Yesterday, I attempted to hook up my ASI camper to city water.  I
attached the hose to the pressure regulator and turned on the water.
Water squirted everywhere!,  but alas no leak- the water was coming out
of a small hole on the side of the regulator.  Is this some sort of
relief valve, and how can I make it stop?  Do I need a new one?  Where
to get one?  THANKS!

Matt :)
