Most people do not even know what a backflow preventer is. But they can be vital when it comes to preventing contamination to your water supply. At A-List Plumbing, we provide sewer line installation and repair service in Fremont.  We want to protect your sewer system and your water source from problems.

What is a Backflow System?

Backflow is a plumbing term used to describe the flow of water going in the direction that it is not supposed to and may be contaminated. These contaminants can often be hazardous to your water chain supply. To prevent this from happening, backflow preventers are used. There are two different types.  One is an air gap (AG), and the other is a reduced pressure valve assembly (RPZ). They function differently, but both do the job of preventing contamination and backflow from happening.

• AG – this system uses air gaps between the water supply and the place receiving.
• RPZ – with this type of system, some valves open when water is flowing forward

Ensuring a Clean Water Supply

A backflow preventer is critical to ensure a clean water supply chain that removes the possibility of contamination. Contaminated water is dangerous and can be a biohazard. This plumbing solution is one of the better ways to alleviate the worry about water contamination in your home.
