Product Overview
The Jandy R0556900 Pressure Gauge Replacement Kit is a genuine Jandy / Zodiac replacement gauge designed for select Jandy CS and CJ Series cartridge filters. This pressure gauge helps monitor filter system pressure so pool owners and service technicians can identify when the filter needs cleaning, cartridge maintenance, or system troubleshooting.
Designed with a 0–60 PSI pressure range and bottom-mount connection, this replacement gauge is a practical repair part for restoring accurate pressure readings on compatible Jandy cartridge filter systems. A working pressure gauge is important for maintaining proper filtration performance and protecting pool equipment from unnecessary strain.
Ideal For
This pressure gauge kit is ideal for pool service technicians, maintenance professionals, and pool owners replacing a damaged, leaking, unreadable, or inaccurate filter pressure gauge. It is commonly used during filter maintenance, cartridge replacement, and pressure-related pool system diagnostics.
Key Features
Genuine Jandy / Zodiac Replacement Part
Designed as an OEM replacement pressure gauge for compatible Jandy filters. Using the correct manufacturer replacement part helps ensure proper fit, reliable readings, and compatibility with the intended filter models.
0–60 PSI Pressure Range
Displays filter pressure from 0 to 60 PSI for routine system monitoring. This helps users track normal operating pressure and identify when filter cleaning or service may be needed.
Bottom-Mount Gauge Connection
Features a bottom-mount threaded connection commonly listed as 1/4" MPT. This design fits compatible Jandy CS and CJ Series cartridge filter applications.
Helps Monitor Filter Performance
A working pressure gauge helps indicate changes in water flow and filter condition. Rising pressure can signal dirty cartridges or restricted flow, while unusually low pressure may indicate suction issues, air leaks, or pump-related problems.
Simple Replacement Component
This is a replacement pressure gauge only, not the complete filter or air relief assembly. It is a straightforward service part for replacing a worn or failed gauge.
Benefits
The Jandy R0556900 Pressure Gauge Replacement Kit helps restore accurate pressure monitoring for compatible cartridge filter systems. Accurate pressure readings make it easier to know when to clean or replace cartridges, inspect plumbing restrictions, and maintain proper pool circulation.
Replacing a faulty gauge can help prevent unnecessary service calls, improve maintenance timing, and support longer filter and pump life. For best results, always turn off the pump and relieve system pressure before removing or installing the gauge.
