Installation and Mounting

1: Select pump location. Pump must be installed in a dry, ventilated area.

2: Connect fittings supplied with the pump to the vessels plumbing. (Figure 4). Use hose clamps on the slip on barb hose connectors.

Important: Install strainer pump inlet to protect valves from debris.

3: Fasten pump to a flat surface. If mounting vertically; install with pump head down



Jabsco Par-Max PLUS pressure pump installationDo not over tighten screws to allow rubber mounts to absorb vibration.

4: Install inlet and discharge fittings. Firmly push slide clips  forward to lock fittings in place. – Figure 5

Allow the pump to prime with the discharge line (or spray valve) open to avoid airlock. The built-in pressure switch will shut off the pump automatically when the discharge valve is closed and will restart the pump when the valve is opened. If the pump runs out of liquid, it will continue to operate. Running dry will not damage the pump. Turn the pump off manually.


Accessories (not included)

Accumulator Tanks

Jabsco accumulator tanks used in pressure pump systems

Accumulator tanks hold a reservoir of air and water down stream from the pump. The air acts as a cushion, absorbing pump and pressure fluctuations, smoothing the flow and making the system quieter. Accumulators allow the pump to reach shut-off pressure more smoothly which reduces the on/off cycle which gives better control of hot water delivery.
Our accumulator tanks all have a bladder that separates water from air. The bladder is pre-pressurised but may need fine tuning when installed to give the most efficient performance. One of the advantages of an accumulator tank is that they can dispense up to half of their capacity of water even when the pump is switched off. So the bigger the reservoir, the more water you have available without having to switch the pump on helping you wash your hands or clean your teeth without noise.


Jabsco Water Pressure Regulator

Water Pressure Regulators

Inlet water regulators are designed to protect your boat water system plumbing and fixtures from the possible high pressure of municipal water systems. Regulation is controlled at all flow rates by a pre-set spring and removable strainer traps debris. Both inline portable and permanent flush mount models are available in our new line of diaphragm sealed regulators.

PumpGardTM Strainers
Inlet Strainers are an essential part of any fresh water system using a diaphragm pump – protecting the valves from small particles in the water. Our Pumpgards™ have been designed for easy installation
and rapid filter screen cleaning having a transparent bowl that screws off to allow simple, regular inspection.
