Phoenix Backflow Testing & Prevention

What Is Backflow?

Backflow is the undesirable reverse flow of water from any source into the distribution pipes of the city water system. Backflow can cause very serious problems to our drinking water.

Sometimes, there are pressure changes in the pipes that can actually cause that water to flow backwards and seep into the main water supply line. Water pressure changes are not uncommon.

Backflow can happen when there’s a break in the main water line or when a fire hydrant is in use. During these types of events, water pressure is lost and the water is no longer being pushed in a forward motion to your home and it will flow backwards into the city water lines.

When this happens, the water flowing backwards can contaminate the public drinking water supply with fertilizers, pesticides, human waste, soap from sinks, dishwashers, showers and chlorine from swimming pools and spas. That’s when a backflow prevention system does its job.  Preventing backflow.

What Is A Backflow Preventer?

Water enters your home from the city’s main water supply line. That water entering your home should only flow in one direction...into your home.  A backflow preventer is a device that’s installed on your home’s water pipes that allows water to flow in one direction but never in the opposite direction. Its only job is to prevent drinking water from becoming contaminated due to backflow.

How Does A Backflow Prevention System Work?

Backflow prevention systems are devices that only allow water to flow in one direction. It’s like a one-way gate allowing water from the city’s water supply to flow into your home’s water lines but stops water any time it starts to flow backwards into the main water supply.

At Anthony’s Plumbing, we recommend you have a backflow preventer installed anywhere incoming water and wastewater might be cross-connected. 

Newer homes may have backflow preventers on certain water lines. In order to know for sure whether your home has proper backflow preventers set up, we suggest scheduling an appointment to have one of our skilled plumbers inspect your home’s water system. If backflow preventers are needed, we will provide you with solutions to keep your drinking water safe from contamination.

At Anthony’s Plumbing we are backflow prevention experts. If you have questions or would like more information on backflow prevention, give us a call we’re always happy to help.
