User Answers:

  1. In plumbing terms, Backflow means the undesirable reversal of flow of liquid into the potable (or good) water supply. A a back-flow preventer is a device (installed by your plumber) which is designed to keep this Back-siphonage from happening. Points at which a potable water connects with a non-potable water are called cross connections. In plumbing design, installation and repair, such connections must be carefully prevented or reversed if they exist.

    Back-pressure can occur in plumbing when water hammer occurs (waves of water traveling / travel back and forth in the pipes) and a cross connection exists. Back pressure or back force can cause an undesirable contaminant to enter potable water piping. Sources of back pressure may be boilers, heat exchanging equipment, power washing equipment, fire sprinklers, or pumps in the water distribution system. To reduce the risk of contamination, a backflow preventer should be fitted by a licenced plumber. A back flow stream can literally cause a river of problems.   [edit]

  2. Backflow is the reversal of the flow of non-potable (bad) water or other substances through a cross-connection and into the piping of good potable water source. This is very undesirable. This can happen to two basic ways. 1) due to backpressure backflow and 2) due to backsiphonage.

    Backsiphonage is backflow caused by a negative pressure or a vacuum on the potable water system side.  [edit]

  3. Backpressure and or backflow occurs in plumbing pipes when the pressure of the nonpotable water system exceeds the pressure of the potable plumbing system side of the water system. This problem is extremely dangerous.   [edit]

  4. You should contact www.DelandPlumber.com (a licenced and state certified backflow professional) to have this determined. However, These assemblies are required to be tested upon installation, after cleaning or repairs have been made and at least annually.

    Commercial and industrial customers who have Double Check Valve Assemblies must have their devices tested semi-annually, as well as after installation and repairs or cleaning.

  5. When a new water heater is installed a backflow preventer needs to be installed into the water pipes. This will prevent water from flowing backwards, and contaminating drinking water. It stops water that has been heated from rejoining your water supply as this temperature change can also affect the pressure in your water-heater.

    It is always best to leave this installation to a
    licenced professional like the pros at www.delandplumber.com

    Your professional will fit the backflow preventer onto the water pipes before they reach the heater. The pipes should not go upwards in an incline before they reach your preventer. The backflow preventer should be only a short distance from the heater, so that it is not affected by the warmth of the heated water. Don't place the backflow preventer between a heater and an expansion tank.  [edit]
