Happy New year from new member
We bought a 2008 Colorado 31 ft fifth wheel last spring in Az. to winter in. Replaced Kitchen and shower taps so far. The reason I signed up on here was the black tank sani flush gushed water all over the kitchen floor on the other side of the trailer from the inlet hose connection and hose connection to the tank which was only about three feet apart. Anyways after reading on here I found the check valve on the other side of the trailer and the leak up the wall behind the shower. So i got rid of both lines going across to the check valve on the other side and ran a 3' supply from the hose inlet direct to the tank. I have a hose bib check valve coming to install and should be good. I tested the new setup and it worked like a charm. So Happy New Year and thanks for the info on here which helped me fix my problem.
