Kevin the plumber who showed up was a great and dedicated guy. he diagnosed the problem correctly and it was not a usual and easy issue. He gave me feedback but I used a different alternative to resolve the issue.

We had Ryan in the Sarnia-Lambton area. He was fabulous. He came out on a Friday, but we needed the town to fix their meter issues. Ryan even followed up with the town and us the Monday following. Highly recommend!!
