Groco PST-2 1.4 Gallon Pressure Storage Tank

The Groco PST-2 is a 1.4-gallon pressure storage tank designed to optimize freshwater system performance on boats and marine vessels. This pneumatic accumulator tank features a durable rubber bladder that separates the air charge from the system water, preventing waterlogging and extending pump life.

Key Features:

• 1.4-gallon capacity provides optimal pressure storage for marine freshwater systems
• Pneumatic pressure charge matched to pump cut-on pressure for consistent performance
• Internal rubber bladder separates air charge from water, eliminating waterlogging issues
• Delivers smooth, consistent water pressure throughout the system
• Maintains even temperature mix in showers and faucets
• Reduces pump cycling, extending pump motor life and reducing noise
• Corrosion-resistant construction for reliable marine environment performance

This pressure storage tank installs inline with your freshwater pump system and helps reduce the short-cycling that occurs when faucets or fixtures are partially opened. By maintaining steady pressure, the PST-2 improves comfort and protects your investment in pumping equipment.
