After an unsatisfactory experience with another company, I called isley's. They were able to answer my general questions on the phone and schedule a same-day service call. George did some trouble-shooting and was able to rectify thed problem with the RO system. He then did a diagnostic check of the water softener components and gave me some suggestions on how to can clean the brine tank.
I am quite impressed with isely's based on this initial service call.
