Irrigation and insurance

The practical takeaway is that winterization is partly an insurance decision. If a system freezes and splits because it was never blown out, an insurer can reasonably characterize that as a maintenance failure. Keeping a dated receipt for annual winterization is cheap protection for that argument.

Damage to the house is a different question from damage to the system. Water from a burst irrigation line that reaches a basement or undermines a foundation may fall under a different part of your policy than the pipe itself. Report promptly and describe what happened accurately.

Some insurers offer buried service line endorsements that cover exterior underground lines. Whether that includes irrigation, and on what terms, varies by insurer and state. Ask before you need it, and get the answer in writing.

If a contractor's recent work caused the failure, that's a liability question rather than a first-party claim. This is why you ask for a certificate of insurance from the insurer before work starts — an uninsured contractor's mistake becomes your loss.

How to choose

Keep winterization receipts

Dated proof of reasonable precautions is your defense against a freeze-exclusion argument.

Ask about buried service line coverage

Some insurers offer an endorsement. Ask whether irrigation lines are included and get it in writing.

Report water reaching the house promptly

Delay is the most common reason a water claim gets reduced. Report even if you're unsure it's covered.

Photograph before cleanup

Dated photos of the failure and the water path are the evidence the claim rests on.

Verify contractor insurance up front

If their work caused the damage, their liability policy is what pays. Get the certificate from the insurer, not the contractor.
