Valves
On Pipes
Diverter Valves
Motorized Valve Actuators can be screwed on top of a diverter valve for a pool automation system to change the valve position.
Jandy
Jandy has two lines of high quality diverter valves - Grey and Never Lube. Both types of valves work the same way. The Grey valve has a grease cap that can be lubed without any dis-assembly. The Never Lube Valve is completely maintenance-free.
The valves come in 2 port and 3 port models. Both models are available in 1.5" x 2" and 2" x 2.5" sizes. The Never Lube is also available in 2.5" x 3" size.
This Jandy Parts Catalog has a complete list of valves and replacement parts.
Pentair
Pentair diverter valves are lube-free and never require lubrication. There are 2-way and 3-way models that accepts 1 1/2 in., 2 in., and 2 1/2 in. slip outside PVC plumbing.
Pentair diverters have a Fiberglass reinforced handle and can withstand pressure up to 150 psi.
Hayward
Hayward has 2-way and 3-way diverter valves in 1.5" x 2" and 2" x 2.5" sizes in CPVC and PVC materials.
Ball Valves
You can usually identify the manufacturer of a ball valve by it's handle.
Jandy has a line of Gold Standard Ball Valves with 1 1/2' and 2" with unions and 3/4' to 4" without unions.
Praher has a line of ball valves.
Repairs
You can buy new insides for the praher valves, easy swap out. You may need to buy an identical valve and use the internals.
Knife Gate Valves
Check Valves
Flapper Check Valves
Swing Check Valves
Spring Check Valves

Thread Types
There are confusing three letter and four letter acronyms that describe the type of threads on a fitting. The correct threads needs to used for screw in fittings to have a tight, strong, and leak proof connection. Common yypes used in pool plumbing are:
- S- generally means a slip fitting that is not threaded and must be glued
- FPT - female pipe thread.
- MPT - male pipe thread
