GREENMILL Automatic Water Controller for Taps 3/4 inch-1 inch | Battery-Powered Irrigation Timer with LCD, Rain Delay, IPX4

Take the guesswork out of garden watering with the GREENMILL Water Controller, a battery-powered timer that mounts directly onto your outdoor tap and automates irrigation for one zone. Unlike basic mechanical timers, this controller offers precise digital programming with an easy-to-read LCD, flexible scheduling from 1 to 120 minutes, and a rain delay function to prevent overwatering. The included 1" to 3/4" reducer ensures compatibility with standard garden taps and hoses, while the IPX4 weather-resistant construction stands up to splashes and outdoor conditions. Powered by two AAA batteries, it requires no wiring or mains connection, making installation a breeze for any gardener.

In daily use

Set your watering schedule once and let the GREENMILL controller handle the rest. The intuitive interface lets you choose between daily, interval, or specific-day programming, so your lawn and plants receive the right amount of water at the right time. The rain delay function is a lifesaver during wet spells—simply activate it to pause watering for 24, 48, or 72 hours, then resume automatically. The manual override button gives you instant watering whenever you need it, without altering your saved schedule. The clear LCD shows all settings at a glance, and the low battery indicator alerts you well before power runs out.
