Re: Mainline Fullport Backwater Valve

Mainline Backflow Products from Edmonton, Alberta introduced Canyon Plumbing and Heating to the "Mainline Fullport Backwater Valve" ten years ago.

Canyon Plumbing is the premier plumbing company in Western Canada. We plumb 3000+ number of homes each year for prominent builders such as Beattie Homes, Shane Homes Ltd, and Jayman Masterbuilt. We take pride in the fact that we lead the field in providing added value products for builders and homeowners.

Since using the Mainline Fullport Backwater Valve, our customers have not experienced a single sewer backup in their homes. The valve has a built in main sewer cleanout and because of this feature, it takes no longer than installing the conventional main sewer cleanout that each building requires.

Because of the low cost and added value that the valve brings to the builder along with the piece of mind it brings to homeowners knowing that their new home is protected again sewer backups, the decision at Canyon was an easy one to make: Canyon Plumbing and Heating installs a Mainline Backwater Valve in every home we plumb. We would not think of plumbing a home without this sewer backup protection.

As a rule we generally do not endorse products but we treat this valve in the highest regard as one of the most important pieces in our plumbing system, therefore, we recommend its use in all new home construction.

Should you have any questions please do feel free to give me a call I would love to talk to you.
