I purchased this water heater in May 2004. It began leaking in September 2009. I was hoping for at least 10 years of usage with this unit. I'm disappointed and will look for a replacement that will not be a Kenmore. Appears they simply don't make them like they used to.
Update October 2009: I will now eat crow. I did end up replacing my bad water heater with the same Kenmore model (55 gal Power Miser 12).
As my previous post shows I was quite disappointed with the short life of my previous water heater. So, I did look around for other water heaters, I even looked at the new tankless models. I also went into the Sears store and talked with the sales rep. I opted to have a Sears tech come out and inspect the leaking water heater. The service tech was knowledgeable and courteous, a complete professional. The tank had simply failed and full replacement was covered under the warranty. I picked up the replacement from my local Sears and had it installed. It has been in place now for a few weeks. No issues. I do hope that this one last a longer than the prior one and hope that that one was just a dud.
