Water Pressure Restrictor

I have a Greyhawk 31FS. Does anyone know if there is a built in water pressure restrictor?

If you mean a pressure regulator, the answer is no. However there are likely restrictions in your water system such as the flow restrictors in your faucets and shower head. If you have a whole-house water filter it also will restrict the flow somewhat, especially as it captures sediments with use.

There are some campgrounds with water pressure so high it can damage your plumbing. I suggest you invest in a quality regulator with a gauge to protect your system.

Iím in one now with 100psi. I checked it when we arrived st 50psi but later it rose to a pressure that would have damaged my plumbing.

There is a restriction I believe on the water inlet out side, I know because when I winterize it sometimes a pain to get the pink stuff started, always used a pressure regulator in campgrounds

The restriction at the water inlet is likely the backflow check valve keeping system pressure from leaking back out the inlet. It is not unusual that some owners have to flip the inlet screen thereby "depressing" the check valve making it easier to draw antifreeze in through the inlet connection.

But as you note a pressure regulator is still required since the inlet check valve is not a pressure regulator.

You need to monitor the water pressure coming in. If it’s high then you need to reduce it or you could have leaks or worse. Remember that most Rv parks are using well water which varies in pressure and sediments.

We always use a hose filter and pressure gauge. At the motorhome we use a 90 degree quick disconnect to make hookups easier and to relieve the stress off the plastic connector going into the motorhome. If we need to install a pressure reducer it will go after the filter and pressure gauge to protect the water hose from excessive pressure and possibly bursting.

Remember to always turn off the water to your motorhome while you are away for extended periods. This will help prevent possibly flooding of your Rv if something happens and your gone. It has happened. Luckily not to us.

I made my own setup. I purchased a Y hose connector with separate cutoffs and a pressure gauge used on lawn sprinkler systems Both can be found at any hardware store. About $10 bucks for both. The filters you can get at Walmart or any RV parts place. The filters are good for keeping trash out of your system. If you plan to drink the water from the rv park be sure to filter it again using a filter made for filtering drinking water. Don't trust the water at any rv park.

We use the Aquasana purchased from Costco but available other places. It's narrow design fits nicely on the counter in the motorhome and makes plenty of water for drinking, coffee and tea. We have one in our stick house also.

Always use some kind of pressure control on your water supply. I stayed at a park year before last in Missouri that had 95 lbs. More than enough to burst a pipe in my rig. I have not sprung for one of the good adjustable ones with a gauge yet, but I wish I had just done that at the outset since I have purchased 2 of the little in-line ones...

Set at 60psi, but when I check the gauge the campground pressure it is usually less than 60psi.

55 psi on mine, but like oldmanAZ I seldom even get that. Not often does it actually read 55 indicating it is that pressure or even higher. The majority of places I have stayed it is between 40 - 50 psi.
