Winterizing your Irrigation/Sprinkler System

Residents and businesses are asked to isolate their irrigation/sprinkler system from the rest of their water supply before winterizing to help ensure proper water quality for all residents connected to the City’s potable water supply and avoid system failures. 

Irrigation companies/landscapers will use an air compressor to winterize an irrigation system. The compressors are used to clear out residual water from sprinkler heads and pipes to avoid potential freezing. 

If you do not isolate your sprinkler system and shut the valve off from the rest of your water supply, air will go into the City’s water main, your home’s interior plumbing fixtures, and service line. The air can create discolored water or disrupt the flow from your faucet, causing it to ‘spit’ water. In some extreme instances, the air can cause damage to interior plumbing fixtures, a service line leak, or even a water main break.
