Fresh water pressure system leak

[Paul Beardsworth]

Has any body experienced leaks in their pressure water system. I have a 1990 41 s5 First and it appears to be in a place that I can't get at. Its in a section between the nav table and the aft head and it appears that the only way to get at the leak is to cut fiberglass which I'm loath to do.

This is a problem with a lot of Beneteaus (and I am sure other brands too) of certain vintages where they place plumbing and electrical/electronic wires between the hull and the floor pan with no access to deal with your sort of problem. Boats that have floor boards that can be lifted to gain access to such things are well worth it, but many buyers do not think of such things. OK, off my soap box. All you can hope do do is perhaps pull the hose back where you can access it and then fix the problem and feed it back. Tying a messenger line to it before you pull it out might help you feed it back when you are done. I would hope, however, that no connections would be used in the areas that you cannot access. That would be crazy on the part of the manufacturer. But, then they don't have to deal with fixing it years down the line. They are interested in selling the boat and getting their money. The owner can deal with the manufacturer created night mares (and believe me, there are plenty of them out there).

I'm assuming its leaking at a split in the hose. Typically you don't expect to find complex fittings or manifolds hidden.

Assuming a split in the hose:

Buy a long hunk of replacement house, a barbed coupler, and some hose clamps

Undo the ends, and attached the coupler to one of the ends

Attach the new hose section to the coupler. Tape down or cut the clamp ends

Gently pull the old hose out from the other end. If it gets stuck, try to wiggle and turn it to unsnag it.
