Rated 1 out of 5 by from 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.

Rated 4 out of 5 by from It works, but don't remove I don't understand the other reviewers' complaints. My misters worked just fine. The only time I had problems with low pressure and water shooting out were after I removed the valve while the water was on. The instructions say not to do that. Now I have to replace the valve. But the product does work really well, otherwise.

Rated 3 out of 5 by from don't mess with the valve! My mister system worked up until I messed with the valve. Then I had to buy a new one. I guess it was a lesson learned that I needed to pay better attention to the instructions. Once I bought the replacement valve and installed it, the system worked great and I never messed with the valve again.

Rated 1 out of 5 by from Product doesn't work Doesn't work. Shoots a steady stream of water no matter how you set it.

Rated 1 out of 5 by from 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!
