Xylem 305730004A Accumulator Tank 21 oz Marine Water System

The Xylem 305730004A is a compact 21-ounce accumulator tank designed to reduce pump cycling and maintain steady water pressure in marine and RV water systems. This pneumatic bladder-style accumulator absorbs pressure fluctuations, extending pump life and providing smoother water flow throughout your vessel or vehicle.

Key Specifications:

• Working water volume: 21.5 ounces
• Compact dimensions: 5 inches diameter x 9 inches height
• Dual connection options: 1/2 inch hose barb and 1/2 inch-14 NPT threaded port
• Maximum operating pressure: 125 PSI
• Pre-charged pressure: 10 PSI
• Durable pneumatic bladder construction

The straight-port configuration and multiple connection options make installation flexible for tight spaces. The pre-charged bladder is ready to install and helps minimize water hammer while reducing the number of pump starts, which decreases energy consumption and mechanical wear. Ideal for galleys, heads, and washdown systems on boats, or freshwater systems in RVs and campers.
