Features: Single outlet electronic water timer, capable of delivering one or two watering sessions per day. Attached with a clear LCD screen for easy setup and operated by 2 x AA batteries (not included). Fitted with 3/4" hose connector and 3/4 BSP tap connector fixing directly on to the tap. Ideally suited for use with irrigation and sprinkler systems. Water timers save time, hassle and money from water bills. A mechanical timer is perfect for simple hose and sprinkler setups or perforated irrigation hoses. Just set the run time and put your feet up. The water will switch itself on when the time's up. Electronic timers are best suited for irrigation and drip watering systems. The ball valve timer is a good 'set and forget' system, ideal for morning and evening watering times and for when you're away on holiday, with a battery life of around 5 months. Solenoid timers are the best bet for professionals, with a higher quality valve and extended battery life, the solenoic water timer delivers time and again.
