Water pressure

Wondering what the proper water pressure should be going into a coach. I assume no more than 40 psi and every coach relatively the same so you donít bust the lines?

Any input will be welcomed.

Thank you

Jim

I keep my water regulator set at 55. I suspect most late model coaches could handle much higher.

I run mine at 70. That’s if wherever I am can provide it. It seems like many if not most RV parks run anywhere between 45 and 60, at least what we’ve seen thus far so we go with whatever.

Havent run a regulator. I have water going thru 1 filter then thru water softner then it goes thru the coach filter. That keeps my pressure steady

50 to 55 for me- I have an adjustable regulator but rarely have to adjust it.

I thought the same thing. Then, while cleaning the 12v pump bowl I learned the 12v pump is at 55 psi. So I turned my regulator up to 55 psi.

It's going to vary by coach since it depends on how they actually did the plumbing. If you don't have an answer specific to you, assume 40psi for older stuff and 50psi for newer.

If you find yourself wishing for more pressure, e.g. when someone's using the shower, you may be able to turn on your water pump. The pump should supplement your city water with water from the fresh tank to maintain 50psi (or whatever it's set to). Obviously depends on your coach being plumbed a certain way and also on you having fresh water in the tank, but it may be worth trying.

Thanks for the great feedback. I gave a new 2018 Tiffin gas coach. I guess 50-55 will doing the trick. I like the idea of using the water pump as well. I look into that.

Thank you all

Jim

I set mine to 55. I have PEX water lines. 12 volt pumps seems to put out at least that amount as well.

Me too! IMO the weakest link is the water hose, especially as they age, then lying out in the sun most of the time doesn't help the situation.
We stay at this one CG where the owner has a sign saying that if you do not use a pressure regulator, and you have a hose burst, it is a $100 charge for excess water used.

Tiffin tests to 100psi, but cautions to not go over 60psi. I've been in campgrounds with as high as 125psi & as low as 20psi. Have always used a regulator to keep the high ones in check.

You can go more than 40psi.

IMO, every RV owner should have a regulator on their hose/filter system before coming into the coach/RV. Every CG/city water pressure source will vary, so that's why a regulator should be used. Each owner should regulate what comes into their RV. 60 psi is usually the high safe zone or less that most say you should allow, thereby erroring on the safe side.

For us, we usually run anywhere between 40 and 55 and do fine. Vary rarely do we adjust our regulator. We also have 2 additional water filters and a water softener down stream after the blue Camco water filter at these pressure levels and do fine.

BTW...as another safety precaution, always turn OFF your water main whenever you leave your RV for any extended period of time.

Now why didn't I think to this? Thanks for the brain reset.
