My boat has, or had, two integral water tanks built into the sofas. When I bought the boat they were leaking inside due to cracking in the fibreglass tanks, which also have osmotic blisters on the inside. I'm only using one going forwards and will use the other for storage.

I'm planning to sheath the inside of the remaining one with biaxial glass, 2 layers of 600g and epoxy resin designed for food use.
There is an inlet pipe from the deck filler that needs to be sealed, that looks like it leaked. There is an outlet pipe that has a proper through fitting that goes to a jabsco par-max4 pump. The outlet of that disappears but presumably goes to the cold water tap and also a hot water calorifier.
There is also a return pipe that goes back to the tank with a through skin connector.

Is there an east coast expert who can explain how all this works , or even maybe check it over?

Why not just put a bladder in the old tank ?

This is going to sound dumb. I've got a bladder and put it in there. The inlet and outlet connect up but there is no fitting for this return pipe that goes back to the original tank. So I'm not sure what the return does and thought it might be easier to just fix one of the original tanjs

Isn't the "return pipe" a vent pipe?
