Frequently asked questions
How do I identify the right replacement valve?
Valves are specified by port size, port count, connection type - slip, threaded or union - and body material. Measure the pipe outside diameter rather than guessing at nominal size, since PVC sizing does not match the physical measurement.
What is the part number for this valve?
Pro Series lists this valve under part number 7307. Quote 7307 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
Why is my valve leaking or hard to turn?
Stiff operation and weeping around the stem usually mean dried-out or chemically degraded seals. Many valve bodies can be rebuilt with a service kit rather than replaced outright, which avoids cutting into the plumbing.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Pro Series equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
Can I automate this valve?
Diverter valves in this style commonly accept a valve actuator so an automation system can switch them, but the actuator and its mounting hardware are separate items. Confirm the valve body is a type the actuator is rated to drive before ordering.
Is there a warranty on this valve?
It carries the standard Pro Series manufacturer warranty. The terms are set by Pro Series, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
