My tap timer makes a funny noise and does not open

  • 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.

I have done a lot of cash jobs for irrigation setups for customers and have used around 8 of these and haven't had an issue as yet with any. Very easy to setup and are really easy to show the customer how they work and run.

Absolute rubbish, don't bother buying

Avoid this product, works for the first cycle and then won't turn off on 2nd cycle. There are loads of reviews online saying the same thing, and also that Holeman have acknowledged the issue and done nothing about it. Don't waste your time, money and water on this terrible product

Works well then doesn't.

Simple and easy to use, although the battery change is fiddly. Stopped working after 18months. Will not buy again.

battery wiring needs a design re-think

The battery wiring needs a design re-think. When I went to change batteries, I ended up pulling out (and therefore ruining) the wires that are attached to the battery. It is so fiddly and the wires are quite thin and if you pull on them with any sort of force, (which is easy to do in error) when changing the battery, its broken forever. This is my second Holman timer (the previous one stopped working, not sure why) so have to have a think if I persist with this type of product and Holman products in future. When it worked it was fantastic.

A consumable item

Works really well until it doesn’t. I got 2 years out of it before it jammed up, the mechanism all of a sudden only opens enough to allow a slow drip through and there is no way to get inside for any repair or maintenance attempt. Not worth trying to get a warranty on either.


Don't bother.
In the past 18 months, I've gone through four of these. All of them either stopped turning on, stopped turning off or both. I've even returned one to Bunnings in that time and got a replacement. The last one broke today - it couldn't handle standard water pressure and broke, flooding the garden in the process. I realise you get what you pay for, but if I can't leave it unattended, it's useless.

This simple tap timer saved my bacon, or more accurately my tomatoes, capsicum, eggplant, herbs, and other decorative plants during the last end of year holiday period. I'm usually away over this period and it's a gamble as to what survives. This time, with the help of nightly waterings managed by the timer, I came home to a green and flourishing garden!

It's best if you set up a schedule and the let it go. If you try to change things around, then it can get a bit confusing and you need to be around to make sure a new program has been set properly.
