Benefits of Hiring a Lawn Sprinkler Repair Pro to Blow Out Your Sprinklers

Hiring a sprinkler repair pro ensures the job is done correctly, which prevents damage that leads to bigger repairs. Pros handle the task quickly and routinely, saving you time and stress. Because the work is exterior-only, you can schedule without adjusting your day. Most importantly, a pro uses the right compressor settings to protect PVC or polyethylene pipes throughout the system.

Here are the benefits of hiring a professional to blow out your sprinklers:

• Sets safe PSI for pipe type to avoid cracking and burst lines

• Uses 30 to 50 CFM air volume for controlled, effective blowout

• Brings the correct blow-out adapter and professional-grade equipment

• Opens and clears each zone methodically to remove all remaining water

• Closes and moves zone-by-zone until no water discharges from heads

• Stops water supply and drains at the hose bib before starting work

• Works entirely outdoors, so you don't need to be present

• Completes winterization efficiently from extensive, repeat seasonal experience

• Prevents freeze damage that can lead to leaks and costly repairs

• Schedules service before freezing weather to protect your irrigation system

If you’re unsure about the process or want to guarantee your system is properly protected, you might want to consider a sprinkler winterization pro near you to ensure the job is done safely and correctly.

Can I Hire a Handyperson to Blow Out Sprinklers?

A handyperson with yard and lawn maintenance experience can take on this annual blowout. Ask about their specific sprinkler experience and whether they follow the correct PSI and CFM limits. If they are not qualified, they may recommend another handyperson or a sprinkler repair company. As freezing weather approaches, availability tightens, so plan ahead. Balance convenience with the need for proper compressor settings to prevent pipe damage.
