The Watts Backflow Preventer 009 is a reduced pressure zone assembly designed to prevent the reverse flow of polluted water from entering the potable water supply. This is caused, in most cases, by backflow, back-pressure, or back-siphonage, and the only thing that can prevent this polluted water from entering the water supply is a backflow preventer like the Watts Backflow Preventer 009.

The Watts Backflow Preventer 009 is made of a bronze body construction, or an epozy coated cast iron construction, with two independent check valves and check seats with a relief valve and ball valve test cocks.  The Series 009 is generally used for the protection of health hazard cross-connections, and it has a maximum working pressure of 175 psi (12.06 bar).

So, what does this all mean to the layman homeowner?

In a perfect world, every single day of every single year during the lifetime of your ownership of a business or home, water flows from the city’s potable water supply to your home or business. This works efficiently because of water pressure supplied by the city water system.  All works according to plan as long as the water pressure is higher at the source of the water supply….in other words, water is pushed from the city water supply to your building by means of pressure.

But what if that water pressure decreases?  What happens then?

If that were to happen, the water pressure then becomes higher at the receiving end, your building or home, and that mean water is forced to “backflow,” or reverse the flowing direction.

But why would that happen?  It most often happens during a fire situation where the city fire department is forced to tap into fire hydrants, greatly reducing the water pressure to the entire system.  When this happens, backflow is possible, and it is that possibility which makes a Watts Backflow Preventer 009 necessary.

Another situation where backflow is possible is during a flood.  When flooding happens, sewers backup, and raw sewage can flow into your basement.  Again, a Watts Backflow Preventer 009 can protect you from this unfortunate situation.

Never fear!  Companies like City Backflow Testing are certified and licensed to handle all of your backflow needs.  During the required annual testing of your backfow testing, companies like City Backflow Testing will check your backflow preventers to make sure they are functioning properly, and if repairs or replacements are needed, they can stop the problem before it happens.

When your family’s peace of mind is at stake, turn to quality backflow prevention with the Watts Backflow Preventer 009.
