I am wondering what my options are for...

    Minimum distance of wet vent to furnace vent

    I can't find any information on how close a plumbing vent (PVC) can be to a metal furnace vent. Reading through my local county code website I can't find any specific information either.

    Is this plumbing plan to code?

    Does anyone know if this plumbing plan is code? Can I tie in the shower drain plumbing into the existing sink drain plumbing with these fittings or do I have to take the shower plumbing directly to the main pipe? I would tie it into the main stack but I'm running out of room because this is the...

    How many bends can be in a tub drain?

    Im getting ready to run the drain for my basement bathroom but I'm concerned that I have too many turns in the tub drain. I had to start in the wrong direction in order to pick up a wall for a vent. Is this a problem, does it meet code? A second set of eyes on this would really be appreciated.

    Plumbing question with our residential basement remodel

    My plumber says the height of the drain from the kitchen above is correct. Maybe I’m over-thinking the height but I think it should be 12″ from the floor not 32″ as shown in the picture on the left hand side. My concern the bathroom sink drain is below the kitchen drain. Is he right?
