Kobelle Plumbing is licensed for backflow testing and prevention to monitor the pressure in a water system.
When the pressure in a water system is not maintained, the risk for water to flow backward into the system and become contaminated is greatly increased. Backflow testing monitors the health and safety mechanisms designed to protect water quality. Kobelle Plumbing is certified with the updated 99 NFPA 2012 edition which includes all gas and vacuum system requirements.
The function of a backflow prevention device is to keep dirty water from pools, storm drains and other external water sources from flowing backward into clean, uncontaminated water or into your home. It also keeps any water from cross-connecting with the drinking water in your home.
Backflow prevention devices or strategies are required in most local building and plumbing codes. The most common types of backflow prevention devices are air gaps, which is a space in your water storage area that connects to your plumbing system and a check valve, which prevents water from flowing backward into your home by only allowing water to flow in one direction.
Prevention and Testing:
To prevent backflow, most water districts are required to have a backflow prevention program and plan in place, along with backflow prevention devices, where necessary according to local plumbing and building codes. Most cities and counties in the United States require yearly testing of each water district by a certified backflow testing agency.
