The Jabsco 31670-0094 dual-stage fresh water pressure system delivers automatic, on-demand flow using two Par-Max 4 quad diaphragm pumps in one compact assembly. An integrated 1 liter (33 fl oz) accumulator tank smooths pressure, reduces cycling, and improves shower temperature stability, while pre-installed filters, hoses, and plumbing connections simplify installation. The system provides up to 7.5 GPM (28.4 LPM) for as many as 6 outlets with 24V operation, a 20 PSI cut-in and 40 PSI cut-out pressure switch, 3/4 inch hose ports (20 mm), self-priming up to 1.5 m (5 ft), and ignition-protected motors with thermal overload protection.

Jabsco 31670-0094 Dual-Stage 24V Fresh Water Pressure Unit
The Jabsco Dual Max system combines two automatic diaphragm pumps with an accumulator tank to deliver smooth, reliable fresh water pressure for multi-outlet installations. It switches automatically between low and high demand operation to provide efficient flow with reduced cycling, helping minimize noise and water hammer while improving hot water temperature control.
Application
- Designed for boats and RVs with multiple outlet fresh water systems
- Suitable for up to 6 outlets
- Automatic operation: runs when a faucet is opened and stops when it is closed
