Probably a wasted exercise. You want it to drain below ground. Here in the US we have frost proof hydrants that cut the water off below ground (usually in a bed of gravel) and drains it out. This way you don’t have to remember to drain the line.

Google frost proof hydrant for products.

If the ground freezes, the valve stopping water needs to be below the frost line. Any water that is above the frost line in a dead end is at risk of freezing and bursting.

Dig out the old line and put in a frost proof yard hydrant. They make them in varying depths to make sure you are below the frost line.
