This is a great stop & waste valve. In the 20+ years I have been doing water lines and sprinkler systems, I have never had one of these valves fail.<\/p>\n\n\n\n

Other valves that I have encountered don’t perform like this valve. They are either extremely hard to turn on and turn off, or they are designed in such a way that it is hard to keep the meter key in contact with the valve. I think the advantage of this valve has over the others may be the oriseal feature in the top of the valve. This feature makes this valve easy to turn on and off compared to other valves.<\/p>\n\n\n\n

Usually this valve is buried 3′ – 5′ deep, and access to the valve is through a stand pipe that is 2″ – 4″ in diameter. See my post on a typical stop & waste valve installation <\/a>to get an idea of how these valves are used. Notice from the image that the valve has a flow arrow on the valve showing the direction of water flow. And notice on the valve that it has a drain port on the side of the valve that will drain the water out of the sprinkler supply line when the valve is shut off.<\/p>\n\n\n\n

Remember when turning on or shutting off a stop & waste valve to make sure the valve is completely on or off. Otherwise the valve will leak out the drain port continuously. What I like to do is turn the valve until it “bumps” to make sure it is on or off. On this valve it requires a 1\/4 turn clockwise to shut the valve off, and a 1\/4 turn counter clockwise to turn the valve on.<\/p>\n\n\n\n

Lastly, if you are installing a stop & waste valve remember to wrap the valve with valve wrap (I use landscape fabric) so that small rocks don’t get into the drain port and keep you from operating the valve.<\/p>\n\n\n\n

Pros – Durability. Retains ease of turn on and shut off for years.<\/p>\n\n\n\n

Cons – None that I have encountered yet.<\/p>\n","protected":false},"excerpt":{"rendered":"
