Water pressure Psi?

[Kirkian301]

I have a 2009 Winnebago Journey 34y. No matter where I go, I always use a water pressure regulator on the city water supply when I hook up. Unfortunately, some of the supply lines are under pressure due to being from a well or otherwise. This leaves the water pressure in the coach, especially the shower, woefully wanting. Does anyone know the maximum unregulated water pressure allowed in the coach. I bought a gauge and can check it before hooking up. I was told the line is 50psi but I wanted to make sure.

The regulator protects you 24/7 of the time when it is installed. Measuring pressure does not protect you as the CG pressure fluctuates over the course of the day/night. It is rather common for CG water pressure to surge very high at various times.

Leave the regulator connected, it won't reduce pressure if the incoming pressure is below the set point.

Hi and welcome to the forum!

By "regulator" do you mean one of those $10 brass things which go in line with your city water hose? If so, I found those actually did reduce my water pressure in cases of low park pressure so I went to a Watts residential adjustable regulator with pressure gauges on both sides of it. I have it set to 50lbs.

I would not recommend going without a regulator of some kind for the reasons ottffss outlined.

Have you tried turning on your water pump while connected to city water? It can help in some cases.

We were told by an "expert" we trust that 60# was ok for our motorhome water system. A lot of people on forums like this say 50. We set our regulator at 50-55# and have had no issues. If you are using a good regulator (Watts) there should be no pressure drop. Many of the cheap ones that are sold at rv supply places drop pressure a lot. We added a gauge to our regulator so we can measure pressure any time we want.

Been running mine at 55PSI with a Watts regulator,for a lot of years with no problems. I carry a screw on the faucet gauge with me so that if I have really low pressure, I can check and see if its my regulator of the CG water system.

Where I live, the county water system can go above 200PSI sometimes and there is a few campgrounds in the area that is on this system.

[ottffss]

The general consensus is that RVIA certification specs a 100psi water pressure leak test when the rig is built (I have not personally read the spec) and that folks will run 45-55PSI on a regulator always in-line.

Basically all US made RVs have the RVIA certified label...

Get a lager Watts brand regulator with a pressure gauge. With 45 to 50 psig pressure, and a decent regulator, you will have plenty of water pressure in the coach for a shower.

I have been running my Watts whole house regulator at 60 psi for 8 years and have stayed at RV parks with water pressures from 80 to 125 psi for months at a time with no problems.

Thought the motor home is labeled "45psi max" the most senistive component can take 60 psi.

IF YOU USE A FILTER this will restrict the flow, increasing the PSI "up-stream" of the filter will improve your flow rate, However if you do that you need a 2nd regulator "Downstream" of the filter,

I use a Sure-flo set to 50 PSI post filter. , a Watts set to around 65 Upstream.

Please help me understand;;;; the Motorhome (ours included) states 40-45 Lbs' why in the world would you use anything above that... Oh I almost forgot. In a 65MPH speed zone There is allways that &%$#@$& has to be going 75MPH;; Life is good.

[Qwert66]

For those of you that use a watts regulator - what Watts # do you use ?
I'm concerned about psi drop vs flow but want to add one.
Thanks and not meant to change the OP topic.

Not sure what you mean by "the Motorhome states".

Do you mean what PSI? Mine is set at 50 and it seems to be plenty.

Where do you buy a Watts regulator and how much??

[John H...]

I use a watts regulator and set from 45 to 50 lbs. If are connections are tight you should be able to handle 60 lbs.

Home Depot or Lowes. I think they're around $65. Adjustable for whatever pressure you like. Mine is attached to my water softener with pressure gauges on both inlet and outlet to show me it's working.

Is this the one ? Seems it would do the job in a "'3/4 *lead free" format.

Shows $69.00 at Lowe's search.
At 5gpm shows appx. 7psi drop.
My only concern would be the ability to bypass (at a loss in protection) when you get a 30-40psi type low park feed which would then be further reduced appx 5-7psi drop which could show up in a lo-flo.
Seems you can't have both hi-psi protection and 0 regulated psi loss.
Just looking for actual experiences.

[John H...]

No, That is not what your looking for. Mine is smaller and has a tee to hook up seperate hose and also comes with a guage to set water pressure.

[John H...]

Here is one on ebay that is useable and you could add your own tee. Hope the link works.

My motor home is not labeled 40/45 and Winnebago says 65 psi is fine.
They test way above that pressure.
I would not exceed a labeled maximum though.

Thanks to all of you that replied with excellent information on my water pressure question. A watts regulator with double gauges it is.
