Jabsco 12V Single Stack Water Pressure System

The Jabsco 12V Single Stack Water Pressure System arrives fully assembled, with a Par-Max 4.0 pump, a strainer, and a pre-pressurized accumulator tank in one unit. It delivers 4.8 GPM, shuts off at 40 PSI, and is sized for boats with four or more outlets. The pump self-primes up to 10 feet, can run dry without damage, and has thermal overload protection.

Pressure water makes faucets and showers work the way they do at home, and it is one of the most noticeable upgrades on a cruising boat. The accumulator smooths the flow and cuts down on pump cycling when a faucet is only slightly open. Because the system comes preassembled, installation comes down to mounting the unit and connecting the inlet, outlet, and power.

Connections take 3/4-inch hose tails, and the unit should be mounted where you can reach the strainer for cleaning. Check the accumulator's air charge each season, and winterize the system along with the rest of the freshwater plumbing.
