Parts needed: -Ball Valve (look for a similar/exact part)
-Copper Pipe cutters
-Copper coupler w/o stop
-Sand paper/ mesh
-Flux
-Solder
-Torch
-2 channel locks
-wet rag
You will need to cut the pipe under the ball valve (leaving enough room to fit the copper coupler) and remove it.
If you are careful the pipe and the male adapter may be reused.
If this is not possible then you will need a male adapter and some copper pipe as well.
After the ball valve is removed, you will need to use teflon tape and wrap (clockwise - turning with the threads) the male sections on either side of the ball valve.
Re-thread the ball valve onto the main assembly and then re-thread the male adapter into the ball valve.

~Gardening Tip~
Now is the time to begin performing dormant pruning and rejuvenation pruning of shrubs. Taking dead wood or old wood out of bushes, such as a Red Dogwood - Cornus sericea, will promote new colored wood or better growth.
