Update. After sending this rerview, we were contacted by John at Elders. He was apologetic and made things right. He payed for the install we had completed by our local plumber that brought this to our attention. I can see this as being an isolated incident due to one employee and we will continue to call Elders to service our water system on the future. The water filter install went fine at first, but the piping in our attic was missing the Air Gap and the PTrap. We had a sewer exhaust smell in our laundry room due to an airline being duct taped to the hard pipe. When we inquired to have this corrected, the response from the salesman was, "that's how we always do the install." When someone finally came out to "fix" the issue, it was done with pvc pipe and more duct tape. We are now forced to contact a local plumber to come out and fix this issue created by Elders and also have the leaking RO water lines under the sink repaired that was also installed by Elders Pure Water. The first picture attached is the original work performed and the second two pictures are the "repair" work performed. The salesman, Joey King, promised the moon and delivered shoddy craftsmanship and excuses.
