Do not attach a hose to the boat and leave open. Should you be away from the boat and a fresh water fixture or line fails, you will fill the boat with water.

Don't think there is one unless a PO added it. We don't have one on our '95. I agree with John, I would not leave water hooked up and on. Water systems on boats are not like home systems that rarely leak. These systems leak regularly and high pressure from city water would likely make that problem worse.

The water system on the boat is definitely not designed for city water pressure. Seems to me it would be possible to design a method of refilling one selected tank, provided that the supply pressure could be reduced and provided the tank were isolated and safely vented overboard. Might need a separate small tank, kind of like the tank on a toilet, to manage flow. Think about it...just don't run municipal pressure straight into the boat's piping.

If we know more about you and your boat, where you're located, etc, we will be better able to help you. Are you a livaboard, is that why you need so much water on board?

I've seen boats with a transom mounted connection for a hose to the dock; I believe they have a pressure regulator in them of some sort. But a quick scan of West Marine and Defender didn't find one, so maybe they're not available anymore? May have sunk too many boats?

In any event, I wouldnt' have one on my boat for the above mentioned reasons. If I forgot to disconnect it when leaving the boat, it might wind up on the bottom. I shut all through hulls every time I leave the boat, and the water pressure a foot or two below the water line is miniscule compared to city water pressure. A case in point; when I fill my aft centerline water tank, I only stick the hose nozzle into the deck water fill part way, and listen for the vent on the transom to start gurgling, at which point I shut it off. This is before the tank starts to blow water out the vent. Yet I've observed the tank to be significantly bulged from the water pressure. So if that hose was directly attached, and the pressure not properly regulated, I think bad things would happen.

My slip neighbor has a water connection on his Beneteau and seems happy with it, but I don't want one on mine.

Check a RV dealer store. Most RV's have a fitting with a pressure reducer of some sort for hooking up to a city water supply.

This is one online source.

I know many liveaboards with shore water hookups. You just have to remember to shut the water off when you leave the boat. If you don't liveaboard, I wouldn't bother. However, if you do, when you get tired of filling the tanks every few days, you'll probably want one. Here's the water inlet with pressure regulator from Jabsco......

We had a discussion about this last fall that you might want to review, the thread is [url]http://www.c36ia.com/forums/showthread.php?t=1439%29[/url](link is external)

Our boat has a "City" water system -- I can't tell whether it was installed by a prior owner or a Catalina option, although I suspect it was the latter as our boatyard neighbor's Mk1 has the same setup. The plumbing scheme is as follows: after the on-board tank water has passed through the pressure pump, the accumulator tank, and a check valve, it reaches a Tee, where the City water line comes in (after having passed through the build-in pressure reducer at the hull fitting and its own inline check valve). From there the water supply proceeds to another Tee (dividing off a hose supplying the head sink cold water faucet), then another Tee (dividing off to hoses supplying the galley cold water faucet and the hot water heater).

The pressure reducer works so well that the City water is actually at a lower pressure than the onboard water (I know because I have to switch the pressure pump off, otherwise when we draw water it activates the pump and takes water from the tanks).

Its a very nice feature if one spends time living at the boat on a slip. The essential rule, however, if you choose to do this, is that you MUST disconnect the City water whenever you leave the boat, as insurance against a leak filling your boat while you are away!

I have one that was installed by the dealer. this is in the anchor locker. I have never used it. but we use a set up on our camping trailer that uses a hose and this water doesn't go thru the tanks. but I always shut off the water when leaving the trailer, which will not snik but can get very wet.
