IT’s ME…
I have had the Water Softener company (Kinetico) come out first and they said that it would not be their tanks. However, they do have some new and improved tanks that they are bringing back tomorrow free of charge. So, it must be the Water Heater. It is definitely plastic particles that keep appearing in, yes, multiple faucet screens. The heater is a Ruud that is about 8 years old. We think we will just replace the unit instead of repairs which always seem to cause problems. Not sure yet if it is the dip tube or anode rod – and assuming it is the water heater with the info the Kinetico Water Conditioner service persons input.
