    What do you guys prefer as the main turn on valve? most of our systems have gate valves...some have ball valves...from my experience, the ball valves are much easier to use and seem to fail less often, unless the lever breaks off...last year we had either a 1.5" or 2" system gate valve lock up and we had to replace it, digging down 4 feet and 4 feet wide, it was a huge pain in the ass...i figured i would ask you guys, i just don't understand why the gate valve is much more popular...

    Prefer ball valve. I see less failure. I've replaced many gate valves that fail and allow water to the system during the winter after we have drained down the system.

    If I had a valve 4 feet down, it would be something like a curb stop, and not a gate valve.

    I once went through a supply houses' entire inventory of 1.5" gave valves and every one had faults in the casting that would have let water leak by. A valve isn't much use if it lets water leak by, is it?

    I think gate valves are more popular, because they're cheaper.
    Ball valves are better in every regard, except in the one situation where you might want to intentionally restrict the flow through it, and have control over how much restriction you want.

    Gate valves do prevent the customer, or a newbie employee, from slamming on the water. A gate valve does slow down the process a little.

    I have seen a few systems that had a special "resilient wedge" gate valve shutoff. Nibco made them in small sizes.

    For something accessible I prefer brass ball valves. Now if it was 4' deep I'd go with a resilient seat gate valve, as Boots mentioned.
    Curb stop would work too, although I've dealt with a few that have become stuck and had to be replaced (by the water department).

    Bingo, and that was my criteria, also. I never used plastic.
