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.

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.

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

Holman again

OAnother Holman product that fails went to use it again this year and it has seized up surely you should get more than one or two years from a $40 product

Hi Andrew, we're sorry that your Tap Timer has failed! We recommend storing tap timers away during Winter to avoid prolonged exposure to cold weather, especially if your area is prone to frost. Thank you.

Battery brand

Holman specify an alkaline battery for this timer. However only Duracell alkaline batteries work.

Why is this?

Cheap - not lasting

Worked ok for 2 months. Rusted out. Would not recommend.

Great device

I have used this in my garden for years. Great inexpensive timer.

Absolute 💩

If I could give this zero stars I would.

Complete waste of money. Worked once then started leaking and moisture got into it and stopped working.

Heed all of the reviews and spend your money elsewhere.

Shame on you Holman for not sorting this issue.

Hi Habibi, we're sorry you've been having trouble with the 2 Dial Tap Timer. We've passed your comments on to our Product Development team to find a solution and address these concerns. Thank you.

Worthless

Didn’t even work for first time. Useless product.

This sounds like it is a faulty product, if you can please get in touch with our customer service team support@holmanindustries.com.au so they can assist you with further troubleshooting.

Constantly leaks

Tried several different thread options along with thread tape and this still doesn't provide a secure connection. Should have heeded the reviews on Bunnings website.

Disappointed

These things don’t last outside, they work when new but soon stop turning on, they work in manual mode but not automatic. I suspect that they draw in moisture and that causes problems with the electronics.

Works Well

Purchased this timer to replace another brand that was much more expensive. Been using this for sum time now with absolutely no issues at all. Very easy to set up.
