closeup[underneath[![side][2]][2]Recently decided to replace the drain in my bathroom and learned a little about p traps from the inter web. All the work was done by the previous owner. Was wondering if this is an acceptable configuration to act as a trap? Not too happy about how they cut into the ceiling joist either. Not a lot of room to work up there.[From underneathUnderneath

  • I posted a different pic that shows how the"p trap" is dipping down and then goes back up to the sewer line. Wondering if this is an acceptable way or is there a better way to do it. The drain is coming from my tub. – Robb Aug 6 '15 at 22:11

    If it were me, I'd replace it while I had it open. Galvanized pipe tends to look like a block artery after a while, so I personally replace it whenever I see it. Those Fernco couplings are great in a pinch, but I personally wouldn't use them in a closed up wall or ceiling. While you're there, you might as well redo it. – Tester101 Aug 6 '15 at 23:18
  • The pipes are in the ceiling of my unfinished basement so urgency isn't an issue. It's my first go at any plumbing project and I'm learning a lot. Everything is accessible so that will make things a bit better. Are there adapters that will attach from the little drain pipe to the final galvanized sewer pipe. Or should I get rid of the final sewer pip and run pvc pipe all the way back to the tree going into the ground? Thanks! – Robb Aug 7 '15 at 0:50

    Personally I'd install PVC as far as your comfort level and budget allow. – Tester101 Aug 7 '15 at 1:24
