I have a 2002 National Tradewinds. It has a Shur-flo pressure regulator water entry valve. For the second time in about 6 weeks I have to replace this piece because it decreases water pressure to the coach to about 29 pounds of water pressure. Water out of the hose is at about 47 pounds. Is anybody else having this problem?

I often find the city pressure not to my liking. I run the water pump off the water tank, it's a much better option.

You could change it out to a non regulated check valve connector and put an external water pressure regulator on at the hose bibb. On parks that have only 50-60 psi or lower I don't even use a regulator.

Are you saying your inlet regulator is initially OK but after a few weeks drops to only 29 psi. Then you replace it and its OK again for awhile before dropping down again? Sounds like something may clogging the regulator and it sticks in partially closed position. Are you staying in one place or does this happen na matter where you travel? How many times have you replaced the inlet already?

Some of the inlet regulators can be pretty low to start with - I've seen them allow only 35 or so even when new. Ought to be at least 45-50, in my opinion.

Those regulators also have a limited flow rate, which is often the worse problem. As little as 1.5-2.0 gallons per minute is common. Most people would be happy at 30 psi if only the water flowed well. If you go with an external regulator, make sure you get a "whole house" size with a decent flow rate. Most of the ones sold in RV stores to screw onto water hoses don't pass much water, regardless of pressure. 2 gal/min tops. I like at least 3 or 4 ga/min.

I stay in one spot during the winter months and travel in the summer. We bought the coach last fall, so haven't traveled much in it. I use an external filter to trap an impurities that might plug the regulator. The regulator says on it that it regulates pressure down to 50 psi but doesn't say anything about flow. I'm going to contact Shurflo to ask them to warranty it. Thanks for the post.

I considered that, but my hole is square with 4 mounting holes. The only non-regulated ones I have found are round with less mounting holes. I'd have to manufacture a mounting plate to make it work. Thanks for the post!
