City water pressure

[CaptDenny]

Have had the EXACT SAME PROBLEM. I assumed it was a bad WATER PRESSURE INLET to the boat so replaced it. No good so took that one back to West Marine and got a different one. Still no good. I never thought of it possible being a high pressure issue at the hose. Could be. BUT then heard of too many boats being sunk because of a bursting pipe inside the boat when nobody is aboard and the bilge pumps could not handle it. So I only use my fresh water tank by filling it every few days or so. No big deal but resting easy. SIDE NOTE: Had water joints give out more than 10 times in the 10 years I have owned this boat.
Usually an easy fix and the most water that can ever get into my bilge is 81 gallons.

Yes sunk boats have happened. I Never leave the dock water turned on when not at my boat and for that matter my rv either. I'm too paranoid to be gone with that hooked up and turned on. I've also installed a smart water valve at my house so I can turn it off with a schedule or my phone whenever I'm not there .

All these great suggestions and I can't get to my boat, Gezzzzzzzzz.

And yet everywhere else in Canada and probably the rest of the world, people are enjoying their boats. F is a four letter word!

Most of the time I use the water in my tanks. Occasionally I do hook up to city water but like others here when I leave the boat for any amount of time the water is shut off.

Same issue. Replaced the water pressure inlet thinking it was bad. Same thing. Tried a 3rd with no luck. I never thought of shutting down the flow at the dock. That might be the problem.
IN THE MEAN TIME ..... I have heard too many stories of water lines breaking while hooked up to dock water and somebody forgetting to turn it off while off the boat OR having turned it off and somebody turning it back on without your knowledge. Better safe than sorry.

The dockside water inlet is a check valve and pressure regulator all in one. It is uncommon, but sometimes air on the boat side of the system will lock up the check valve/ regulator. Disconnect the dock side water hose, open a faucet on the boat. Reconnect the dock side water but don't fully tighten the hose. Slightly crack the dockside water supply and let it run until all air is out of the supply hose, then tighten the hose at the boat connection.
If all of your components are good it should work.
I have only had this happen twice in the last 20 years. It was when dockside water had really high pressure, which is unusual around here.

Okay boater buddies! Went to the boat. Checked my filter and stuff. A okay. Take apart the regulator, clean and test. Ok. Going crazy, doesn’t make sense. Check tubes, ok. No pressure at 2 sinks, the galley and head. I decided to remove the faucet screen on the galley faucet, bingo! Full of crap!!!! And I use a filter! Go figure. Clean both screens, put together and wow!!!!! 100%

Thanks for posting however still makes no sense to me. You cleaned out the galley faucet screen and miraculously the other sinks/head get water?

[pepmyster]

I’ll explain, I had no pressure at the head sink and galley, the repair was just cleaning out the screens on the galley and head sink.
