Why Are My Sprinklers Running in the Rain?

If your sprinklers are operating during steady rain, first determine how the system is supposed to detect wet weather.

Traditional rain sensors

A wired or wireless rain sensor may be bypassed, damaged, disconnected, or not yet wet enough to trigger its threshold.

Smart weather-based controllers

Controllers that rely on internet weather data need the correct location, connectivity, and weather settings.

Manual watering can override normal behavior

Some manual-start functions run regardless of the normal schedule or weather adjustment.
