6560-857 | Flow switch W/Transparent Tee Fitting for 1 Pump

Had an issue with my Caldera spa where the water would not heat up, and I had suspected it was the flow switch due to the "blinking" temperature light on the main panel. While the caldera spa uses a heater with a built-in flow switch, I was fortunate enough that it still used a separate signal to the main board. I was able to avoid having to purchase a brand new heater kit, and instead put this inline after the heater and plugged it right into the flow switch header on the Caldera main board.Been running about a year now and no issues!

Solved the problem with my heater that had a bad pressure switch - I saved hundreds of dollars with this product!!

I was able to use this instead of replacing the heater with integrated pressure switch. Huge savings.

Nothing

Was the same switch as I needed to repair my hot tub. Way more cost affective than the factory part and was the same part.
