I had hired a previous plumber to put all new pipes, etc. in my reno bathroom. When the toilet was flushed, the water at the sink would run slow and sometimes come to a complete stop.
Then, the water heater broke and I had to buy a new one. So I called MacKinnon to come and install it. I decided to have them look over the other plumber's work; and they fixed the issue with the toilet and sink so the water would run correctly.
I also had a water filtering system set up by the first plumber. This system was to direct the water flow throughout all the house. Unbeknown to me he had attached it to the hot water heater instead of directing the water to flow through the entire house. I would never have known about this if I hadn't needed a new hot water heater.
This work was done about 5 years ago, so I don't remember the cost of their services - that's why I put $1. But I will say this: I have high praise for the MacKinnon boys. Everything worked perfectly after they completed the work.
