WHAT IS BACKFLOW PREVENTION?
A term used to include all parts of the Plumbing Trade that deal with protection of the Potable Water System, (The Drinking Water System) and includes Cross Connection Control, Backflow Preventers, Installations, Testing, maintenance, Regulations, Bylaws, Surveys and enforcement.
In plumbing, the term means the reversal of the normal direction of flow in a piping System. Plumbing systems are designed for the internal liquids to flow in a desired direction, either into AND around a building, (Domestic Potable Water) OR out of a building (Sewage, Wastes or Storm products) and will flow either by force or by gravity. In the Domestic Potable Water System, water is usually under pressure (force) and will flow in the direction from high pressure to low pressure.Under certain physical conditions, water may be forced, persuaded or pulled in the undesireable direction causing Backflow. These conditions are known as Back Siphonage and/or Back Pressure.
A condition caused by the loss or reduction of the supply pressure ( to atmospheric or below atmospheric pressure) pulling in the wrong direction. This may happen when the city street main breaks or the internal piping system is shut off and cut for service or repairs.
A condition caused when the system end pressure raises higher than the supply pressure. This can happen by thermal expansion thru a boiler or mechanical means by a pump or high pressure piping systems.
CROSS-CONNECTION QUESTIONS
Yes, and this is to ensure that the valve is working properly and is a requirement on many states and cross-connection control programs. Test cocks are provided on the valve for this purpose and manufacturers are required to furnish field testing information.
The purpose of a sill cock is to permit easy attachment of a hose for outside watering purposes. However, a garden hose can be extremely hazardous because they are left submerged in swimming pools, lay in elevated locations (above the sill cock) watering shrubs, chemical sprayers are attached to hoses for weed-killing, etc.; and hoses are often left laying on the ground which may be contaminated with fertilizer, cesspools, and garden chemicals.
