Shurflo by Pentair Pre-Pressurized Accumulator Tank - 24 oz.

The Shurflo by Pentair Pre-Pressurized Accumulator Tank – 24 oz. is purpose-built for RV, marine, and off-grid water systems where reliable pressure stabilization is essential. Installed downstream of your pump, this compact accumulator tank eliminates the nuisance of pump cycling, reduces pressure pulsation, and protects against dangerous pressure spikes that can damage plumbing connections and appliances. Whether you're outfitting a travel trailer, mobile home, or remote cabin water supply, this tank extends pump lifespan while reducing unnecessary battery drain on 12V or 24V systems.

Built by Pentair's Shurflo brand—a trusted name in demand-activated water pumps—the pre-pressurized design uses a patented domed chamber that maintains consistent system pressure without requiring field calibration. The 24-ounce capacity strikes an optimal balance between space efficiency and surge absorption, providing enough volume to dampen pressure spikes while remaining compact enough for tight installations. The robust construction handles the demands of intermittent or high-draw applications, making it ideal for systems where shower, toilet, and faucet use happens in quick succession.

This accumulator tank pairs seamlessly with Shurflo pump systems (12V, 24V, and 115V models) commonly found in motorhomes, trailers, boats, and emergency backup water supplies. Installation is straightforward—simply position the tank between your pump discharge and the pressurized system line using standard plumbing fittings. Typical setups see a measurable reduction in pump start/stop cycles, quieter operation, and extended pump runtime on battery-powered applications. With a lightweight design (1.35 lbs) and compact footprint (6 × 5 × 11 inches), mounting under cabinets or in tight utility compartments is practical for most mobile or remote installations.
