When you replace a part is the previous part inspected for signs of reasons it failed?
You may have a supply line or valve that is the source of the problem. It might be your water is hard as others have suggested. My previous home had iron pipe. There were constant problems with the plumbing. Currently my home uses plastic pipe. Even with a high iron content in the well water there have only been two plumbing problems in the past ten years if you don't count the water heater having an element go bad.
Are you on a well or a municipal water supply?
