Product Overview

The 30 lb Pressure Relief Valve for Caretaker 5-Port Water Valve | 1-1-220 is an essential safety and protection component for compatible Caretaker in-floor pool cleaning systems.

This pressure relief valve is designed to open when system pressure exceeds approximately 30 PSI, helping relieve excess pressure within the Caretaker valve and connected plumbing. It helps protect the water valve, pump, filter, and associated pool plumbing from pressure buildup that may occur if flow becomes restricted or manual valves are accidentally closed.

This part is commonly used with Caretaker 5-Port Water Valves and compatible Zodiac / Jandy Caretaker, EnvironPool, and Dust&Vac in-floor cleaning systems.

Ideal For

• Caretaker 5-Port Water Valve systems
• Zodiac / Jandy Caretaker in-floor cleaning systems
• EnvironPool in-floor cleaning systems
• Dust&Vac in-floor cleaning systems
• Replacing worn or leaking pressure relief valves
• Protecting water valve and plumbing components
• Preventing excess system pressure buildup
• Pool service repairs and safety maintenance
• In-floor pop-up cleaning system equipment pads
• Professional pool maintenance and system troubleshooting

Benefits

A working pressure relief valve is critical for protecting a Caretaker in-floor cleaning system. If pressure rises too high, the valve helps relieve that pressure before it can damage the water valve, plumbing, pump, filter, or other connected equipment.

This replacement valve is especially important if the existing valve is leaking, stuck, missing, cracked, or no longer opening properly. Replacing a faulty pressure relief valve can help maintain safer system operation and reduce the risk of expensive repairs caused by pressure buildup.

For pool service professionals, this is a smart replacement part to keep available when servicing Caretaker 5-port in-floor cleaning systems.

Specifications

Included Components

• 1 × 30 lb pressure relief valve

Note: Water valve assembly, pressure gauge, cup strainer, O-rings, clamps, unions, plumbing fittings, and other Caretaker valve parts are sold separately unless otherwise stated.

Installation Notes

Turn off the pool pump and relieve system pressure before removing or replacing the pressure relief valve. Make sure the system cannot restart during service.

Inspect the existing valve, union fitting, plumbing, and surrounding components for cracks, leaks, restrictions, or damage. Install the replacement relief valve in the correct fitting location and verify that it is secure before restarting the system.

After installation, restart the pool system and check for leaks. If the pressure relief valve opens frequently, this may indicate a system issue such as a clogged cup strainer, restricted plumbing, dirty filter, closed valve, worn internal valve parts, or malfunctioning gear assembly. The cause of high pressure should be diagnosed before continued operation.

Professional installation and troubleshooting are recommended.
