Backflow preventers

Backflow preventers are required to protect water users from potentially being exposed to chemicals or other substances that could enter public water supplies through lawn sprinklers

Our technicians, as certified and registered backflow testers, will bring the specially calibrated testing devices required to re-certify the backflow valve at the completion of the job.  San Francisco plumbers can provide all of the services needed for your backflow so that you don’t need to call multiple contractors.  Our complete service saves you valuable time and money.  Call us today.

Backflow is the reversal of the normal and intended direction of water flow in a water system. Devices and assemblies known as backflow preventers are installed to prevent backflow, which can contaminate potable water supplies.
 Plastic Backflows are Affordable and Easy to Maintain

The new materials and designs available today make maintenance of composite devices far easier, and less expensive, than devices of the past. Often an entire assembly can be replaced for less than the cost of one of the parts making up the assembly in older models. Overall, the lifetime cost of a plastic backflow is far less than in the Brass designs of the past.
