Water discharge from the frost valve
If your system has a frost valve fitted it will be located at the bottom corner of the
collector. In temperatures that cause frost or freezing the valve will open and some water
will discharge from this valve. There is nothing that needs to be done to the valve or the
system, it is operating correctly. The water will stop discharging once the valve has
warmed enough to close again, usually as the frost clears.
Refer to section 1.5 on page 4 for more information on frost protection.
