What is a backwater valve and how does it work?
It’s a one-way device installed on your sewer line that allows wastewater to exit while preventing reverse flow during heavy rains or system overloads.
Why is a backwater valve important for Hamilton homes?
Hamilton’s aging sewer systems and heavy rains increase the risk of sewage backups. A backwater valve protects your basement from hazardous contamination and structural damage.
How do you determine the right backwater valve for my home?
Our experts assess your water table and drainage conditions to recommend the optimal valve—installing an exterior valve with concrete sealing for high water tables or a full port (ball) valve for lower water tables.
Are your backwater valves CSA-approved?
Yes, all our backwater valves are CSA-approved and installed in strict compliance with Hamilton’s building codes.
