1 Liter RV Water Pump Accumulator Tank 125 PSI, Pre Pressurized Design for Camper, Boat, RV Systems

PrePressurized Accumulator, 1L — PA Plastic Overview This prepressurized accumulator smooths water flow and stabilizes pressure in pressurized systems. Precharged to 10 PSI and designed for direct installation, it reduces pump cycling, decreases noise, and helps protect pumps and fittings from pressure spikes. Key Specifications Item type: Pre Pressurized Accumulator Material: PA plastic Size: Approx. 30 x 14.4 cm (11.81 x 5.67 in) Volume: 1 L (33.8 FL.OZ) Charging pressure: 10 PSI / 0.7 BAR Maximum operating pressure: 125 PSI / 8.6 BAR Air fill valve: Standard car tire valve Inlet/outlet diameter: 1/2 in MNPT Main Benefits Stabilizes water pressure: Absorbs pressure spikes and prevents rapid fluctuations for smoother flow at taps and showerheads. Reduces pump cycling: Stores peak line pressure so pumps run less often, extending pump service life and lowering noise from frequent starts. Protects system components: Cushions against sudden pressure changes that can loosen fittings or stress pipes. Easy to install and adjust: Precharged for most systems and simple to set to 3 PSI below the pump switch for operation. Included in the Package 1 x Pump body 2 x Nut joint 2 x Hose clamp 1 x PTFE tape 1 x Instruction manual Compatibility and Use Compatible with most RV pumps and pressurized systems within the 10 PSI to 125 PSI range. Precharged to 10 PSI and suitable for RV, marine, food, and other liquid systems where pressure stabilization is needed. Recommended pressure adjustment: reduce accumulator air pressure to about 3 PSI below the pump switch setting for performance. Typical Applications and Scenarios RV fresh water system: Absorbs excess heatrelated expansion in water lines and prevents the sudden pop sound when faucets are opened. Leaky or aging plumbing in mobile homes or boats: Reduces frequent pump startups caused by small drips or loosened fittings, helping maintain steady pressure between pump cycles. Showers and faucets with uneven flow: Minimizes pulsation from irregular pipe or nozzle flow for a more consistent showering experience. Installation Notes Direct installation using the included fittings and hose clamps. Use a standard air pump and pressure gauge on the car tire style valve to set the accumulator air charge. Follow the provided instruction manual. Set air pressure approximately 3 PSI below the pump switch point for reliable operation. This prepressurized accumulator offers a compact, practical solution for improving water system stability, reducing pump wear, and delivering smoother water flow in a variety of pressurized systems.
