Answers:

  1. What is backflow plumbing
    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.

  2. Water Heater plumbing
    Most people don't go out looking for a water heater until their existing water heater fails. This is never convenient, and takes a lot of time time to look for a water heater that best fits your homes needs. Energy efficiency is a critical consideration. The wrong choice can cost you thousands of dollars over time. Explore the options with your plumber and decide what type of water heater you want - gas or electric, storage or demand, stand-alone or integrated with your heating system, etc. If you are in Deland, your plumber (Prestige Plumbing) will help you "size your heater" and figure out the proper size for your household, not just in terms of gallon capacity, but first-hour rating as well. This is particularly important with newer energy-efficient technologies.

  3. What is a cross connection?
    A cross-connection is a (unintentional) connection between a (good/clean) public water system or consumer's potable (i.e., drinking) water system and any source or system containing nonpotable (bad) water or other non drinkable substances.

    An example is the piping between a public water system or consumer's potable water system and an auxiliary water system, cooling system, or irrigation system. Backflow preventers are used to stop cross connections.

  4. What is backflow or backsiphonage?
    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.

  5. What causes backflow in a plumbing system?
    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.

  6. Am I legally required to have a back flow prevention device?
    Yes. To prevent contamination an approved backflow prevention assemblies are required by law, and must be installed in accordance with plumbing or building codes. Most health regulatory agencies require an air gap or mechanical backflow prevention assembly between the delivery point of mains water and local storage or use.

    A check valve is a basic form of backflow prevention, but often more complex devices are required because check valves are not considered to be reliable, when compared to more sophisticated devices with redundancies and reduced-pressure zones.

    In the United States, the Environmental Protection Agency (EPA) holds local water suppliers responsible for maintaining the regulatory control over potable water systems. Many states and/or local municipalities require annual testing of backflow prevention assemblies. Volusia County Florida requirements can be met with a licensed backflow plumbing expert.

  10. Should I install a Backflow Preventer on a Water Heater?
    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.
