Product Overview

The Blue Square In-Floor Water Valve with C5 Valve Adapter Kit | 1145110 is a replacement and conversion solution for older Caretaker 1.5" 5-port and compatible A&A 5-port in-floor water valve systems. This kit is designed to modernize outdated in-floor cleaning valve setups by adapting them to Blue Square’s Q360/R360-style valve platform.

The C5 adapter configuration is made for 5-port in-floor pool cleaning systems with 1.5" plumbing. It helps direct water flow to each cleaning zone in sequence, allowing pop-up heads to clean the pool floor, steps, benches, and other programmed areas with improved consistency.

This kit is ideal for pool professionals replacing aging Caretaker-style valves that no longer cycle properly, leak, lose pressure, or fail to distribute flow evenly across cleaning zones.

Ideal For

• Replacing Caretaker 1.5" 5-port water valves
• Replacing compatible A&A 5-port valve systems

• Blue Square Q360 / R360-style valve conversions
• Pools with 1.5" plumbing and 5 cleaning zones
• Restoring automatic zone sequencing
• Improving pop-up head performance
• Equipment pad valve upgrades
• Pool remodels and system modernization
• Professional pool service and repair work

Key Features

• C5 valve adapter configuration — designed for 5-port Caretaker-style in-floor valve replacement applications.
• Replaces Caretaker 1.5" 5-port valves — ideal for upgrading outdated Caretaker in-floor cleaning systems.
• Compatible with A&A 5-port valve replacement applications — supports compatible 5-port A&A-style retrofit installations.
• 1.5" plumbing application — made for systems using 1.5-inch valve plumbing.
• Water-powered valve operation — automatically cycles cleaning zones using pool system water flow.
• Supports Q360/R360-style performance — used as part of Blue Square’s updated in-floor valve platform.
• Helps maximize water flow — designed to provide strong flow with minimal pressure variation between zones.
• Improves zone consistency — helps pop-up heads operate more evenly across the pool.
• Retrofit-friendly design — helps convert existing in-floor systems without abandoning the current cleaning zone layout.
• Professional-grade replacement kit — intended for pool service technicians, builders, and renovation specialists.

Benefits

The Blue Square 1145110 Water Valve with C5 Adapter Kit helps bring older in-floor cleaning systems back to life. When a Caretaker-style valve becomes worn, inefficient, or unreliable, cleaning zones may stop rotating correctly, pop-up heads may lose pressure, and debris may collect in dead spots.

This replacement kit helps restore automatic zone sequencing and supports smoother water distribution across the system. By improving flow consistency, the valve can help the pool’s in-floor heads clean more effectively while maintaining better circulation throughout the pool.

For many older systems, this kit provides a practical upgrade path without requiring a full in-floor cleaning system replacement.

Specifications

Included Components

• Blue Square Q360/R360-style water valve assembly
• C5 5-port valve adapter kit
• Plumbing template or adapter layout components, depending on packaging
• Required adapter components for compatible 1.5" 5-port Caretaker-style conversions

Note: Additional plumbing fittings, reducers, couplings, O-rings, clamps, or repair components may be required depending on the existing equipment pad layout and condition.

Installation Notes

This product is intended for professional installation by a pool technician familiar with in-floor cleaning valve systems. Before installation, confirm that the existing valve is a Caretaker 1.5" 5-port or compatible A&A 5-port water valve setup.

Turn off all pool equipment and relieve system pressure before removing the old valve. Check the existing plumbing layout, pipe size, zone count, valve position, and clearance around the equipment pad. After installation, the system should be tested to confirm proper zone rotation, pop-up head movement, water pressure, and leak-free operation.

If the existing in-floor system has weak cleaning performance, inspect the pump flow, filter pressure, pop-up heads, valve internals, and plumbing restrictions before completing the conversion.

Customer-Facing Q&A

Q: What does the Blue Square 1145110 replace?
A: It replaces Caretaker 1.5" 5-port in-floor water valves and compatible A&A 5-port valve applications.

Q: What is the C5 adapter used for?
A: The C5 adapter is used to convert compatible 5-port Caretaker-style valve systems to Blue Square’s Q360/R360-style valve platform.

Q: How many ports does this valve kit support?
A: This kit is designed for 5-port in-floor cleaning systems.

Q: What plumbing size is this for?
A: It is designed for 1.5" plumbing applications.

Q: Does this require electricity?
A: No. The valve operates using water flow from the pool system.

Q: Is this used for pop-up in-floor cleaning systems?
A: Yes. It is used with in-floor pool cleaning systems that rotate water flow through pop-up cleaning zones.

Q: Can this improve cleaning performance?
A: Yes. Replacing an old or failing valve can help restore zone rotation, water flow, pop-up pressure, and cleaning consistency.

Q: Is this a complete in-floor cleaning system?
A: No. This is the water valve and C5 adapter kit only. In-floor heads, nozzles, bodies, pumps, plumbing, and other system parts are sold separately.

Q: Will this fit Paramount 6-port systems?
A: No. This C5 kit is for 5-port Caretaker/A&A-style applications. Paramount 6-port systems require a different adapter kit.

Q: Should this be professionally installed?
A: Yes. Professional installation is recommended because the kit must be matched to the correct valve layout, plumbing size, and cleaning zone configuration.
