The Pool Sentry Water Level Control maintains water levels on leaky pools or unattended pools during vacation periods. It also provides ideal pump protection against burnout. No installation required, simply attach a hose. This is the newest m-3000 model of The Pool Sentry Water Level Control. Pool water evaporates every day and The Pool Sentry will keep your water level up without over-filling.

When the hot weather causes your pool to evaporate, the Pool Sentry auto pool fill device lets you stop filling your pool manually and make better use of your time.
