Home inspectors at Pacific Coast Inspections get excited when they open a cabinet door below a sink and see a drain pipe plumbing maze. Not only is it a photo op, but you have to say to yourself... "Are you kidding me?" This unusual plumbing configuration was spotted at a recent Walnut Creek home inspection. If you follow the water path from the sink drain... it drops 18" into a water trap which is okay... Then the water from the lowest trap is pushed up 8" into a second water trap... From this trap, water must flow straight up another 10" into the trap arm (the pipe that goes into the wall). Typical installations call for a water trap to sit 2-4" below the trap arm... not 18" with a double trap. Remember that the draining water from a sink isn't under pressure, but counts on gravity. This plumbing configuration worked, but as you can image... the sink drained slowly... and with the 7 fittings between the sink and trap arm, the probability of water leakage goes up with the number of pipe connections. |
