RESOLVED. water pressure weirdness

IT TURNS OUT that the water pressure regulator actually does its job. It’s not necessary for me to adjust the valve to keep the needle in the green area, which is what I was doing, which is why I had little pressure. I can turn the valve on all the way and the regulator does the rest!! Oh me of little faith  

I'm hooked up to RV park water spigot with pressure regulator. Needle points to line between medium and high - until I turn on sink faucet when there’s pressure for a second and then it drops to almost “nil.” After being off for a minute, pressure returns but again drops after a second of use. 

For months I was hooked up to our outdoor spigot at home and I had consistent pressure with the needle that stayed in the green area. 

Any ideas? Do pressure regulators just wear out? Do RV parks have "governors" on the water pressure?

    Regulators can fail.  Also, if the pressure at the park is marginal to start with, a lot of campers using the water at the same time may impact available pressure.  How far are you from the spigot?

    @Sharon_is_SAM -Good question. It’s a 25’ garden hose but I’m 15’ from the spigot.  I should get one of those narrow curly hoses that’s 15’ long?

    I can’t do the math to know if you will benefit or not, but in general a shorter hose may give you more pressure.  Anytime you open a faucet with the system pressurized via the pump or city water, the pressure will drop.  Maybe it stays higher at home because the pressure at home is higher to begin with.  If your flow is adequate, don’t worry about it.  Lower pressure is better than higher.  One question though, why do you leave the TaB hooked up to city water at home?  Do you turn the water off when the RV is not in use (just in case of a leak)?

    I stayed in the TaB in my yard for many days and nights. To learn it, to get used to it, tweak it, make it comfy, figure out where everything could be stored, to feel at home. I’m living in it for three months this summer, far from home so wanted no surprises.
