Aqua Select® Pressure Gauge ¼" Back Mount

For any pool filter (sand, cartridge, or DE) that requires a back-mounted pressure gauge, the Aqua Select^® Pressure Gauge will serve as a suitable replacement. This gauge accurately measures the pressure inside your tank, which steadily increases as the filter takes in more debris.

When the pressure of your filter has increased by 8 - 10 PSI from your starting pressure, it's time to backwash your filter or clean your cartridge.

Features:

• Replacement unit for pool filters that require a back-mounted pressure gauge
• Accurate measurements
