We live 350km away from store... took it home... programmed it and only 1 water station worked properly. First station would sometimes allow manual override and other times it would not open the valve. Station 2 worked how the product should have but then station 3 and 4 did not open the valve at all. I am worried about getting a replacement and having to drive 700km round trip to be disappointed again.

Flawless so far
Has worked flawlessly for the last 18 months and will hopefully continue to do so for a while to come. I very rarely review anything but the one star this thing is averaging is not justified in my opinion. Fingers crossed I haven't cursed it by writing this review.

Lasted 12 months
Disappointed to read these reviews as mine has now done the same.
The system has been resetting its time, so unless i check it the system wont come on when required. Middle of summer? Not ideal. Then when i use manual on, put a time in, it starts, i can not use manual off i just have to wait it out... but not the time i input, whatever time it feels like. Sometimes a half hour, sometimes ten minutes. I have tried new batteries even though it made no indication of being low. Still no joy. Sometimes no water comes through (at least once a week)... has anything been changed since the below reviews? Very unsure if i should replace it with the same if i will just get the same model.

No Water Flowing Through When Programmed & LED Display Script Lights Up & Timer Resets
Firstly, when these units work, they work brilliantly. But..there is a BUT though. Initially thought it was something I was doing as when I first installed the 400, it intermittently did not allow water to pass through the Water Whiz 400 it when programmed but it has now become more regular. The display shows the tap with water flowing symbol in the top of the screen, the timer clicks to open but no water flows through the designated outlet or any of the other 3 outlets. I also noticed that all the LED screen script light up & the time of day r...esets itself. I also have a Water Whiz 200 that has started to have the same problems in the past month. I will be looking at taking both units back to Bunnings for a replacement of both units. If they fail after replacement I will be getting a refund. These units are not cheap items with the 400 at $149 & the $200 at $99 so should last years at least but look only to have lasted 10 months. I have both units in weatherproof enclosures to protect them from the weather so weather damage is not an issue. I will be looking at other units if these fail again. December 23rd 2019 Update: Holman pls explain why solenoids continue to stick shut I have a Water Whiz 200 & 400. Let me say, these units work brilliantly..... when they work. I have just replace the failed 400 unit b/c the solenoids on outlets 2 & 4 would not open even though the solenoid made a click sound. This is an inherent problem with these units as indicated from the reviews. What is Holman doing to rectify this issue as I will be returning my units if they fail again & get a different suppliers unit or a refund. December 24th 2019 Update: Warranty replacement unit failed after 10 hours being reinstalled UPDATE: Installed the new warranty replacement Water Whiz 400. Tested it with no problem, all solenoids worked manually. Programmed it & waited for the scheduled watering to occur. NOTHING .... and the unit is only 10 hours installed. Checked the unit operation & NONE of the solenoids would operate even though they clicked signalling they were trying to open & the water flowing symbol was displayed on the screen. Reset the unit but still none of the solenoids would open. Checked the delay setting but it was 0. Reduced the pressure on the intake but still no operation. Holman, what is the issue with these units? Why are the solenoids not operating reliably? This is the fundamental system for operation. There is no way you can set & leave secure in the knowledge that they will operate as required. This replacement unit will be going back for a refund & I will be looking at other options.

Nice interface and flexibility. Would be perfect if it allowed water to pass through itself.
Loved the user interface and flexibility of programming. Four watering zones each with 4 individual programmable runtimes including frequency (select which days to water or the option to choose every second or third day) gives heaps of flexibility.
Unfortunately after a week it simply stopped working reliably. Had it replaced and that unit failed within a couple of days.
Buy Orbit ... you won't be sorry!
I bought the Holman Waterwhiz 400 4 zone watering kit and it's absolutely useless! I returned the first one to Bunnings only to find second had exactly same problems! Despite having pressure valves on each zone the unit is totally unreliable, my new Sir Walter Buffalo lawn had gone brown twice due to sprinklers not turning on as programmed. I've resorted to resort to using my old Pope Rainwave sprinkler to bring it back to life. Yes I contacted Holman but they're full of excuses wanting to blame me when I paid thousands to have professiona...l, award winning landscaper to do my garden ... Not happy Holman. Conversely my son's had the #Orbit 4 zone system working his garden (one in front, one in back) for the last 7 years without any issue whatever. As Bunnings don't stock it anymore I'm now going to return the Holman and order myself #Orbit system online. Steer clear Holman products is my advice. I'll NEVER purchase another holman product ... ever!!!
Questions & Answers
This is my second Holman Water Whiz 400 and I am having the same problem. This one has served well for nearly 2 years. I have three outlets connected. Of late the Holman is leaking once again from the neck of the unit. The flat top of the white neck has broken off from the body of the main neck. Can this part be replaced? Or do I now need to buy a new one again?
I Have a Waterwhiz 400 and the zone #1 will not close. I have tried the reset function, the manual running of zone #1 for 1 min etc, but it still will not close zone #1. When I run the manual function on zone #1 it almost instantly shows reset on a blank screen.
Your earliest attention will be appreciated.
Hello Byron, for product support, please contact us on 1300 716 188. Thank you, your Holman Team!
My Water Whiz 400 keeps resetting the time by itself. I have it on Auto, when I come back to it is on 'set time' and the time has changed.
How can I stop it doing this please?
Hi Nick, I have never experienced this issue myself. Have you tried to reset the Water Whiz and try setting the time again. To reset it, press and hold the OK button till the time is reset to 7.00am. The unit will be in default settings now. Also make sure that your batteries have a good charge and are not close to being dead.
Dear Dr DG
Thank you for your prompt response
I renewed batteries (they seemed OK) and reset as you suggested. Clock seems to work now - and switches on at the right times etc.
It runs the first channel, then gets stuck on the second - won't send any water now even on manual to channels 2,3 or 4. Channel 1 works fine.
Any ideas? Maybe a malfunction?
