From Caltex.... "You couldn't hear the water pump? There are benefits to having noisy ones, which most FW pumps are."

I added 2 small lights to the overhead of my helm instrument panel. One for the head pump, one for the FW pump.
I have put a lot of 'perfume on this pig.' I am sure the next owner will appreciate it.
In my shower, I can hear the FW pump cycling and also the shower sump pump operating. They must be very noisy because I am hard of hearing and never wear my hearing aids in the shower. SMIRK
I have also added a whistle light, (for the hearing impaired?). I blow the whistle and a light goes on at the top of the stack.

Lol. I found mine during survey. PO had never used it. I have never used it in 6 years

The foolproof way of not sinking a boat from city water is to not hook the boat to city water. Fill the tanks and use water from the tanks. Anything else is taking a risk. Your risk tolerance is up to you but remember, even if you have never seen a boat sink from being connected to the city water system, it can and has happened.

What worries me about these shutoff devices is, they are often made of plastic and not built to the reliability that I would want to protect my boat. I would feel better about one made to commercial or industrial standards.

I use the water from my tanks and it's never been a problem. And as someone pointed out, it keeps the tanks fresh.
What is the big deal about using tank water and filling up occasionally? Valves, pressure reducers, this, that, none of it for me. But, I make no judgment on the choices of others as long as they fully understand the risks and benefits.

And in our marina the dockside water pressure (long run from a well, not high pressure city water) is less than what our onboard pump supplies. Dock water pressure is not sufficient to properly supply our new Raritan Elegance toilets.

Just remember to turn it back down when you are finished.

- I'm too lazy to disconnect and roll up the hose every time I want to use the boat.

The only negative I can see is the pump wearing out sooner.

If I was a live aboard and stayed at the dock, I'm sure I'd have a different view.
I am a liveaboard and stay at the dock and don't have a different opinion. We fill our tanks every three to four weeks.

Thus why some use city water.....

If I could go 3 or 4 weeks without conserving water, I too might just use my tanks.

I hang my white hose over the side of the boat, no goo on the deck or the side of the boat.
I would like to be given the option of service (water and shore power) forward or aft but, the AT34 only has service aft.
I like to come in bow first so folks cant look into my "living room" plus, the tender hangs in davits aft.

So my set up is this. Pressure regulator (adjustable) connected to the boat. I have city water to the dock and is fed into a charcoal filter with a reel so I can run water anywhere on my dock.

hooking up a flow restrictor such as an orifice or gate valve prior to the boat hookup WILL NOT reduce the pressure in the line. it will only reduce the flow if you have a fitting blow off inside the boat. You would need a pressure reducer with numerous moving parts that can fail do to a freeze. Pressure across an orifice is only reduced when flow is moving across the orifice. (Bernoulli's Principle). once you turn off a faucet inside the boat the pressure throughout the boat is the same as dockside pressure. If you don't believe me put a pressure gauge on both sides of your gate valve or orifice.

That's one reason why you'd prefer to have it inside the boat. And no, they do not have numerous moving parts.
By the way, most marinas turn off the dock water during a freeze. Know any that don't?

I don't think anyone said a restrictor would drop the pressure but it will slow the sink rate of the vessel if something catastrophic happened on the pressure water system with dock water pressure filling your boat. It might give your bilge pumps a chance.

the dockside hookups they sell at marine stores like West Marine are pressure reducers and they reduce the city water to 40 psi. In the last 35 years I have had 2 of these fail due to contamination and freezing. And yes, in New Jersey this year we had an early freeze and the marinas did not shut off the dockside water.

If your marina shuts off the water during freezing weather or if they don't and the water lines freeze and burst, you'll be glad you are using water from your tanks.

If you insist on using city water and leaving it connected and turned on, the safest thing would be one of the devices that shuts the water off after a set amount flows through the device. The problem is, a device made for watering the lawn is most likely plastic and not robust and reliable enough to trust your boat to.

The cheap plastic meter is only a backup to a backup safety issue....the 3rd level of risk mitigation if you havent upgraded your fresh water system.....at least make the debate plausible.....

There is a possibility that another boater will accidentally turn your water back on when trying to turn his on. It's safest to disconnect the hose. A "quick connect" makes this easy.

or the fifth level of risk mitigation...have the turn off on your boat before it hits the city water connection.....

some of us have been doing this long enough to know the tricks and pitfalls...

thats why we use city water and ignore all the fearmongerers....

Yep, that's our routine. As we walk away from our boat, I pull a quick connect on a hose running along a dock post, then close a valve on the hose anyway, then the valve on the dock supply. If my boat ever sinks from running water, it was a freak water spout from Florida that lost its way up the Missouri River.

Back in the day we would remove the rubber feet and hard mount it when ocean sailing.

LOUD is good when the next water is 500 NM away!

I was looking at the "rules" of a local marina that we are considering moving to and one of the requirements is that water hoses be disconnected when the owner is away from the boat. I assume this is even for those who have been boating a long time.

Walking the docks, I saw hoses rolled up and disconnected.
