How does that built in drain work or what does it look like? I'm having the city shut the curb when I'm there.
I vacuumed mains when I'm swapping a main valve but it only sucks out a couple of inches with the vac directly on the pipe.
Good Idea, I'll have her sign I can't really do anything from the house to the curb.
There is a hole in the side of the ball valve body and a hole in the ball. The hole in the ball is covered by the teflon seal when it's open and of course the hole in the body is only open to the solid sides of the ball with a seal on either end when the valve is open. When the valve is closed the side of the ball with the hole is towards the house and the hole in the valve body is now open to the cross drilled portion of the ball.
It's a little hard to describe but I tried.
It's different than a standard stop and waste valve. A stop and waste valve has no extra hole in the ball.
