At the end of the day everything is great with our new softener and RO system and was very happy with Integrity and would highly recommend them.
Only issue we had was the initial installer showed later than expected towards the end of the day. He didn't have time to finish the RO system, but said he wouldn't be able to anyway due to a part he did not have to split the line, which seemed a little strange, as this is a brand new house with all the pre-installs and loops. Seemed like we wouldn't need anything beyond the norm to do the install.
This was late Friday, so we did not get a call until Monday to schedule a new time to finish. Another guy (think this may have been Bryan) did come out that Monday however and he was very apologetic and went through the system from head to toe and all the questions I had. Also didn't mind our 1 year old messing with his cool tool box.
Only other comment, not really a detractor, was the sale process. Michelle did answer all my questions and was very helpful scheduling and working out the price, but I felt the more technical bits weren't quite her area of expertise, but overall she did a great job and was willing to track down any unanswered questions.
