Tax included Shipping calculated at checkout.


An essential part of installing a pool or spa heat pump, this valve installation kit includes Two 3-Way 40/50mm Valves. 40mm pipe glues inside or 50mm sockets glue outside.

This allows you to set the correct bypass flow through the heat pump to achieve the 2-3° differential between Inlet & Outlet, as required by most heat pump manufacturers. 

Comes with Hayward/Jandy/CMP 2x 40mm or 2x 50mm 3-way valves & 1x 3-way valve.


  • One-speed Standard Pumps:  Set valves for a 2-3° differential.
  • Two-Speed Pumps: Set the 2-3° differential temperature based on low-speed.
  • Variable-Speed Pumps: Find what speed your pump is set to when heating, then set the valves for the 2-3° differential.
