Jabsco Water Pump Par Max 4.0 HD 12 Volt Q401J-115S-3A 4.0 GPM 15.2 litre per minute 40PSI
These Heavy Duty (HD) Par-Max 4 freshwater pressure pumps offer robust construction and high performance. These new modern design pumps have a 4 chamber quad design pump head and offer pressure up to 60PSI. These heavy Duty (HD) models include a heavy duty wider diameter motor with a powder-coated shell, cast aluminium end bells and lower housing – to improve pressure capability and offer longer life and exceptional performance.
The ideal robust heavy-duty pump for providing freshwater automatically to up to 4 outlets on pleasure craft up to approx the 13 metre (40 Ft) range.
Includes a 40 mesh plug-in inlet strainer in the box with the pump.
HD Quad 4 chamber automatic pressure pump gives flow up to 4 US Gallons per minute (15.2 litres per minute) and pressure up to 60 PSI.
Serves up to 4 x 12mm outlets including galley, shower and additional faucet.
The Par-Max 4.0 HD gives very smooth water flow even at low demand due to its built-in pulsation dampening by-pass valve which controls unwanted cycling and reduces noise.
Inlet filter, corrosion-resistant motor, soft rubber vibration-dampening mounts and quick connect plug-in hose ports included – 2 x 12mm barbed for hose.

Electric Water Pumps The PAR-MAX Automatic Water System Pump is designed for self-contained boats and RV’s with multiple fixture water systems. The system operates automatically. When a fixture is opened, the pump instantly begins operation to provide a smooth constant flow from tank to faucet. Closing the faucet automatically discontinues pump operation.
The PAR-MAX pumps are self-priming and may be located above or below the fresh water tank in a dry location. To vertically mount these units, it is best to do so with the motor on top. This will prevent water dripping on motor in the event of a leak. Place pump on a solid surface and secure with four mounting screws (not included) being careful not to compress the rubber grommets which act as shock absorbers.
Select two of the port adaptors supplied to match your plumbing system. Flexible potable water hose or PEX tubing is recommended instead of rigid piping at pump. If you choose to use rigid piping, provide a short length of hose between pipe and the pump to avoid noise and vibration. Use clamps at both ends of hose to prevent air leaks into the water line. NOTE: Intake hose must be minimum 1/2″ (13 mm) ID reinforced hose. Main distribution line from pump outlet should also be 1/2″ (13 mm) ID with branch and individual supply lines to outlets no smaller than 3/8″ (10 mm). A Jabsco “Pumpgard” in line strainer should be installed between pump and tank to keep debris out of pump and system. Fresh water tank must be vented. Avoid any kinks or fittings which could cause excessive restrictions. Remember to periodically clean faucet and “Pumpgard” screens.
In an easily accessible location, install a switch (Jabsco 44960-Series) to control electricity to the pump. Turn the pump off when not used for extended periods or when the tank is empty. The electrical circuit should be protected with an overcurrent protection device in the positive lead. See chart for proper size. The pump circuit should not include any other electrical loads. The free lead at the pressure switch is positive. Black wire from the motor is negative. Select wire size from chart below. Use total length of wire from the battery to pump and return. Chart allows for 3% voltage drop. If in doubt, use next larger wire size.
