Orbit WaterMaster 4 Zone Sprinker Timer 

The first video I found and it’s a real winner. Super easy to follow and I can do it! Thanks for your help!and I would add a small critique to help you make even better

Thank you for this video.

This timer has worked great for about 4 months but now will not shut off the zones after running for the programmed amount of time. I have replaced the batteries and also took the case apart but there is no way to open the mechanism to clean it. The system looks very clean though.

Very helpful! Do you have a video showing how to activate or replace the battery? Thank you!

I have this clock for 6 zones. Is there anyway to program this clock to split days for 3 zones at a time

The hinges in my 57975 cover have snapped. How can I buy a new cover?

How do you set the date and time on these old things?

Nowhere in their owners manual is there an illustration showing where the battery is located. Pathetic.
