Orbit 57280 3/4" FPT L-Series Automatic Sprinkler Valve

Work way better than the older designs, they always seep and I replace with these. Do yourself a favor and install the manifold with unions and replaceable orings

Great product and excellent price

We live in the "high desert" of CA, annual rainfall is about 10", and that is mostly in the winter. I put together a 6 manifold system. The controller has a glitch, it won't let you program #5 and #6 unless you start with #1 and reset (or maintain) the settings and just go in order. I have them in a little shelter so they do not get any sun and are at an easy hight to work with. They all worked for the first six month growing season. Two did not survive the winter, although I thought I had drained all of system. I replaced them. NONE of them survived the second winter although after I turned the water supply off, I left the system on for a day to be sure it drained the valves. Two will not turn off, 4 will not turn on. I did all the things the on-line fixers recommended, even buying 2 new solinoids, which did not solve the problem. So, I am buying new ones, same model, since they will be easy to plumb in, I think this winter I will take them out of the system and put them where freezing is not an issue, and put a drop of oil on the solinoid. The cost is small compared to the value of vegetables we grow, let alone the flowers and shrubs. My experience with Chinese products is that quality control is missing, so sometimes you get a good one, sometimes you do not - 10 electronic things failed in my new Audi - all made in China - in the first 50,000 miles, none of the replacements have failed in the second 50,000 miles. 3 of the 6 have failed, and, and 3 are going into their next season. Well drained when turned off, no water in lines in or out.

Good...

I had a pretty bad leak on one of my valves due to a damaged diaphragm. I used this to replace the entire valve on the bad valve on my Orbit 57253 3 valve system. This was a very easy fix thanks to the easy detachable parts and I no longer have leaking sprinkler heads. My only complaint, not really related to this product is, a replacement diaphragm is 50-60% the cost of an entirely new valve.

Good quality valve that is still working great 2 years later

Orbit 1" Automatic Sprinkler Valve. I used to replace existing valve. The new valve is a fraction of an inch shorter than the old one but works fine.

Did not use with water but with air. Made a air cannon to shoot a bag over limbs to tie a rope to direct fall of trees.
