The term "Cross-Connection Control" is essentially is referring to backflow prevention. The definition of a Cross Connection is "A cross connection is the actual or potential connection between a non-potable substance or source." Local authorities will dictate what types of backflow preventers may not be used depending on the backflow risk and health hazard. Sewer, irrigation, wastewater and residential are the main areas. There are two types of backflow, the first is back pressure where the pressure in the downstream piping is greater than the supply pressure, this is caused by a pump or elevation of water in a high rise building, the other type of backflow is back siphonage which is caused by sub-atmospheric pressure in the water system piping.

ReadyTemp® delivers the very best in hot water comfort, convenience and savings by eliminating numerous costly, comfort robbing  inefficiencies found in today's circulators, recirculators and on-demand systems. The inability to control both hot and cold water comfort, the inefficiency of continuous running pumps, the inaccuracies from pipe clamp-on temperature sensors and the costly waste of energy from repeated siphoning water from the hot water line to name a few.   Our philosophy, the sooner hot water is received at your desired temperature, the sooner very cold city water stops filling your water heater--water that would go down the drain, wasted.  ReadyTemp®'s temperature dial provides homeowners the means to control and optimize their home’s hot water convenience and comfort for maximum efficiency and savings.

Industry record efficiency; intelli-Circ on-board microcontroller, cyclic-pumping, anti-siphon solenoid prevents costly HW demand

ReadyTemp® monitors temperature using a "precision grade" stainless steel "water contacting" temperature probe. It consistently and accurately measures temperature, cycling the internal TACO pump, only as needed, maintaining water at the homeowners dialed-in temperature.  ReadyTemp®'s unique space-industry engineered manifold achieves ‘positive bypass flow restriction’ using an integrated ‘normally closed’ solenoid valve for industry-record efficiency and savings.  This more efficient bypass valve prevents any water from siphoning out of the hot water line and into the cold water line during the homeowner’s use of cold water inside or outside of the home.  Inefficient ‘normally open’ thermostatic bypass/comfort valves remain open any time 95F or hotter water is not present in the line resulting in repeated, unnecessary and expensive demand on the water heater. This costly, inefficient siphoning occurs as a result of the imbalance in water pressures between the hot and cold water lines during cold water use. Higher pressure in the hot water line forces water into the cold line, even during the use of cold water only. This siphoned water is then replaced by cold city water entering the home’s water heater. With Inefficient hot water recirculators, every instance of cold water use, whether at the kitchen tap, the bathroom toilet, or the garden hose, results in extra demand on the water heater.

Atmospheric Vacuum Breaker - Model GFAVB - The atmospheric vacuum breaker is one of the least expensive backflow prevention assembly. The GFAVB is a non-testable unit and are good for back siphonage only for non-health hazard or health hazard conditions. They must be installed downstream from any shut off valves and cannot be under pressure for more than 12 hours. If an GFAVB is used backflow prevention on a irrigation system you must install one GFAVB after every valve for each zone in the system. It must also be installed at least 6 inches (150 mm) higher than the highest outlet in the system (some GFAVB manufacturers, and some local officials, require that they be installed 12 inches (300 mm) higher than the highest outlet). Some municipalities do not allow the use of GFAVB’s. These units will NOT prevent backflow pressure and can only protect against back siphonage.

Various types of backflow preventers exist for different applications and health hazard conditions, check state and other local administrative codes or other regulation on the correct backflow to use. The following backflow preventer types are available in all sizes:

Dual Check Valve - Model GF8080, GF8080E - The Dual Check Valve or double backflow prevention valve is basically a stripped down Double Check Valve without shut off valves and test cocks. They are non-testable and are typically used by water companies and installed after a water meter to prevent the meter from running backwards and low protection against backflow. This piece of equipment is the center of controversy with many backflow authorities and should never be confused with Double Check Valves. Check with local authorities for required installation, as most do not recognize these as backflow prevention devices.

ReadyTemp®'s temperature-based cyclic system pumps water that is lower than the homeowner’s selected temperature out of the hot water line, into the cold water line, and then back into the water heater.  This cyclic-pumping consumes less energy compared to top-mounted hot water recirculators which pump continuously during scheduled-on periods.  Cyclic pumping benefits comfort as well by providing a home’s cold water pipes the seconds needed to absorb the warmer water that has been passed from the hot water line.  As a result, the homeowner does not waste water, time and energy waiting for cold water, a frequent complaint by owners of other hot water circulation pumps.   ReadyTemp®'s normally closed solenoid valve provides unsurpassed comfort in that it's not vulnerable to pressure fluctuations during cold water use, unlike inferior thermostatic valve and spring-based check valve designs that cannot prevent siphoning from the hot water line during cold water usage.

Backflow is the undesirable reversal in the flow of water from a real or potential source of contamination back to the potable (or clean) water supply. Consider having a garden hose in a bucket of soapy water at your home, and having backflow event occur causing that soapy water to "backflow" into the drinking water portion of your home. Various types of backflow preventers exist for different applications and health hazard conditions, check state and other local administrative codes or other regulation on the correct backflow to use. The most common are reduced pressure backflow preventer and double check backflow preventer valves. Backflow preventers are primarily used in sewer, wastewater, residential backflow preventer, sprinkler and irrigation backflow applications.
