What is recommended water pressure for FF?

[Marti]

We are hooked up to house water hose, using a pressure regulator, but we are having some problems that seem to be pressure related. I don't know where the manual is or where to look online for that info.

I am going to try to find a meter somewhere today to see what the pressure really is. Any idea where to find one at local stores? There is a Camping World about 60 miles, Walmart and Ace hardware stores within 20 miles.

Any plumbing supply should be able to provide a water pressure gauge and fittings needed to determine water pressure.

I was not aware that you need a regulator when hooking up to house water. If I want to hook up my FF to the house, I just attach a garden hose and I get the same water pressure in the trailer as I have in the house. The only thing I have is a check to prevent water from going back into the house.

City/municipal water pressure varies somewhere between 50 -100 psi.

An average of about 70 psi is in the ballpark.

Ace should have one:
Brady 3/4in 100PSI Water Pressure Gauge/ Lead free (BTGIND CS-NL) - Accessories - Ace Hardware

What problems are you having?

The water heater leaks when it is heating. It never did that before. We bought a new regulator before hooking up here because our pressure was so low with the old one. But then the new regulator started leaking so we went back to the old one. Now the water heater isn't leaking but pressure is lousy.

I read other places that TTs lines can't handle the same pressure as a house.

As mentioned, most household water is ~50-100psi and water pressure at RV hookup sites are all over the place!

Most RV's (including Fun Finder) warn that you shouldn't subject your plumbing to more than about 50psi. Over than that, you risk leaks/damage.

Thats why you need to use the brass pressure on your incoming hose that knocks the pressure down to about 40-50psi. Maybe yours is old, and is not working well? For about $10 I'd replace it.

I recently suddenly lost pressure (hot & cold) to the kitchen faucet, and took it apart and found a large o-ring jammed against the little screen at the spout. Who knows where it came from. One day I'll find a drip in the lines and know where. Either that, or poor quality control (as usual) at the factory and it was an extra one left in the lines....

I *do* attach my house water to the trailer once each spring on full pressure without the regulator to look for any leaks or weak spots in the plumbing.

You can hook up high pressure city water for years without any problem, so some think the pressure regulators aren't necessary. But then, when you least expect it........

You didn't mention where your water heater is leaking from ... the water tank, the pressure relief valve, the hot water line from the water heater or ??

The newer TT lines are PEX line with the PEX crimp fittings .... the same as used in newer homes....so fail to see why a TT could not handle the same pressure as a site built house.

Or am I missing something ?

Some campgrounds have very high water pressure so several years ago, installed one of these so didn't have to carry 'another part to hook up' along.

hi all!

Do you think an RV water filter, one of the big white ones, decreases the water pressure enough that I don't need a water pressure regulator? This is the one I have http://amzn.to/2pyt723

we usually use the regulator in conjunction with it but I was just curious.

Unless plugged/clogged, I don't think a water filter would decrease water pressure any noticeable amount....but what does Culligan specs indicate?

[LJAZ]

Anytime you add something, like a filter, in the line you will have some pressure drop. How much will vary with the filter. And it will increase with use as the filter does what it's supposed to do and traps tiny particles that gradually plug up the holes in the filter.
