Proper Spot for Water Pressure Regulator

I used to put it on the camper side. Why reduce pressure the full length of a 25 ft hose. That hose ain't going to burst..

And by the way im a plumber 30 years ... AFAIK all potable water systems must have an 80 psi regulator. Just like a home to code..

And pex in the new campers is rated min. 160+ psi.

200°F at 80 psi
180°F at 100 psi
74°F at 160 psi

I have never been to a campground with high pressure.

Its urban ledgend from the old camper days with old quest pipe that got brittle from the hot and cold temps.

But I got suckered into the hype. And I should know better in my trade

I put a cheapo 55 psi camco inline but stopped using it with the new camper.

Here is the scam. The red line reads high # 50 psi here...LOLOL ha ha ha..



Let me ask ya all..

When your water heater heats up, how much pressure does it increase you rv's plumbing from thermal expansion???

becuase when you add these pressure regulators they act as a check valve. Now you make your water system a closed system... So the thermal expansion has no where to go. So when heating hot water you can build PSI in the camper up up up to way over 100 psi..

Without the reducer/.check valve the expansion will push back to the campground water system..

Just like in a home when this occurs expansion tanks are installed near the water heaters for this purpose. Whenever a pressure reducing valve is put on the homes system.

Same as an RV.

Anyones relief valve on their water heaters weep/drip? Now you know why....

Remove the PRV/checkvalve, or ass a accumulator exp tank.



Just my thoughts is all...;)
