AquaCal Heat Pump Bypass Manifold | STK0135
AquaCal heat pump bypass manifold, STK0135
Routes part of the water around the heat pump, so the flow through it stays inside AquaCal's limits when the pool pump moves more water than the heat pump wants. Genuine AquaCal, part number STK0135.
- The factory part. Made by AquaCal for AquaCal equipment, not a one size fits most substitute.
- Matched before it ships. Send us the model and serial number from your heat pump's data plate and we will confirm the fit.
- Pump off first. Turn the pool pump off and close the valves before opening the plumbing at the heat pump.
The part that fits the first time.
Send us the model and serial number from the data plate, or a photo of the old part, and we will match it before it ships.
