Product Description
Ensure reliable water pressure and quieter operation with the Jabsco 1 Litre Accumulator Tank with Internal Bladder (Model 30573‑0000). Designed for marine and RV pressurised freshwater systems, this tank minimises pump cycling and pressure fluctuations, delivering a consistent flow from taps and showers.
The internal nitrile bladder (membrane) separates air and water, absorbing pressure spikes and maintaining system stability. Pre-charged to 10 psi (0.7 bar) at the factory, it can be adjusted to suit your pump’s cut-in pressure using the integrated Schrader valve.
Constructed from durable, corrosion-resistant materials, the 1 L tank is compact and can be installed in any orientation. Multiple connection options are included for straightforward setup. This ensures quieter, more efficient water systems, reduces pump wear, and extends the lifespan of your equipment.
Ideal for marine, caravan, and RV applications, the Jabsco accumulator tank is a reliable upgrade to any freshwater system, providing smooth, even water flow and longer pump life.
