Water systems

They do this a lot in the States, but from memory you need a bit of extra kit to protect your system from teh pressure of teh mains water. try go2marine.com, as they are very helpful and can advise on tha gear.

I was thinking about some way of fitting a hose lock connector to a tee off the high pressurised side of the water pump and a pair of shut off valves, one to stop back pressure on the pump, one to stop pressured water exiting the alternative filling point when off mains water, but to be honest with you, filling the tankls every couple of weeks is not that great a hassle. it also encourages you to be mean with water, which is no bad thing

Is it not just a case of a conventional inline "non return valve installed into the live side of the domestic water pump feed with a tee beyond that ( towards the usage points say a couple of feet max) connecting the mains (off the leg of the tee) with a pressure reducing gismo set just above the pump pressure (to keep the non return valve closed when mains are used) another, inline, non return valve would be needed in the mains feed to stop surcharging of the main (highly unlikley but a legal requirement? in case of depressurisation of the main for whatever reason)? all these items are available from your local plumbers merchant and can pe found to fit "push fit" plumbing. worth considering having a bilge pump system that will keep up with any potential leakage or burst you might have. it could be feasible to come back after a couple of days, only and to find that your boat has sunk?

I work in a plumbers merchants and what has been said is feasable and the equipment is available but, what concerns me in this practice is what would happen if you were to suffer a burst pipe? Thats a hell of a lot of water that can come onto your boat in very short time. Even if your bilge pumps can keep up with the flow you would have to make sure they could cover for the lenght of time needed also. If not, your in trouble. There is a gadget available called a flood check valve which can shut the water off in the event of a burst pipe but in my expierience I wouldn't trust them completely and I will not be installing this system on my boat.

Seen it done, but complaint was that water tasted of "plastic".

The chap who had done it was a builder and he'd just put a pipe, from a hose-connector into his system the high-pressure side of his water-system pressurising pump.

This was in Vila Real where frosts are as common as hens' teeth.

The same question was asked on another forum recently and some one from the States said that boats regularly sank over there because of pipe or fitting failures.

Therefore not recommended.

How about a ball cock type valve in the fresh water tank, that way if the valve fails it should just overflow overboard through the tank vent. Also you'll still have water if the dock supply freezes (or your connection hose for that matter).
