The Mist Auto Drain Valve is an essential component for any outdoor mist cooling system. It is designed for installation in one of two ways: either thread it into a 10/24 female-threaded nozzle opening or insert it into any professional Slip-Lock fitting

  • Prevents premature mist nozzle clgging and prolongs the life of your misting system
  • Versatile installation: install in any fitting with a 10/24 female-threaded opening or at the end of any orbit slip-lok
  • High-quality brass construction
  • Easy to install

Rated 1.0 out of 5.0 by This product kills the water pressure to the nozzle This piece absolutely kills the water pressure to your misting nozzle. I bought a pump that boosts pressure to 180 psi and you could barely tell it was on. Normal water pressure from your hose bib should allow mist to come out of the nozzles. I hooked 1 nozzle up to my hose bib with this piece attached and no mist would come out. I took this device off and screwed in the mist head only, and mist poured out. I hooked up my entire system with 12 nozzles without these and mist came out all 12. I then turned on the pump and it fogged the area like it was suppose to. I was almost ready to spend $650 on a 1000 psi pump. I would not recommend this part for any system. June 15, 2013
Rated 1.0 out of 5.0 by Product doesn't work Doesn't work. Shoots a steady stream of water no matter how you set it. July 1, 2014
Rated 1.0 out of 5.0 by Avoid these I have purchased two of these thinking the first one was defective. Once they turned on they did not turn off. I will replace it with another mister. May 26, 2014
Rated 1.0 out of 5.0 by Never understood it`s purpose. I bought another poorly built Orbit product, an outdoor misting system. The drain part seemed like a good idea but I had no idea how it was supposed to work. It did nothing. The misting heads worked for awhile but began to plug up. System leaks a lot which isn`t good for it`s location. It would be real nice if you could easily clean out plugged heads but I haven`t found a solution. I`m still looking for a better made misting system to buy. My pets depend on it! June 28, 2013
