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.
