Backflow prevention is needed to safeguard drinkable water from being contaminated by water flowing back into the water supply. This often happens when a low pressure area is formed that affects conventional water flow.

Safeguarding Against Contamination

Its important to be aware of potential sources of water contamination around the home. These can include bendable hoses in kitchens, showers, and baths. Irrigation systems. Swimming pools and ornamental ponds.


We recommend installing a backflow prevention device to safeguard drinking water. These valves should be installed by an experienced IQP licensed professional. It should be tested and certified once a year to make sure it’s working effectively. 


The Premium team has extensive knowledge and experience in backflow prevention. Our team members are all IQP certified and licensed. We’ll make sure your home and business is safe from potentially harmful side effects of contamination caused by backflow.
