do you guys see any problems from your end with pulling off this relocate?
Thanks
