Re: new trick for removing head hoses!
There is a hard connection from tank to PVC, both inflow and outflow. There is a short bit of flexi pipe joining the toilet to the PVC. This is a low point, and may become permeated. But it is only a handful of inches, and perhaps I'd change it each winter. With the rubber cuff on the end of the flexi pipe, and short length of flexi pipe itself, I hope this gives enough movement. At the pumpout side, there is a longer section of flexi pipe, but it is uphill just below deck level, where sewage will never be collecting. It will take years for that piece to permeate. The PVC pipe does not touch any part of the boat anywhere but the hard connection at the tank, and the flexi pipe at the other end. Anywhere it passes thought a bulkhead or anything, there is a large enough cutout to allow for a bit of movement.
I think I'm okay mechanically.
Oh by the way, I am pretty sure the piping I replaced last winter (before re-replacing and shortening runs with PVC) was original to the 1979 boat. Ewww.
