I just had a new Powerline Water Softner and a Kinetico R5 RO system installed. Since that time (One week), I have found my ice maker taking longer to make ice, and the ice is hollow and smaller in size. I have also had a problem with the washing machine where I cannot get cold wash/rinse water to load the washer. If I change it over to warm, I get hot water to load the washer which tells me the cold water is not loading. The cold faucet in the washtub right beside the washer works just fine. It feeds right off the same line as the washer. My wife also have had a lot of sediment in the bath tub tonight which was sand-like and brown in color. Can anyone tell me what my installers should have done before leaving my house or have told me before they left?
