Backflow Prevention Solutions for Your Home & Business.
What is Backflow?
Backflow is the undesirable reversal of the flow of water or mixtures of water and other undesirable substances from any source (such as used water, industrial fluids, gasses, or any substance other than the intended potable water) into the distribution pipes of the potable water system. Backflow occurs as a result of a “cross-connection” within the water system, which exists when there is any actual or potential connection between a potable water system and any other source or system through which it is possible to introduce into the potable system any used water or other substance.
San Francisco backflow prevention devices are used to protect residential and commercial water supplies from contamination or pollution. Many types of backflow prevention devices also have test cocks so that they can be tested or examined to ensure that they are functioning properly. At Discount Plumbing San Francisco our San Francisco plumbers can ensure your backflow preventer is working properly, or provide a back flow install to help you protect your home and family from contaminated water.
