Protect Your Water Supply with Backflow Prevention Services

Your water supply should always be clean, safe, and free from contaminants, but without proper backflow prevention, your drinking water could be at risk. Backflow occurs when a sudden change in water pressure causes contaminated water to flow backward into your clean water supply. This can introduce harmful bacteria, chemicals, and other pollutants into your home or business. At Quality Service Plumbing, we specialize in backflow prevention, testing, and installation to ensure your water remains safe and meets all local regulations.
Who Needs

Backflow Prevention?

  • Homeowners – If your property has an irrigation system, well, or boiler, you may need a backflow preventer to protect your drinking water.
  • Businesses & Commercial Properties – Restaurants, apartment complexes, and industrial facilities must comply with strict backflow prevention regulations.
  • Irrigation Systems – Lawn sprinkler systems can allow fertilizers, pesticides, and other chemicals to enter the water supply without proper backflow prevention.

  • You receive a notice from the city or water provider requiring testing.
  • You notice a drop in water pressure or discolored water.
