Backflow is the reversal of the direction of water or sewage due to a reversal of pressure. This pressure is interrupted causing an imbalance that cn be created beyond the point of interruption, which may, under certain conditions, reverse the flow of water. If the faucet does not release that water into the air, but is instead connected directly to a source of contamination, that contamination can flow back into the water system.

If you are in need of backflow prevention, J&D Plumbing and Heating provides professional plumbing services to both public and private sectors throughout the Southern California area.
