Been using tank/pump exclusively since 2008 due to MAJOR flood while connected to city water with regulator in service.
While sleeping a $0.50 fitting gave way...water ran all night long. $6000+ repairs/costs and 2 weeks out of our lives (we were FTng) PITA!
Flip of a switch and pump is OFF when we go to bed, when we go outside/leave etc.
Consistent pressure/flow regardless of where we go
Refill tank as needed and top off before we go.
ONLY time we needs to be 'conservative' is when boondocking
If at a FHU CG Site...use the pump---let the water run. Fill tank while dumping waste tanks.
It's NOT complicated and after having an indoor swimming pool it eases ones mind.
