What it is

The Andrews 7703875 is a brass sensor pocket, also known as a sensor well, for Andrews water heaters. It houses a temperature sensor or thermostat probe, allowing the probe to be immersed in water without direct contact. This protects the sensor and helps maintain accurate temperature readings.

  • Water leaking from around the sensor pocket
  • Visible corrosion, cracking or damage to the brass body
  • Temperature readings fluctuating or inaccurate
  • Sensor probe loose within the pocket
  • Scale build-up on the pocket affecting heat transfer

Before you order

  • Confirm your appliance model matches the fit list above
  • Check the thread type and size of the existing sensor pocket
  • Ensure the sensor probe diameter is compatible with the pocket
  • Verify the part number 7703875 against your appliance's parts list
