H2O pump is running, no water flow
I am systems checking my new 2018 Micro Minnie trailer model 1808 FBS.
Hooked up to city water just fine, good flow in all faucets and shower.
Un hooked from city water, filled the fresh water holding tank.
Turned on the 12 V electric pump, I can hear the motor running.
Open a kitchen faucet, all I get is hissing air and a small amount of spitting water, no flow. Sounds like the pump may be cavitating.
I'm a real newbi to this world, so may be missing something obvious.
