NP Plus (NPP) flow centers have Flo-Link double O-ring connections to allow the flow center to be easily connected to the heat pump. The NPP includes an additional insulated 3-way valve to allow the ground loop to be flushed separate from the heat pump. One of the hose kits below may be used to provide simple and flexible plumbing. Flo-Link adapters may be used if hard piping. For example, Flo-Link x 1-1/4” PVC glue adapters (part # 3425) are available for PVC schedule 80 piping to the heat pump. See Hose Kit section and Flo-Link fitting section for other options.
