GROCO Pressure Storage Tank - 3.2 Gallon Drawdown

The GROCO Pressure Storage Tank - 3.2 Gallon Drawdown (Model PST-3A) is a marine-grade accumulator tank designed for freshwater and pressurized water systems on cruising vessels, fishing boats, and live-aboards. Reliable water pressure is essential for any serious boater, whether for a galley, head, or deck wash system.

This tank stabilizes system pressure, reduces pump cycling, and extends the operational life of your pressure pump by absorbing demand spikes and maintaining consistent flow across multiple outlets. Built to GROCO's rigorous marine standards, the PST-3A features a 3.2-gallon effective drawdown capacity, ensuring smooth, uninterrupted water delivery.

Ideal for liveaboards, cruisers with multiple water consumers, and commercial fishing vessels, this accumulator tank is compact enough to fit in engine rooms, lazarettes, or under-galley cabinetry. Its internal bladder design separates pressurized air from potable water, maintaining system integrity and water quality.
