If AHS assigns this plumber, I suggest you call the 800 number and request a different contractor. When scheduling I asked if the R/O repair is a covered plumbing item and they would not comment but said that if it wasn't covered they could still perform the work. The guy came out looked at it and said not covered and will cost $600 - 800 to replace. I had another plumbing issue that he wouldn't even look at...just wanted his $75 service call, for no service whatsoever and left. Later, I found that my RO system can be repaired (tank replaced) for $140. Lousy service from this company from the first phone call.
