Jabsco Mini Accumulator Tank — NSF Listed, Food-Grade
The most compact accumulator tank in the Jabsco lineup — and the only one in the catalog manufactured from NSF Standard 18 listed, food-grade materials. The Jabsco 30573-0003 installs in any pressure-switch-controlled freshwater system to reduce pump cycling, smooth out diaphragm pump pulsing, and improve hot/cold temperature control with instant water heaters. Quick-connect fittings make it easy to add to a new or existing system, and the built-in mounting point for an optional pressure switch gives you the flexibility to relocate the switch to the tank for a cleaner installation. Internal bladder separates the air charge from system water.

Parts Desk Insights
Choose the Mini over the 33 oz Jabsco tank when space is the primary constraint, when NSF food-grade certification is required for your installation, or when you want the option to mount the pressure switch directly on the tank. The pressure switch mounting point is a practical feature for clean installations where you want to consolidate components. For more pressure storage capacity, the Jabsco 33 oz Pressurized Accumulator Tank is the step-up option in the Jabsco lineup, and the GROCO PST-1 Pressure Storage Tank is the full-size, high-capacity option rated to 100 PSI. Compatible freshwater pumps include the Jabsco Par-Max 1 GPM, Jabsco Par-Max 2 GPM, Jabsco Par-Max 3 GPM, and the SHURflo Aqua King II 2.0 GPM.
