Accessories 

Accumulator Tanks (not included)

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-pressurized 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.

Water Pressure Regulators (not included)

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 (included)
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.
