Backflow Prevention

The City of Ottawa is in the process of sending letters to property owners requiring a “Survey of Premise Isolation”.

We can perform this survey, and install all the plumbing, including backflow preventers, for hair & nail salons, medical clinics, restaurants, and other commercial and industrial establishments.

Backflow Prevention

Normally, water flows out of our taps, showers, tubs and other fixtures, because water supply pressure is maintained for this to happen.  But this pressure can be interrupted, and can “push” or “pull” water in the opposite direction.

Backflow can be prevented by the installation and maintenance of the correct type of device (assembly) in the correct location.  There are several types of backflow prevention devices…

Featured Case Studies

We have worked on all kinds of heating and plumbing projects that range from small leak repairs to new commercial installation. We are happy to assist you in any projects you may have and are willing to take custom projects. Contact us for details.

Government Rebates

The City of Ottawa’s residential sewer backups and flooding website describes typical reasons for flooding of homes, and tips on how to avoid flooding.  One of the tips is to install backwater valves.

The City of Ottawa provides rebates to home owners through the RPPP (Residential Protection Plumbing Program) to install sump pumps, storm and sanitary backwater valves.
