Our Reviews Speak for Themselves

Adam Hess
Called Arc and spoke to John about replacing a toilet in my second floor bathroom. He was responsive, professional, clean and respectful in my home. I was impressed and have since referred him to a co-worker and a couple of neighbours. Happy to recommend his work.

I always have a hard time in Toronto to find an honest contractor who would provide a very good service and you can be certain he doesn't overcharge you for anything. Since my first call I have no hesitation in calling them again. That includes a replacement of two water heaters, for which I had to call John twice after they installed them. John came ASAP to fix the heaters' connection even though I had problem with electrical connection, which was not related to plumbing of water heaters.

Backflow Preventer Device Testing ensures Compliance with the Law

In the wake of the Walkerton Tragedy the Province of Ontario created the Safe Drinking Water Act. As a result, many municipalities crafted new bylaws to protect the water supply. These bylaws now hold property-owners and tenants responsible for ensuring that their internal systems cannot backflow into the water supply, causing cross-contamination and illness. A backflow preventer device, sometimes called a check valve, isolates the municipal water supply from the building water system keeping the water supply safe.

Municipalities that have passed Backflow Prevention bylaws, or Water Supply Bylaws mandating the inspection and proper use of backflow preventers include:

All installations of the premise isolation devices and all related items should be done in accordance with the Building Code, Canadian Standards Association (CSA) -B64 series standard, Municipal Code Chapter 851 and manufacturers specifications.
