Water Pressure Regulator

Can anyone recommend a well made pressure regulator that attaches at the spigot?

I've had to get them for the motorhome. Any RV store would have them, maybe a Home Depot or Lowes would too. They come in various PSI outputs, so know what you need before you walk in to buy one. I think I've got the thing at home, if I can find it, I'll shoot the brand name when I get home.

Have you checked the marine stores? West Marine, etc.? That's where I would start my search.

Are you replacing a failed one or installing one where there was none before?

Jabsco.

The one I have at home is by Norgren. Looks like mogel # R06-221-NNEA.

It takes up to 400 PSI in and you can adjust the output PSI up to 60 PSI.

Hope this is 2what you're looking for.

Jabsco makes a plastic one: Water Pressure Regulator In-line Garden Hose 44411-0045
Watts makes a brass one.
We don't seem to sell as many pressure regulators as we used to. I don't think many people hook dock water into their boat systems as they used to. I guess they are afraid that a hose on the boat will break and sink the boat.

Thanks all. We generally hook to dock water, but The Gulfport Marina has more pressure than I am comfortable with. Our water hose swells A LOT when hooked up, and I am really concerned how well the water lines in the boat would hold up.

I would think that if your boat's potable water system was designed to be connected to a city water system it would already have a pressure regulator as part of the system.

Of course, regulators can wear out or fail and this is where the sinking risk comes in. Many of the potable water systems on our boats are designed for 40 PSI or less. City water pressure can reach over 100 PSI (it's usually about 60 PSI but it can vary quite a bit depending on water consumption on a line at a given time).

A broken waterline on a boat that's connected to city water will result in a sinking if not caught and corrected pretty quickly.

I have one I bought in a marine store some time ago that's adjustable with a gage on it. Lasted for 10 plus years. I don't use it anymore with the current boat as we use tank water exclusively.

The better units like Jays can be disassembled and cleaned.

The cheap stuff is throwaway when it fails.

Your RV store or marina will have both.

Re-reading the original post, I see that this is not to be part of the boat, but an external regulator in addition to the one on the boat.

My suggestion is to go to a local plumbing supply house and ask them what's best for your situation. They will have a better selection than a home center, often better quality, and people who know plumbing parts.

Ron,
I think you are right. As was recently mentioned, which I didn't consider, the boat has a regulator at the water inlet. Assuming it works ok, I guess it is actually my hose to the boat I am trying to protect!

Cool idea. One that hooks right to the spigot.

Invent one.

That or get a bigger/better hose.:lol:

Why bother when they're available at the home improvement, hardware, camping and marine supply stores nationwide.

I've used a brass inline regulator in years past and seem to remember that it was a little "iffy" in my book. Didn't know if it was working or not. As suggested, I think I would like to get an adjustable one with a gauge from a plumbing wholesaler, and probably fab a short hose to feed it from the existing spigot.

many RVers uses a short length of hose like a washing machine hose to a "Y", with one other end to a pressure guage, the other to an adjustable house regulator then to a whole house sediment filter, then the hose to the boat.

This lets you adjust the pressure to what you want and trap any crap that may have been in the dock lines befor you got there. The whole setup is compact enough to fit into a milk crate with your supply hose and costs less than $100 or so.

This is what the Jabsco Pressure Reducer looks like. It will take pressures up to 150 PSI and reduce it to about 45 PSI. It has a female garden hose thread on one end and a male on the other. It sells for about 30 bucks.

Apollo (Conbraco) is a brand of high quality plumbing equipment including pressure reducing valves. Your local plumbing supply house will have them. These are the devices used in residential and commercial buildings and are much more reliable than a plastic pressure reducer.

If you want, you can add a gauge by screwwing a "T" onto the output of the reducing valve.
