Pressure regulator for city water

I keep reading that I need a regulator for city water hook up. I have seen these at the store but have not bought one yet because it seems to be just a brass fitting that restricts water flow like the 45 elbow that I have or the Y connection that I attach to the city water supply. I'm I thinking right or should I buy a pressure regulator?


Looking forward to first use.

I would. They are cheap and good insurance for your TT's plumbing. You wouldn't want 100 psi of water running through the plumbing of your TT.

Yes you want one. City water pressure can change drastically. If it goes high it can blow your water lines. There are expensive water pressure regulator, some that are adjustable, but the basic one will work just fine. Also you want to install it at the water source. That way your hoses, filterers, or anything else on the water line are also protected.

Yes get one. Even if you have a shut off valve and close it down if the what pressure is 80 psi you will get 80 psi if it is partly open or fully opened. The regulators have a valve and a preset spring in it to maintain 45 psi no matter what. I work for a rural water company and this is what we use to maintain pressure to our customers that need with high pressure. Will keep all the surprises out.Water flowing out of the door as I have seen this before on other peoples. And I always shut the water off when I leave the camper for anytime at all.

Those little brass pressure regulators are cheap insurance I wouldn't be without.

With my luck, I'd blow a fitting at the worst possible time in the worst possible place.
Have you looked closely at the Jayco plumbing?

I tried one of the cheap Camco regulators and it failed. Fortunately, it failed in a manner that shut off water completely, so there's nothing that says it can't fail in the opposite way. Watts makes the best regulator you can buy and they are only around $75 dollars. Not cheap, but still better than fixing a water line break. I'm just not a fan of using cheap parts to protect expensive equipment. YMMV

I guess i have been lucky - Everywhere we go its usually the other problem of not having enough water pressure. When this happens I just fill up the fresh water tank and use my own on-board water pump which works just fine for our sinks etc...

We visit the same couple of state parks mostly here in VA and they have them already built-in to the water spigot.

Probably a good idea if you have a big trailer with lots of water lines running all over the place. It could take three or fours days to remove the bottom floor membrane to repair a water leak...

If the regulator is at the water source hose and everything is protected. But the hose can get hot in the sun and cause the pressure to increase for the hose and RV. Will this risk over pressure and problems in the RV. Would it be better to risk the hose and have the regulator at the RV fitting?

No, because hoses are made to withstand the temperatures that you encounter, even with it sitting in the sun. As far as a pressure buildup after the regulator, it's only going to build up tp so much and every time you open a faucet or flush the toilet, the pressure gets relieved.

I have a small brass regulator; however, I use one the disposable inline water filters. The brass regulator combined with the filter together reduce pressure to an unacceptable level.
