The whole function of winterizing your sprinkler gadget is to make certain that your pipes don't freeze and burst. When water freezes it expands, that is compounded when your pipes are pressurized.

Most incessantly frozen pipes are pipes that are above ground comparable to backflow prevention, sprinkler heads which are on risers, or pipes that run across the ground.

You won't ever get all of the water out of your sprinkler system on the other hand, it is important to get sufficient of it out so when it does freeze the water has a spot to extend to.

This will also be done the use of an air compressor, or it may be completed, by way of simply draining the water. Each will depend on slope and elevation, climate, and temperature.

Things You Will Need To Know
