low water pressure

Ropdoc - what was the outcome?

Is your water pressure any better using your fresh water tank and pump?
EDIT: LOL, sorry Bob, didn't see the end of your post

Is this a problem that exists at you current campground. Some states require campgrounds to have flow restrictors in the faucet. When a flow restrictor is used you cannot screw the hose on with the standard screen in the hose fitting. The screen will not allow the flow restrictor to operate. When a flow restrictor is in a faucet you will never be able to get the pressure that you need. Pressure regulators can and do go bad so your problem could be a stopped up regulator. Try putting water in your fresh water tank and see what your pressure is like with your water pump running. If it has good pressure then it is not in your plumbing.

Is this a new problem? Or one you've had all along?

The problem may be low pressure or it may be low flow.

Tell me when you first turn on the water is the pressure good for a second or two then drops off?

Many people go to the RV store and get an RV water pressure regulator, this is a brass or plastic cylinder about 3/4" in diamater with male and female hose fittings one on one end the other on the other.. Some have a bright plastic grip on the female end or wings on the plastic body, THESE ARE JUNK and should be left in the store.

Valterra makes an adjustable. Friends who have tried it say it's OK

I have both a Watts and a Zurin and a Sur-Flo The Sur Flo is the one built into many RV's.. WHEN NEW these all worked well, I give the Sur-Flo a 9 and the others 10+. As they age they do "Slow down" and become more like the cheap cylinder ones above, but they can be easily rebuilt.. Though I've yet to get the kits.. More a "yet to get" than anything else.. I mean it took me six months to get a new ladder to replace my little 2 step job. And that is a needed item.. So imagine how long it will take to get the rebuild kit :).

If low pressure is happening the same at all faucets and toilet:
Check the city water inlet on the outside. They have a filter screen that can get plugged up. Behind the city water inlet, there is a check valve and they can also get plugged up. As mentioned, look for a filter.

If only one particular faucet:
Remove, inspect and clean the aerator. If no help, the cartridge in the valve could be plugged up.

It is possible to have a kinked PEX line, but unlikely. We had a totally kinked PEX line to our shower that came from the factory that way.

What are you using for a regulator? Have you checked the pressure/flow on at the outlet side of the regulator and also at end of the hose before connecting to the city water inlet? Could try running some water from your fresh water tank to see if there's a difference.

If you don't have at least a sediment filter, it might help to get one. You could try setting the regulator a bit higher. I have ours set at 65 psi (as recommended by RVwaterfilterstore.com).

Try removing the regulator (if the CG/park pressure is not too high) and see if that changes anything. If you have a Watts regulator, they can get plugged up but you can take them apart and rebuild it with a rebuild kit.

The first guess would be your water filter needs changing.

I do not know if we do or not. How would I find it?

I only know where my filter is which is behind the water panel in an outside compartment. If you have such a panel, feel up behind it and maybe look with a mirror. My filter housing is off white and about 4 - 5" in diameter by 8 - 9" tall. It unscrews and the filter is inside of it.



Look on the left side of the picture in just about the middle. You'll see the bottom of the filter housing sticking down behind the panel.

Also, include what type, year, model etc your MH is to see if someone else has the same one.

I checked all that. I even ran the facet without the hose on it.
