Fill the grease cap on gray models with Magic Lube or similar lubricant annually. Newer valves, known as Never-Lube, do not need to be manually lubricated. Important to keep older combination valves lubricated with a Teflon or Silicone lubricant. You can loosen the lock nut and lift the handle about halfway to turn the valve past the shut off stop. However, deadheading the valve can be useful to block water flow when the pump is off, for repair or maintenance on the pump, filter or plumbing. Be careful not to accidentally dead head the valve, blocking incoming water flow into the port marked ‘Inlet”. This results in 25% flow from the drain, and 75% flow from the skimmer.ģ way or combination valves have a tab on the underside of the valve handle designed to limit the range of motion to 180 degrees. In most cases, the valve is turned to halfway close off the main drain, while the skimmer pipe is fully open. A simple pool may have one 3-way valve installed in front of the pump, to control the flow from the skimmer and main drain. In effect a 3-way valve operates as a Tee fitting, with adjustable flow rates to or from each pipe attached to the valve. One pipe can be completely or partially closed off, while the other port is fully open, or both ports (pipes) can be fully open at the same time. The design of the valve, allows you to easily control the flow from two pipes with one valve. As you turn the valve handle, the diverter inside rotates in the same direction. Wherever the curved front of the handle is located, so will be the 'door' of the valve. Notice in the diagram that the size and curve of the handle (#3) corresponds exactly with the size and curve of the diverter (#8) inside the valve body. What can be confusing for combination valve users is what is happening inside the valve when they turn the handle.

Another advantage of these valves is that you can plumb with pipe to the inside of the valve, or you can glue a coupling to the outside of the valve port, allowing you to plumb 1.5' or 2' with the same valve. The 3-way design (shown) allows for plumbing flexibility and simplicity, and the valve is also available in a 2-way design. These valves can handle flow rates in excess of 150 gpm, with minimal resistance, and pressures up to 50 psi.Ī removable lid makes these pool valves serviceable in the event of a clog or the breakage of internal parts. 3-way valves are also easier to use than other types of pool valves and newer models require no lubrication. Jandy valves are more expensive than ball valves, but their design allows one valve to replace two ball valves, making plumbing simpler and cleaner. Robert Ortega, working for Purex was the first to patent a 3-way pool valve in 1980, but it didn’t catch on until Jandy introduced their first model, which was white in color. You can usually identify the manufacturer of a ball valve by it's handle.The most common variety of valve found on pool plumbing is a 3-way valve, popularized by Jandy, and copied by Compool, Hayward and CMP.

The thread is 1/8' NPT and you can use a brass or plastic plug and buy the entire new Jandy valve and pull out the entire assembly from the body and install it into the existing valve. You can buy the diverter kit that converts the valve to a NeverLube and includes a red plug to go in the grease cap hole or you can buy a replacement grease cap. Replacing Broken Grease Plug in Jandy Grey Diverter Valve The original plastic threads will be damaged unless the threads match exactly. The screw threads are different for different manufacturers and the screws will not go into the same threads.

When installing an actuator, use the same manufacturer as the valve.

Crossthreading will ruin the threads quickly.

When installing the screws, turn the screw counterclockwise until it drops into the original threads and then go clockwise to tighten.

Tips on Preventing Stripped Screws on Diverter Valves

You do have to make sure not to let the epoxy set above the top of the screw hole.įill both holes completely with putty and let dry, then drill a pilot hole and then create new threads with the screw.
