Backflow Preventer Installation & Testing in Huntsville, Alabama

A backflow preventer is a plumbing device used to prevent the reverse flow of water in a plumbing system. Ensuring that water flows in only one direction in the plumbing system is essential to prevent contamination of the whole water supply.

When Is a Backflow Preventer Needed?

A backflow preventer is typically needed in homes or businesses where there is a risk of contamination of the water supply. This risk is common when there is a potential for backflow. A backflow occurrence can happen due to changes in water pressure or from cross-connections between drinkable water and non-potable water sources.

Here are some situations where a backflow preventer might be needed:

• Irrigation Systems: Properties with irrigation systems, particularly those using fertilizers or pesticides, should have backflow preventers to prevent contaminants from being drawn back into the main water supply.
• Commercial Properties: Businesses such as restaurants, car washes, or industrial facilities that use chemicals or have specialized plumbing systems may require backflow preventers to protect the water supply from contamination.
• Alternative Water Sources: Properties with alternative water sources like wells, rainwater harvesting systems, or greywater systems should have backflow preventers to prevent contamination.
• Hazardous Areas: Any location where there is a risk of backflow contaminating the potable water supply, such as near chemical storage areas or sewage systems, should have backflow preventers installed.
• Boilers or Heating Systems: Buildings with boilers or heating systems that are connected to the water supply may require backflow preventers to prevent contamination from chemicals or corrosion inhibitors used in the heating system.

Our Backflow Preventer Testing Services

Similar to any plumbing system, backflow preventers can wear out over time or develop faults, which can compromise their main job of preventing contamination. That’s why it’s essential to have your backflow preventers tested regularly to ensure the purity of the water you’re consuming.

Our experienced plumbers at Blake Brothers can inspect and test your backflow preventer, ensuring that everything is flowing smoothly and in the right direction. For backflow preventer testing in Huntsville, contact Blake Brothers.

Backflow Preventer Installation Services

Installing a backflow preventer involves strategic consideration to ensure proper functioning and compliance with city and state health regulations. Our team can assess the specific issue within your plumbing system and carefully determine the level of protection needed. Here are some of the main types of backflow preventers:

Pressure Vacuum Breaker (PVB):

• PVBs are often used in residential irrigation systems and outdoor hose bibs.
• They provide protection against backflow by allowing air to enter the plumbing system when pressure drops, preventing water from flowing backward.

Atmospheric Vacuum Breaker (AVB):

• AVBs are commonly installed on individual plumbing fixtures, such as outdoor hose bibs or laundry faucets.
• They rely on atmospheric pressure to prevent backflow, sealing the inlet when there is a drop in pressure.

Dual Check Valve (DCV):

• DCVs are simple backflow preventers with two check valves and are often used in low-hazard residential applications.
• They provide basic protection against backflow and are suitable for use on individual plumbing fixtures, such as kitchen sinks or bathroom faucets.
