What We Do:
We use high volume, low pressure air compressors to blow out sprinkler systems. High volume is necessary to do a complete job of removing all of the water from the system and low pressure is necessary in order to not cause damage to the sprinkler heads, valves, pipe or pipe fittings. We own our compressors which gives us the versatility to winterize either early or late in the season while other companies rent their compressors and are not available.
✓ Blow out connection on discharge side of main shut off valve
✓ Apply air pressure from the compressor to the system
✓ Open zones from controller or automatic control valves
