Wellntel Sounder Probe 4

Next generation replacement sounder to improve reliability and signal quality.

What Does It Offer?

Replacement for water-impaired or otherwise compromised sounder system.


If the sensor is powered by AC, unplug the adapter from the outlet. Open the sensor and disconnect the battery (or AC power adapter) and PPK wires from sensor. Twist the sensor off the well at the vent or nipple. Remove the vent or nipple and inspect the port for clean, smooth edges. Unscrew the old sounder from the sensor, and replace with this one. Carefully feed the sounder through the vent or nipple, taking care not scratch or tear the sounder probe on the way in the well.


Wellntel warrants that the product will be free from defects in materials and workmanship for a period of one (1) year from the date of delivery.
