Fails Quickly
Like other reviewers, these failed almost immediately. the water blew a hole right through it..

    valves fail!!!
    i have replaced 17 of orbit's brass valves that failed with these black ones and it's only been 2-1/2 weeks and the black ones are failing. there is a little square silcone stopper for the check valve and the water blew it through the hole that's suppose to stop it. i give orbit a big F!!! for not producing a automatic drain valve that will work. i would give zero star's if i could.

      Purchased a 10 pack. At least 3 are leaking . They do not close when pressurized. Anything with poor quality is a poor value.

        No. Home Depot doesn't carry the parts needed to complete the connection. I cannot find them elsewhere so the drains can't be connected.

        I can confirm that these Orbit drain valves will last more than 2 years (refer to my previous review by JohnnyFYX from 2015). I am writing this updated review because I am purchasing more of these drain valves for the zones in my front yard. I install a valve just before each of the sprinkler heads inside of a small round sprinkler access box so that i can inspect or replace the valves as needed. It has been just over 2 years since I installed 3 sprinkler heads and 3 drain valves on my back yard sprinkler system. and everything still works great! Keep in mind that I am in south Texas where the winter season gets below freezing for maybe 2 weeks out of the year. I am sure this is a factor in the longevity of my drain valves... I cannot say if you will get the same results in a colder climate. I would recommend a more durable brass drain valve if you expect extreme cold to hot temperature swings year after year. The only reason I give this drain valve 4 out of 5 stars is because I have no expectation for this part to last as long or longer than the sprinkler head or any other part of the sprinkler system. For how it performs, it's tested lifespan and its price, I would still consider it acceptable and worth the purchase. Just make sure to purge your water lines of all debris before you install these valves or any sprinkler head. Otherwise, you will risk clogging/damaging the drain valve and/or your sprinkler heads. Also, make sure that you use a sprinkler box to house the drain valve for occasional inspection and easy access to replace as necessary. I recommend digging a post hole to a depth of at least 6 to 12 inches below where the drain valve is installed. This allows for drainage water to collect and helps prevent mud/soil from clogging the drain valve. Over time, this hole will collect mud/soil and may need to be cleaned out. I would suggest replacing the drain valve if it ever gets submerged with mud/soil.

          DO NOT USE!!! This product has a 100% failure rate within two years of installation. It will gush water during zone run time as if nothing was there. Do not cheap out by using this part.

            Works as designed
            I purchased 2 different versions of these Auto Drain Valves (Orbit green 1/2" version and the Orbit black 1/2" version). Both function exactly the same, but the green version seems to have a more durable design due to its thicker plastic hex-head. The black version as pictured online has a much thinner head with ridges on the rim to improve hand grip when installing/removing this part... This implies that the part should only be installed hand tight (for good reason, as it could easily crack apart if you tighten it with too much torque). The green version has a hex-head that allows you to use a wrench to get a tighter than hand-tight install; however, it is also possible to crack the plastic head if you tighten it with too much torque. I would recommend first hand tightening the green version of the Auto Drain Valve, and then using a wrench to tighten it and extra 1/4 turn to prevent leaks from the threads. Tightening it anymore will risk damage to the part when installing it or in the future if you ever have to replace it. I gave this item a Good overall rating because I know there are higher quality brass versions of this item that should outlast these plastic versions. For a plastic auto drain valve, the price seems to be higher than it should be compared to the brass versions. I noticed that some reviews on here and other websites claim these parts are garbage (need a bit more info explaining why it’s garbage or what the issue is) or that they are defective and constantly leak. At first I did believe that 2 of the 3 valves I installed leaked because they were flowing water about as fast as a faucet when I turned the water on. Then I realized that because I was purging the newly installed PVC lines of any dirt and contaminants, I had not built up enough line pressure to close the Auto Drain Valves. It just so happened that 2 valves that leaked were also on the lowest point of the entire system. After temporarily removing the valves and capping the lines to finish the purging process, I reinstalled the valves and then installed all of the sprinkler heads. Now, the irrigation system should build enough pressure to close the Auto Drain Valves and officially test the valves for leaks. After the lines purged the air out, and the sprayers started popping up and functioning normally, each of the Auto Drain Valves stopped leaking like faucet and was minimally dripping which is acceptable if you’re only running the system for and hour or so once or twice a week. When I turned the water off, the sprinkler heads dropped and the Auto Drain Valves started to purge water from the lines as designed. I tested this process a few times to be sure the valves weren’t leaking when the system was properly pressurized (only with the sprinkler heads installed).
