Jandy Two-Way Standard Grey Valves are for those that want a more economical pool/spa valve and don't mind the need to (possibly) lubricate the valve once in a while.
1.5" & 2" Jandy valves accept 1.5" pipe inside the port, or you can glue a 2" coupling around it.
2" & 2.5" Jandy valves accept 2" pipe inside the port, or you can glue a 2.5" coupling around it.
