An autofill hides the most obvious sign of a leak, a dropping water level, by topping up the pool around the clock. The remaining signs are indirect: a water bill that rises for no clear reason, chemical levels that will not stay balanced because fresh water keeps diluting them, a fill valve that seems to run constantly, algae in a pool that used to stay clear, or wet ground and soft spots that never dry.
To check, turn the autofill off for 24 hours and do the bucket test. If the pool level drops more than the bucket level, the autofill has been hiding a leak.
