|Hi Larry, your link didn't work for me. My dip tube had no blockages whatsoever. I could easily blow air through it.
Today, I spent a lot of time with AO Smith trying to get warranty coverage for my water heater resolved. They finally gave me a parts voucher, i have to pay labor. I then spoke to an AO Smith authorized local plumber, who told me that he has seen similar failures before, due to our extremely hard water. He would not service my heater. He said that the tank is failing internally and that no parts, other than a complete replacement will solve my problem. Unfortunately, because I don't have a leak yet, I may be out of luck.
