Which is why I pointed out "so many variables!"

But thanks for making my point for me.

The regulator regulates it.

Its so funny to hear from people form California.. where the temps stay temperate but water is scarce.. Around here we don't bat an eye at dumping 10 gallons of water.. heck, even a few 100 on the lawn just to make it pretty is no issue at all.

Actually is you are really hard up for water, then I would actually recommend the on-board tank method. It tends to encourage conservation and prevents the possibility of a ruptured hose which would dump water endlessly until discovered.

But, isn't $12 for a regulator and peace of mind a small price to pay?
Gordon2. You need to read the thread again. I believe you and I are saying the same thing.

The 150 PSI relief valve on water heaters is an emergency pop-off valve that opens only in the event of a run-away overheat. It does nothing to control or regulate pressure, it's not even in the water lines and, if it does open, you will have water all over the place.


If it were the case, every time I turned on the hot water in my RV or my house, the hot water would have higher pressure, but it doesn't.

The valve on your water heater is a *combination* device. It opens when temperature is too high, or when pressure is too high. You are correct in that is does not control pressure.

The reason the water pressure in your house never gets high when your water heater comes on is two-fold. 1) you are not starting with cold water, so there is less expansion when the water heats up. 2) Your house probably does not have a one-way check valve where the water enters your house. This means that any expansion due to water heating is pushed back into the city water system. If it does have a check valve, you probably have an expansion tank that will limit the pressure rise.

My house has a pressure reduction device between the mains and house plumbing. Just because you can't see it, doesn't mean it's not there.
The RV does not, so a pressure reduction valve is required to protect your plumbing.
Very simple, and less than $12.

There is a backflow preventer on the main lines in most houses to prevent contaminating of the water supply. Mine is right at the output side of the meter.

I started to hook up at a park last spring when an adjacent camper came over and warned me that the pressure was in excess of 100 psi. I did not hook up. He showed me his Watts adjustable regulator with a gauge on one end. When I returned home I put together a regulator from a picture I took of his regulator. It works well and gives me piece of mind. No blown hoses, no worry about pressure fluxuation, great conversation starter from those with a twinge of concern and no gauge.

Interesting thread with a lot of comments for the OP to read to the original question although some went a little sideways and have nothing to do with a trailer. Bottom line to the OP is use a regulator when connected to any city water connection.....just cuz, it's cheap insurance. At the hose bib, to protect the hose too, or at the trailer, it will protect the trailers internal water lines/connections.

No one mentioned that Scamp has installed a pressure protection within the system to prevent damage from excessive campground water pressure. At least I have understood that my 2013 model had such.

David do you know what model year Scamp started to add them into the system? I know for sure that mine did not have one.

Given that a water pressure regulator is cheap and easy to obtain, and attaches to the faucet, I can't imagine Scamp going to the effort and expense of installing one inline.
I would certainly confirm with Scamp rather than rely on web.
