text: If AHS assigns this plumber I suggest you call the number and request a different contractor When scheduling I asked if the RO repair is a covered plumbing item and they would not comment but said that if it was not covered they could still perform the work The guy came out looked at it and said not covered and will cost to replace I had another plumbing issue that he would not even look atjust wanted his service call for no service whatsoever and left Later I found that my RO system can be repaired tank replaced for Lousy service from this company from the first phone call
