Components of Your Backflow Prevention System
Your backflow prevention system is made up of several key components, each playing a crucial role in preserving the safety of your water supply. One important element is the valve, which is designed to allow water to flow in only one direction, preventing contaminated water from flowing back into your clean water lines. These valves, often made of durable materials like brass or stainless steel, are engineered to withstand constant pressure and varying environmental conditions. Additionally, backflow prevention systems may include air gaps, which act as a physical barrier between the water source and potential contaminants, providing an extra layer of protection.

This company is great and does amazing work! We needed a new way to vent our older boiler and water heater before the freeze. We had no hot water or heat! Steve and Alex came out, talked through our needs, and set us up nicely.

Lambert has been our plumber and HVAC professional since we bought our house 15 years ago. In that time, we have expanded and upgraded our equipment. I cannot recommend them more highly. They are problem solvers and go above and beyond expectations.
