Tradie Pro Tip

When you're swapping out a water sensor, it's a good habit to give the whole water pan a thorough clean and check the float valve while you're in there. Scale and muck can build up quick and impact performance.

Pair With

Pair this water sensor probe with replacement evaporative cooler filter pads and a new float valve for a comprehensive annual service.
