Our commitment to our customers is pretty straightforward setting a new standard.
Mainline Backflow Products was established in 1997 and works with all levels of government in Canada and the United States in a dedicated effort to prevent flooding caused by sewer backups. Our new and innovative product designs have quickly captured the attention of code officials and the plumbing industry across North America making Mainline Backflow Products the professionals' choice for sewer protection.
The 'Mainline Fullport Backwater Valve', the flagship product of the company, has brought MBP several nationally recognized awards because of its normally open gate concept. In 1997 this valve won the 'Ivan R.Leger Award' as the most innovative product for that year as voted by the Canadian Institute of Plumbing and Heating.
Through the Greenskin, Faceplate, and Meter Pocket lines, Mainline is bringing the same innovative background and trusted history to building penetrations. As moisture barriers are becoming more of a concern for homebuyers and builders, these products are a highly effective and inexpensive option to protect Plumbing, Electrical and HVAC penetrations.
