    After scouring the forum pages and reading all the great advice, I had my water softening company set up a stand pipe that drains into the clean out. The clean out is for a bathroom on the other side of the wall. It was the only option we had. Now I’m wondering if they were also supposed to put...

    Vent Pipe Undersized

    I recently discovered that the vent pipe from my kitchen sink and dishwasher is undersized. The contractor routed what looks like 1" pipe through the wall (presumably because there wasn't enough room to route 2" pipe), which then feeds into a 2" pipe that leaves the house. There is no...
