Backflow Prevention



Have you ever suddenly found foul-smelling, tepid water gushing up from one or more of your drains? That’s called “backflow” and it’s a pretty serious problem that needs to be dealt with immediately. Each time backflow occurs, it drastically lowers the sanitary conditions of your home’s plumbing, putting you and your family at risk.

Fortunately, there’s an easy way to fix it. Installing a backflow prevention device will effectively protect your home against all backflow. If you need a prevention device installed, maintained, repaired, or replaced, turn to Gold Medal Plumbing and Drain today. We offer comprehensive Mississauga backflow prevention services throughout the area. Let our Mississauga plumbers help take care of your home.

Call (416) 242-6111 or contact us online to schedule a convenient appointment.


A backflow prevention device can come in a variety of forms. For residential properties, it is often a one-way valve that is installed in the home’s sewer line. As long as proper pressure is maintained, the valve remains open to allow water to flow through it. If there is a change in pressure, however, the valve shuts and prevents sewage from contaminating the home.

This simple device is enough to:

  • Keep potable water safe from contaminants
  • Prevent spending hundreds of dollars on cleaning efforts
  • Give you the peace of mind knowing your water is always clean and safe


Installing this device requires access to the sewer line, as well as specialized training. If it is improperly installed, the device could not only fail to protect against backflow, but it could also impede the proper flow of water. If you want to properly protect your home against backflow, you should trust us to handle your device installation for you.

Backflow prevention devices also need to be checked annually. Waste can build up on the valve over time, causing it to become stuck in the open or closed position. Annual maintenance ensures that the device is working properly and is free of obstruction.
