Tackling a project this winter that's been crying out for attention... replacing at least some of the plumbing on my 1977 P30. When I bought her two seasons ago, my surveyor pointed out the puzzling connections shown below. The PO had installed a Y-valve on the intake line that would allow the head to be flushed with the contents of the holding tank (nasty, huh?). Can't understand the reasoning behind this except as a means of introducing as little water into the tank as possible during extended coastal hauls w/o pumpout facilities (??). SD has mentioned this configuration before on a previous boat he owned but I can't find any explanation behind it's purpose -- guessing and hoping he'll chime in
This configuration allows for either direct discharge (where allowed) bypassing the holding tank or straight to the holding tank, where it can be emptied either at a pumpout station, or macerated and pumped overboard.
I have several hoses to replace, but am looking for opinions or advice as to whether are ANY redeeming qualities to this layout or if I should just scrap it and start over using a simpler and more traditional layout. Thoughts? Thanks in advance.
