Do I need a ball valve with a drain?
The only use these valves have are when you must drain a line to prevent freezing, and then only if the valve is at the lowest point in the line. Save yourself grief and use regular valves.
Is there a correct way to install a ball valve?
VALVE ORIENTATION: The valve stem orientation is not critical, however any deviation from vertical is a compromise. Installation upside down is not recommended because it can cause dirt to accumulate by the stem packing. The best practice is to install with the valve stem facing upwards whenever possible.
What is a waste drain on a valve?
It’s quite simple really. When you turn the water off in the Fall, this “stops” the flow of water past the valve. When it is in the off position, a hole is opened up at the bottom of the valve which allows water between the stop and waste and the regular sprinkler valves to drain out; thus, “wasting” the water out.
How does ball valve with drain work?
A ball valve is a shut off valve that controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotating the ball a quarter turn (90 degrees) around its axis, the medium can flow through or is blocked.
Are plumbing ball valves directional?
1) Ball valves are designed to be opened by rotating the lever handle in a counterclockwise direction, and closing in a clockwise direction. The handle indicates the ball port direction. 2) Under certain conditions, throttling flow in the near-closed position can destroy the valve seats.
Is a stop and waste valve necessary?
If you need a stop and waste replacement, the valve’s main purpose is to prevent pipes from freezing during the winter. The valve allows the water to be drained effectively, preventing any issues with pipes that might burst with ice.
Are water ball valves directional?
I’ve never seen a ball valve that is directional. If you look inside, you’ll see the guts of it are symmetrical. I would say the general rules of thumb for this are: If you can even change the handle direction, be sure that off is perpendicular to the pipe.
