    Bathroom Sink Won't Drain

    We have only been living in this house a few months but have began to notice our bathroom sink won't drain (water sits in the sink and drains very very slowly). I have taken the trap off, it wasn't blocked but gave it a clean anyway. Still the same issue, all other drains in the house seem to...

    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...

    Grout rinse water down the toilet

    I recently had a tile contractor redo some of my bathroom tiles and he dumped about half a bucket of the grout rinse water down my toilet. He did that before I could stop him, but now I'm worried I'm going to have drain clog issues. I poured down a couple of buckets of water down the toilet...

    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.
