Only one cycle works
I bought a couple of months ago. One start time works on each cycle only. The second cycle, the valve doesn’t open but the screen shows it is watering. What am I doing wrong??
Purchased in January 2020.
Unreliable & Expensive
As professional landscapers we know that irrigation systems can sometimes be troublesome, but with the right gear any teething problems are quickly solved and you'll end up with a trouble free system.
I've had this particular unit operating without any issues for the last 18 months so they're not all bad but unfortunately the Holman tap timers have proven to be unreliable, having seemingly a mind of their own as to if, or when, or through what outlet they will do their intended job, regardless whether it has 1, 2 or 4 outlets.
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?
My holmans whiz 200 is leaking between the hose fitting and the body of the unit
How can I sort it out
Hi Adrian. Myriad possibilities and probably many you will have tried - but if it helps anyone? No knowledge of Water wiz 2, but looking at all my timers there would appear to common points. Let's start at the beginning. Disconnect any hoses and fittings attached to WWz. Turn off tap to unit and ensure unit is not set to supply water. Turn on tap. Is any water apparent. I have had a few issues with fitting to tap leaking, water dribbling down back and appearing at the bottom as a leak. If leaking from tap fitting, 'Nip' up tighness and check again. Check washer in connector and replace. Fixed?? OK no leak from connection. Is water still appearing at bottom - consider a hair-line fracture from either over -tightening connectors OR was unit exposed to frost. Get a new one and remove before your expected first frosts! No leaks, then check hose connectors on outlets. The rubber washers harden over time and either need a further 'nip' up from finger tightening, or replace the washers. Ensure hose is properly connected to hose connector and hose connector firmly 'snaps on ' to unit nipple connector.
Hope this has helped. Cheers.
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.
