check valve & regulator
i'm looking for a check valve that goes from my pump to water system (prevents backwater from entering freshwater tank when system is under city water pressure).
i'm also looking to get a regulator that goes from the city water inlet to the water system (prevents water going out the inlet when dry camping).
i've been searching on the forums and online and haven't had any luck. does anyone know which one i should get and where to purchase it? an online resource would be great.
