I put one in a Scotty I recently did over and they work fine for a single faucet potable water delivery system.
Its not a demand pump (but its not $100 either)
Its a pump with a faucet with a 12v switch for on and off.
Very simple system, I converted a Kitty Litter bucket for the potable tank.
$65 new, I'm asking $40 delivered.
Happy Trails
