This would cover the cost of repairs (up to $4,000 per incident) to the water line which is on my property up to the street side valve on my water meter, which is inside my house. Pipe that's on the street side of the parkway is on City property and isn't covered by the insurance, but would be repaired by the water company. I know this because last year there was a problem with my Buffalo box that was repaired without cost by the water company.
Insurance includes replacement of pipe, filling in any excavation, restoring surface to original condition, and replacing sidewalk if it's necessary to remove or damage sidewalk.
It covers "normal wear and tear and leakage" but just about nothing else. Doesn't cover damage by me or by third parties or from natural causes like earthquakes, tornados, and floods, or any damage to added piping such as to an underground sprinkler system.
I've only been a homeowner for about 6 years, but it doesn't seem to me that water pipe damage like that covered by this insurance is very common. The houses surrounding mine were all built about the same time and, at least for the time we've lived here, I've never known anyone to suffer water pipe damage covered by this insurance.
My inclination is to pass but I'd like to hear opinions from more experienced home owners. Any comment will be appreciated.
