Hello all, Perhaps those of you with a 37/40+ can provide some guidance. The surveyor suggested adding a vented loop to the waste hose leading from the head to the through-hull. This makes sense to me. However, in looking at the hose, it seems to lead from the through-hull under the sink, way up, probably behind the mirror/medicine cabinet assembly, and then back down to the y-valve leading to the head. I'm guessing that vented loops were standard back in '94, so there may be one up where I cannot see the top of the loop. I'm also a bit concerned about getting very stiff hose to actually attach well to the vented loop.
The head tends to backfill waste up about 1/3 of the way, especially if it is not vigorously pumped and the handle locked down. It is a Jabsco. I am happy to replace the joker valve simply to be proactive. If, however there is a need for a vented loop to prevent backfilling, I'd like to put one in. The question is, how would I get to the top bend of the sanitation hose? Thanks in advance!!! Bruce Whitmore (847) 404-5092 (mobile) bwhitm...@sbcglobal.net
