Home Improvement pump built to keep water flowing where mains supply is absent, aimed at low-voltage setups. Peace of mind for mobile owners comes from straightforward 12V compatibility and a design focused on steady delivery for basic taps and showers. Will the Jabsco Par-Max 3 Water Pressure Pump suit a caravan or small boat water system?
⚡ At a Glance
- • Flow Rate: Delivers steady flow suitable for light domestic and mobile water use
- • Best for: Owners of caravans, small boats or off-grid setups needing compact water supply
- • Not ideal for: Large households or systems requiring high-pressure, high-flow performance
Compact pump intended for low-voltage water delivery in mobile or isolated installations. Designed to meet modest domestic or marine water supply needs.
Reliable outlet pressure - with a 25 PSI pressure rating
A 25 PSI rating represents the pump's maximum nominal outlet pressure, established by its internal pressurisation mechanism and pressure switch. That rating helps the pump maintain consistent pressure under typical light loads.
Maintains steady tap pressure for single-sink use and short showers, reducing pressure dips during routine tasks.
Simple 12V integration - thanks to low-voltage operation
Designed to run from a 12V DC supply, compatible with vehicle, marine or leisure battery systems without requiring an inverter. Electrical connections follow common 12V wiring practices for ease of installation.
Allows direct connection to on-board batteries in caravans and boats, avoiding complex power conversions.
Adequate flow for light use - with a 3 GPM flow rate
A 3 GPM (gallons per minute) flow rating indicates modest throughput suited to single outlets or intermittent shower use. Pump performance matches low to medium demand cycles rather than continuous heavy-duty operation.
Supports routine washing and short showers without overtaxing the system, making it suitable for solo or small-group mobile use.
