RV WATER PRESSURE REGULATORS
Reiterating StirCrazy's concerns from an earlier post, wherein he was unknowingly experiencing 120 psi municipal water pressure spikes in his RV (spikes, if any, most often occur at night after industry shuts down and water demand slows, allowing pressure to rise). If you connect to a community water supply at campgrounds or RV parks (rather than simply filling your freshwater tank with a hose), you should definitely install a $15+ water pressure regulator, which limits water pressure into an RV at a manageable 40 to 55 psi. Very easy to install. There's many to choose from, adjustable and non-adjustable, with psi gauge and without. Google "Camco 40055" to Camco's website for a good description and photos of how they work.
And don't forget that while you can fill a freshwater tank with any garden hose so long as you flush it for at least 5 seconds (avoid dubious RV dump station hoses), for an RV park connection you need to use a "drinking water" hose, often white in color. These won't leech vinyl byproducts into the stored water as the hose warms in the sun.
I solely boondock camp, no utilities, so perhaps others can comment on their experience with these pressure regulators.
