Within the combined valve is built a special controller which during water heater normal
operation allows the expanded during heating water not to leak through the valve side hole, but
to pass into cold water plumbing. The quantity of this water is negligible and usually is with low
temperature. During normal operation of the water heater, as well as in present of additional
return valve, it is possible that through the side hole of the valve drips some water drops. This
should not be perceived as defect and the side hole of combined valve should not be blocked
because it shall cause destruction of the tank. The built-in controller in the valve prevents, in
case of cutting water supply, the water in the water tank to return to cold water pipeline.
CORROSION PROTECTION, PREVENTION, MAINTENANCE
Enameled water heater tanks. In the water tank is installed additional corrosion protection. It
consists of an anode protector (anode) of special alloy operating only when the water tank is
full. During its wear the anode is providing additional protection to the internal water tank from
corrosion. The level of anode wear depends of used water quantity and quality. Its average
operation life is 5 (say: five) years. After this period, a manufacturer authorized specialist or
