A crew from Canada Waterproofers will conduct a camera inspection of the sewer at your property to determine the best location to install the backwater valve. Our technicians can install the valve in a day. We’ll come in, excavate where the sewer connection leaves the house, usually at the front of the house. We’ll determine then if the valve should be installed inside or outside the property. After it’s hooked up, the crew will support the pipework with gravel, back-fill and compact the ground – with a concrete finish if it’s an interior job. We’ll make sure everything is cleaned, then test the valve, so that everything is operation-ready. Remember – Canada Waterproofers has 25 years experience in the plumbing and waterproofing business, and we back up our work with a 25-year warranty.
