Also last fall we got a Mark8000 water softener that is pretty well eliminating any deposits anywhere in the system.
It is regenerated with a regular box of table salt. How often is a function of the water hardness level. In Bouse AZ it needs regenerating about every 10 days. Here in Palisade CO about once a month.
