Product Overview

Help keep pool or spa water moving in the intended direction with the Pentair FullFloXF Check Valve. Part 263060 is a straight, two-port check valve that allows forward flow and closes to help prevent reverse flow when conditions change.

The CPVC valve accepts 2½-inch pipe inside its ports or 3-inch slip fittings over the outside of its ports. Its clear cover lets a service professional inspect the flapper and flow direction. It is suited to compatible pool and spa plumbing systems where backflow prevention is needed.

Installation and Replacement Guidance

Check the flow-direction marking on the valve before installation. A check valve must be oriented so normal system flow opens the flapper. Verify the pipe size, fitting type, and space available around the valve for future service.

The 2½-inch and 3-inch sizes describe alternative connections on the same ports. They do not mean the inlet is 2½ inches and the outlet is 3 inches. Shut off the pump and relieve system pressure before working on the plumbing. Professional installation is recommended.

Customer-Facing Q&A

Q: Is part 263060 the same as the Pentair 263059 diverter valve?
A: No. 263060 is a check valve that operates automatically to help prevent reverse flow. 263059 is a manually operated two-way diverter valve used to control flow.

Q: Does this valve need an actuator?
A: No. The check valve opens and closes in response to water flow; it does not use a valve actuator.

Q: Can I use it with 3-inch plumbing?
A: Yes, its ports have a 3-inch slip connection on the outside. Confirm the fittings and installation layout before ordering.
