About us
Ottawa-wide guidance, close to home.
We help homeowners across all regions of Ottawa understand backwater valves, sewer backups and basement flood prevention—without jargon or one-size-fits-all answers.
Who we are
Useful information for every part of Ottawa.
Backwater Valve Ottawa is a homeowner information resource. Our guides are written for people across central, east, west and south Ottawa, from Orléans and downtown to Kanata, Barrhaven and the surrounding communities. We explain the basics, share area-specific context where it has been checked, and point you to current City sources when local rules or programs may change.
This is educational coverage, not a claim that one contractor serves every address. If you would like to ask about your own home, contact requests are emailed to Lister Plumbing for follow-up; availability and service are confirmed separately.
