Gilmour Single Outlet Mechanical Water Timer for Garden Hose - Automatic Irrigation Timer for Sprinklers, Drip Systems & Outdoor Plants | Perfect for Lawn Care, Garden Watering & Efficient Irrigation

I'm changing my review of this product. After having three of these timers fail, I purchased another timer and that one failed too. I started to realize that it might not have been Gilmore Timer after the third one didn't work but I wanted to test another's manufacturer's timer to be sure. I dug out my water pressure and stuck it on my irrigation line. The pressure was sky high. The water was forcing its way past the valve in the off position.I can't blame Gilmore for a lack of troubleshooting instructions. I bought this product because it has always been simple to use and has been rock solid in how it works. Attach one end to your faucet, the other end to your water hose and turn the time on. It just works, and it works great.I fixed the problem by putting a pressure reducer on this section of pipe. Now my Gilmore Mechanical Water Timer works. I will go back to using these timers. I have six and have three more faucets to put them on.Previous review ...This product's quality has gone seriously downhill... I had ordered six and they worked perfectly. The last two I ordered both had the same problem. Water would flow when turned off and it would stop when turned to a time and ticking. Amazon was great and replaced the 1st one with this problem, but then the replacement had exactly the same problem. Now returning both for a refund and will order one from a different manufacturer.
