Three Way Diverter Valves

Three way valve installed

Three way diverter valves are recommended for greywater systems:

The only systems I design without diverter valves are for the simplest homes which don't have a septic or sewer to divert to.

Three way valves work better than the alternatives (two ball valves, movable pipe sections...) in that their proper operation is more obvious, and that they don't clog as readily.

Jandy Never Lube Three Port Valves are the greywater industry standard. Besides being well-made and guaranteed never to leak or break, they have the huge advantage that you can unscrew the face plate and turn it to make any of the three ports the "inlet."

The face plate can also be removed for cleaning out the valve or to snake any clog nearby.

They last a long time. We suggest you use no hub connectors or glue them with silicone sealer so they can be reused if you want to change the geometry of your plumbing in the future.

The valves can be operated remotely and/or automatically with a $249 Jandy 24v actuator (we don't handle these).

Each valve fits two pipe sizes; one on the inside and one on the outside. The larger valve is recommended for two inch pipe. Rated to 200 psi. Jandy model numbers are 4715 for smaller valve, 4717 for larger one.
