    I'm planning on tacking a bathroom remodel and would like some pro advice as to whether this is up to snuff or not. I've never done wet venting before, but apparently that is what used to be in the bathroom and I'm planning on slightly modifying. Originally there was a double vanity (on the...

    Wet Vent - Configuration A or B?

    I am grateful for your consideration. Is configuration A or B compliant with the UPC? I'm pretty sure A is but have doubts on B. If both are compliant, which would you prefer? Thanks!

    Bathroom venting question

    I'm replumbing an existing basement bathroom that doesn't have vents. Does this diagram look right? 1. Can I add a shower vent to the end of the 3" main horizontal waste line just beyond where the 2" shower line meets it? Is this to code? 2. If the sink is vented, do I even need to add a...
