WATER PRESSURE SETTING

[Larry-P]

I have a Watson adjustable water regulater on our unit. It's preset to 50 lbs. I'm thinking of increasing the pressure to 60 - 65 lbs.
We have a 2011 Monty. Would this unit take that pressure safely ??

The water system components are actually rated to about 100 psi. 60 psi should not be a problem. Now with all that said, if you have a problem, it is going to be at a junction point (elbow, etc.) or a connection. All you can do is try it and look. The system will support the added pressure, the installation (Amish craftsmen) may beg to differ.
Bingo

This is just my observation on the newer units (built with convenience center) with seemingly lesser shower, sink, lavoratory output than older models. With the addition of the convenience center came a bunch of extra valves and fittings for our added pleasure. Although right handy, it came at a price ... lesser flow than older models minus the center. Reason ... all the extra valves and some fittings have a much smaller hole than the 1/2" water line. Smaller hole = less flow at a given pressure. To support my reasoning, take a line off any one of the valves behind the center and look at the port diameter inside that valve.

For whatever reason I used to purchase regulators set to 40 psi. I have had about three of these fail over the years so I am now in the market to but an adjustable regulator as soon as the current one fails. The thing is this latest one won't fail. Go figure.

If and when I finally do this, the goal is to set the pressure to 60. I hope this improves the pressure because we have never liked the current pressure provided with the 40 lb setting. We understand the plumbing should handle this pressure and after 7 years of owning this rig, we have no reason to believe this is a bad idea in our 2006 unit. I also use a water pressure monitor right after the regulator to confirm the pressure being provided. To date, it's been on 40 lbs on the nose. In the future I hope to see 60.

When shopping for your new regulator, you should also consider flow rate as well as allowed pressure. They are not all the same. Get one with the highest flow rate you can find.

That's right. The small ones don't flow much water and of course cost less. Get a high flow, rebuildable unit.
Here's a nice article http://www.rv-dreams-journal.com/2010/05/rv-water-pressure-regulators-related-matters.html

The lines say something like 150 psi. I have our adjustable regulator set at 60 psi and have had for years. Back when we had a 1975 fifthwheel, those had those little elbow connectors in the lines to enable going around a corner. Those would blow off if pressure was too high. Plus, the lines in those days were not as strong as today's models.
