Holman Digital Tap Timer is designed to make your watering schedule effortless. The most important component of an irrigation system is the irrigation controller. Holman Digital Tap Timer has a low energy, eco-friendly battery that operates the monitoring and display system.

The Digital Tap Timer connects to a standard garden tap and has a watering duration from 1 minute up to 12 hours and 59 minutes in 1-minute intervals. The Digital Tap Timer includes a 7-day watering calendar with individual day selection and can be scheduled to start watering up to 4 times per day.

An irrigation system plays an important role in the success of growing your garden, without a system in place you could potentially loose plants, or jeopardise their health.

Do they operate on a solenoid valve or a Ball Valve?

  • They operate on a solenoid valve, however we do a timer that is branded under the Aqua Systems label and available in Bunnings that is operated by a ball valve, the code is CO1905AS.

What is the minimum operating pressure, will it run off a tank?

  • Operating Pressure is 0.6 – 9.8 bar, and it will not be suitable for gravity fed tanks, however we do a timer that is available in Bunnings operated by a ball valve and is suitable for gravity fed tanks, the code is CO1603.

My tap timer makes a funny noise and does not open.

    If that is the case please try the following recommended solutions:

  • If you are running a low-pressure drip system, you need to install an Air Release Valve (102646) at the highest point of your system and above your drippers.
    This breaks this the air in the drip line and allows to suck in air through the air release valve and prevents the drippers from blocking due to dirt.
    This also allows for the diaphragm to work properly.
