Jandy R0556900 – 0-60 PSI Pressure Gauge for Cartridge Filters
Product Overview
The Jandy R0556900 is a genuine replacement pressure gauge designed for use with compatible cartridge filter systems. It provides accurate monitoring of filter tank pressure (up to 60 PSI), helping you maintain optimal system performance and detect when service is required.
Key Features
- Measures 0-60 PSI pressure range for pool filter tanks.
- Bottom-mount ¼″ MPT connection for secure plumbing fit.
- Direct replacement for Jandy CJ/CS series cartridge filters and other compatible systems.
- Simple to install—twist out old gauge, apply thread sealant or Teflon tape, and hand-tighten new gauge.
Technical Specifications
- Part Number: R0556900
- Dial Range: 0 to 60 PSI
- Connection: ¼″ MPT bottom mount
- Applicable Equipment: Cartridge filters (CS/CJ series or equivalents)
Installation Instructions
- Turn off the pump and relieve pressure in the filter system.
- Remove the old gauge from the filter housing or adapter port.
- Apply thread sealant or approved tape to the ¼″ MPT threads of the new gauge.
- Screw the new gauge into place and tighten until flush—do not over-tighten.
- Restore the system, run the pump, and check that the gauge reads correctly under normal operating pressure.
Troubleshooting
-
No pressure reading: Verify the pump is circulating, the filter tank is closed and the gauge is installed in the correct port.
-
Gauge does not move or reads erratically: Ensure there is no debris or blockage into the gauge port, and that the gauge housing is not damaged.
-
Leaks at gauge fitting: Remove gauge, reapply thread sealant or tape, and ensure proper torque when reinstalling.
Maintenance Tip
Check the gauge reading each time you service the filter. Replace the gauge if the pointer sticks, the dial face fogs, or if the reading appears inconsistent compared to past clean/tank routine benchmarks. An accurate pressure gauge helps you decide when backwashing or cleaning is needed—saving time and prolonging equipment life.
