Proper Spot for Water Pressure Regulator
Where is the best place to put the water pressure regulator? At the rv park spigot or at the rv fresh water inlet.

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..
Since you asked...
Newer RV's have a backflow check valve installed at the city water connection. Without that valve, your water pump could pump the water from your FW tank back into the CG system. Not nice.
Also even though water lines have a high pressure rating they connect to the system via untested fitting. Excessive pressure in the line might not burst the line but will usually cause a fitting to spring a leak or come apart flooding the trailer.
CG don't guarantee their water pressure so having a cheap $10 pressure regulator attached to the CG spigot is very cheap insurance.
