 No, we had them put in, but it was some years ago, so I don't know if a warranty would still be covered. Well, at least reach out to the contractor. Maybe in good faith he'll call you back. But apart from getting a hold of the people that know that product the best, I would say they can be replaced, but I don't know that product that well, other than it sounds to me like there's a lot of people saying they're not doing their job.
