Last month we talked about the EZ Fill Funnel Filler and the Hose Filler Adapter.  One thing we didn't talk about was the effect of Water Pressure Regulators on your water flow.  If you go to a park that has decent water pressure and you use a normal pressure regulator the pressure will be reduced to 40-45 psi.  This reduces flow as well as pressure, a common complaint, especially in the shower.   Todays rigs are designed to handle decent water pressure but don't like high pressure such as 80 psi or above.  So if you go to a park with good pressure and use the standard pressure regulator, you will probably be complaining.  The Hi-Flo Pressure Regulator we use has a 55-60 PSI rating so the flow and pressure are much better.  Of course that depends on the campground having pressure higher than 40-45.  You will be pleasantly surprised more often that not when you use a pressure regulator that will allow more flow and pressure through to your rig, while at the same time protecting your plumbing.
