Backflow Testing & Installation
Backflow preventers protect your drinking water from contamination. Blundell & Sons Plumbing installs, tests and services backflow prevention devices for homes, businesses and facilities across Southern Georgian Bay.
Backflow happens when water flows the wrong way through your plumbing, pulling contaminants from things like irrigation systems, boilers or commercial equipment back toward the clean water supply. A backflow preventer is the device that stops it, and like any mechanical device it needs to be installed correctly and tested to confirm it still does its job.
Many municipalities require backflow preventers on commercial, institutional and multi-unit properties, along with regular testing. If you've received a notice, have a test coming due, or are adding equipment that creates a cross-connection, Blundell & Sons Plumbing can help you sort out what's needed and get it done properly, across Penetanguishene, Midland, Tiny, Tay and nearby communities.

Frequently Asked Questions
What is backflow and why does it matter?
Backflow is water moving the wrong way through your plumbing, which can pull contaminants back toward the drinking water supply. A backflow preventer is a one-way protection device that stops that from happening.
Do backflow preventers need to be tested regularly?
In many municipalities, yes. Devices on commercial, institutional and multi-unit properties typically need periodic testing to confirm they still work. If you've received a testing notice or aren't sure what applies to your property, call and we'll help you sort it out.
Do you install new backflow preventers?
Yes. We assess the cross-connection, recommend the right device and install it properly, whether it's for a business, a facility or equipment at home.
Does my home need backflow prevention?
Most single-family homes don't need a dedicated device, but some setups do, like irrigation systems or certain heating equipment. We'll give you a straight answer for your situation.
What happens if my device fails its test?
Failed devices can usually be repaired or replaced. We'll explain what failed, what your options are and what it will take to get it back in service.
