FAQ

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.

Can I run this off a gravity-fed or low-pressure system?

This timer is not suitable for low pressure applications. It is designed for normal tap pressure 250kPa to 600kPa.

If I use my timer manually, will I need to re set my timer?

No. If you press the ON/MANUAL button, your timer will run for the duration set then turn off. This will not affect the program.

My timer shows it is watering but there is no water coming thru?

There may be an airlock in the system. Disconnect the timer and reset it. Flush your irrigation system before attaching to the timer again.

My timer will not turn off after the programmed run time?

Setting multiple start times or incorrect programming may have been entered.
When going thru the programming of your timer, you first set your current time and day.
Next is the run time, e.g. 20mins
Next is the days you wish to water, e.g. all 7 days.
Next is the start time, you can make the program you have already set, (every day, for 20 mins) come on up to 4 times per day, hence to 4 available start times.
Entering 7am in start 1 and 7pm in start 2 (with start 3 & 4 set to OFF) now means you have your water come on every day at 7am and again at 7pm and run for 20mins
You cannot enter a start time for each day individually.

Is my timer suitable for short-run drip or micro spray irrigation?

Yes, although a pressure reducer placed on the tap, before the timer is recommended. If only running a few drippers or sprayers, it is not suitable. Use the CO1603.

How do I reset my timer?

Simply remove the battery for 5-10 mins then reinsert. Your timer will be reset to default.

Is it OK to use my timer over winter?

We do not recommend the use of your timer over the winter period. It will not handle low temperatures, below 3 degrees Celsius may damage the timer. We advise the timer to be removed over the winter period, or allowed to drain if left on the tap.

Can I get spare parts for my timer?

Yes, some parts are available for this timer. For more information, please contact us.

Preparing tap timers for winter

Be sure you check with your local water authorities for any sprinkler bans
We recommend either reducing the watering time or turning it off completely
In really cold climates, we suggest that you remove the battery and make sure there is no water left inside the tap timer
If you live in an area that gets frost, we recommend taking off the tap timer completely and storing it away for the meantime

Reviews

Auto digital tap timer

I now have four of these timers on my watering system. I find them easy to set up and use. They are accurate and run according to any appropriate program set. Highly recommend.

Hi Eion, thank you for taking the time to leave this review. We're glad you're happy with your tap timers! Have a great week, The Holman Team 😊

Works well, but impossible to read display in bright conditions

Working well and reasonably clear and intuitive programming. However I have the unit on an NNW facing balcony, and the display is impossible to read in direct sunlight or even bright indirect light. The photo is late afternoon on an overcast day - about the only conditions in which the display can be read. Shame, as it is otherwise a useful unit.

Holman water timer

Purchased timer three month ago Bunnings Frankston in the beginning timer worked as programmed three months later timer doesn’t turn off and flooded my garden

Automatic Digital Tap Timer

Found this product very easy to setup and it works really well. Have been very happy with the product. Certainly very much easier to use than a previous tap timer that I purchased.

Manual ON is a favourite feature.

I had 3 manual 2 button timers. One stopped working and was replaced with a digital timer on 05/08/2024. I like the precise clock settings for 4 routines. I also really like the manual ON for an extra run when I can easily divert to another area via an an online manual valve. The other 2 manual timers won’t dare play up because they know what will happen. Automatic watering while we are away is so good.

should be off the market

I bought about 15 of these from Bunnings, plus those rectagular batteries, never keep receipts. All of them failed within 6 months. Very disappointed.

Timier makes life Easier.

The clear instructions and the simple process to set the closck and program the timer is remarkable and is a great product to have in my garden. Thank you Holman.

Only lasted a year

Worked well but then digital display froze. Just installed new battery. Removed battery waited 2 minutes and then tried again, still frozen. Keep your receipt people.

Hi Meagan, thank you for your feedback, if you could please contact our Customer Service Team at support@holmanindustries.com.au for further troubleshooting, we may be able to resolve this issue. Thank you, Holman Team.

Automatic Digital Tap Time

This item is easy to set up, especially with the video format instructions. Well - priced and works appropriately. Happy to recommend it for DIY irrigation projects.

Auto tap timer

I have blown the top of 10 of these in the last few years.
The plastic flange near the tap blows off.
I have installed a pressure reducer at theMain.
I have reduced the water flow at the tap and it still blows.
Thanks Bunnings for your return policy
