The Dangers of Plumbing Backflow

Plumbing backflow is the unintentional and undesirable reversal of the flow of water in a pipeline or plumbing system. When this happens, it creates a dangerous situation because your drinking water can become contaminated by a liquid, gas, solid or mixture. Gillece Plumbing Services can help you identify situations that can cause backflow and help to protect you and your family from the dangers of plumbing backflow.

How Does Backflow Happen?

  1. Siphonage is one way backflow can happen, in which water flow reverses due to a drop in water pressure or from negative pressure. Siphonage often happens in the event of a water main break.
  2. Back pressure is another cause of plumbing backflow, when pressure in downstream piping rises above the supply pressure, allowing downstream substances to enter your water supply. This can happen in thermal expansion, pump systems and elevated tanks.

Where Does Contamination Occur?

A cross connection is a point in your plumbing system where your water supply can be connected to an outside water supply that is unfit for drinking. Cross connections include chemical and metal processing plants and chemical injectors, irrigations systems and garden hoses that are connected to your water supply. A hose left running where there are mixed chemicals like fertilizers or pesticides is also a type of cross connection. If any of the substances from these connections, including metals and chemicals, come into contact with your water supply and the water you drink, cook with and bathe in, the dangers are obvious.

How Can Backflow Be Prevented?

A backflow prevention device can be installed on the main supply line to your property in order to protect your drinking water system from any cross connections. Backflow preventers protect your drinking water from coming into contact with any kind of questionable contaminant, even in the case of a low or negative pressure situation. A certified Gillece Plumber can ensure the proper installation and operation of your backflow prevention device, ensuring you and your family are protected. A backflow preventer should also be tested annually.
