Product Description
Amazon.com Review
Does it seem like you spend more time maintaining and operating your sprinkler system than you spend on your lawn itself? Now you can avoid getting bogged down with daily details and sprinkler scheduling thanks to the Gardena water computer. This handy device attaches directly to your outdoor spigot and gives you complete control of your sprinklers, pop-up sprinklers, and drip-head irrigation systems. Programming the water computer is relatively easy. You simply enter the start time, watering duration, and watering days or cycles; the computer does the rest. Up to six different programs for six separate watering lines can be entered at once to provide watering periods of up to nine hours and 59 minutes. In addition, the program unit can be removed from the computer with the click of a latch, allowing you to do the programming from the comfort of your home before reattaching it to the base. A hose connector is also included for easy coupling without a lot of tedious twisting. The unit uses one 9-volt alkaline battery (not included). It can also be used in conjunction with the Gardena electronic rain sensor or soil moisture sensor.

This really works!,
By A Customer
This review is from: Gardena 31815-4 Water Computer (Lawn & Patio)
Found this idea on a local cable TV do-it-yourself show. Tracked down the Company in Germany and they put it on Amazon.Com for me to order. Put timer together with Auto distributor unit 31198-4 and it allow you to hook 6 hoses with each having its own watering schedule. Tried it and it proved that everything they said it would do - it did and better than expected. Great product and great customer service.

Good once you figure out how to program it,

This review is from: Gardena 31815-4 Water Computer (Lawn & Patio)
This is a very effective timer, once you figure out how to program it. The directions jump around between program functions and manually operating it. It took me a hour or two to get my programs organized, but now I don't even have to think about it. I attached the Gardena water distributor and can water several different areas of the course of the day. Very helpful for someone who travels alot.

Good idea -- weak technology,
By A Customer
This review is from: Gardena 31815-4 Water Computer (Lawn & Patio)
We have a large heavily shaded yard that requires considerable watering over the summer. We have three of these computers running with multiple water lines feeding out from each. This is a terffic idea if you have a lot of regular watering to do -- and, it really saves you loads of time. Unfortunately, for two of the past three years we've had to replace at least two computers. In fact, we're ordering two water computers today. I just wish they built them to stand up for more than a year or two.
