After 15 months of trouble-free operation, our Aqua-Protec sewer backflow prevention valve system starting having infrequent false triggering of a sewer backflow. After superb remote support from the device manufacturer AND Mr. Rooter, the problem was not totally resolved.
A Mr. Rooter technician came to investigate and determine the root cause of the problem. This was done thoroughly, quickly and professionally and the issue was easily resolved. Further onsite investigation also ruled out potential contributing factors such as tree roots in the main drain.
There was NO charge for this service call.
The next day the technician forwarded a copies of the videos inside the pipes taken during the visit.
All my interactions with Mr. Rooter in Ottawa have been of the utmost professionalism and honesty. I would not hesitate to call them for any plumbing job.
