Water timers are connected between the faucet and the sprinklers, opening and closing valves to control the water flow. Gradual-opening and closing valves are best, avoiding a "water hammer" bang that can damage pipes.

Popular brands include Gilmour, Gardena, Melnor and Nelson.

Countdown Timers and Flow Counters

These function like kitchen egg timers, counting down minutes (countdown timers) or gallons (flow counters). They can guard against forgetting to turn off the water: saving money and protecting against over-watering. Most are mechanical, driven by the water flow or a mechanical spring.
