Installation fee shall include cost of materials (coper pipes, fittings, etc.) and labor. There are three important factors in an installation process:

1. Plumbing: installation shall be performed by a well-trained & experience installer. Depend on the Water System to be installed, Falcon Stainless Steel Flex Connectors (~ $50 each) might be used to accommodate shaking in case of earthquake.

2. Code-compliace: It's important to know that Water Softener's backwashing brine must drain to a sewer system. Installer must have knowledge on cross connection in plumbing codes. Code requires a physical air gap (2 times the drainline diameter, 2 x 1/2" = 1-in gap) to prevent sewage backflow into the water conditioning system. Please read more information below.

3. Setting up the system: A homeowner can buy a Water Softener online at low price; however, without correct installation and programing knowledge, she/he may have a systen that is not working properly, use a lot of salt.   

What is a cross connection? 

    A cross connection is a permanent or temporary connection between potable drinking water and anything which can pollute or contaminate the water supply.

What is cross connection control?

    Cross connection control is, simply a program that is designed to take the safeguards necessary to protect one of the worlds most essential assets.. water.  Only through education and the combined cooperation, of the public and the water purveyor, can we insure a safe supply of drinking water.

What is backflow?

     Water distribution systems are designed to keep the water flowing from the distribution system to our customer.  However, when hydraulic conditions within the system deviate from the "normal" conditions, water flow can be reversed.  When this backflow happens, contaminated water can enter the distribution system.

What causes backflow?

     Backflow is possible in two situations, backsiphonage and backpressure.  Backsiphonage occurs when there is a sudden reduction in the water pressure in the distribution system, such as during firefighting or when a water main breaks, water flow can be reversed. This can create a suction effect drawing the non potable substance into the potable water system.  Backpressure is created when pressure in non-potable system, such as in a recirculation system containing soap, acid or antifreeze, exceeds that in the potable system pressure. This can force the potable water to reverse its direction of flow through the cross connection. Non-potable substances can then enter the potable water system.

How can backflow be prevented?

     There are several types of backflow assemblies that prevent cross connection and backflow conditions. They are:  air gap (AG) or a physical separation between the free flowing water to an open vessel, double check detector assembly (DCDA), reduced pressure detector assembly (RPDA), pressure vacuum breaker assembly (PVB) and the atmospheric vacuum breakers (AVB).

What is an air gap?

    An air gap is a vertical, physical separation between the end of a water supply outlet and the flood-level rim of a receiving vessel. This separation must be at least twice the diameter of the water supply outlet and never less than one inch. An air gap is considered the maximum protection available against backpressure backflow or backsiphonage but is not always practical and can easily be bypassed.
