I agree, a good PDI should have caught this. The dealer where we bought both our campers does a very good check of all systems, including filling the fresh tank, running the pump, and checking that all water fixtures are in working order. I think a good PDI at the dealer may cost them a little more in people time, but sure does make a difference in happier customers. We have bought 2 different TT from the same dealer and have had NO problems at all, with either of them with factory or quality issues.
Glad you got it fixed, but hate that you had to go through the frustration. It certainly is not unreasonable to expect the major systems (water, LP, sewer, appliances) to work properly when you get a new TT.
