Product details
This is the Raypak 017155F flow sensor for the E3T pool heater. It is the genuine Raypak OEM part rather than an aftermarket equivalent.
What it does
A pool heater needs to know that water is moving through it before it fires. The flow sensor supplies that signal. When the sensor fails or reads poorly, the heater can refuse to start even with the pump running normally, which sends a lot of people looking at the pump before they look at the sensor.
Before ordering
Confirm the part number against your heater. This sensor is listed for the E3T, and Raypak uses different sensors across its heater lines.
