Low pressure geysers, as the name suggests, do not hold pressure as it is an open system. Water is fed into the pipes through gravity feed. Should you wish to increase pressure, a booster pump can be installed along the hot water pipe which is fed from the geyser. If water pressure is low

The purpose of the mixing valve, also known as a tempering valve, is to bring down the water temperature from the solar geyser to a maximum of 60 degrees Celsius before the water comes out of your taps. This is a safety precaution, especially when there are kids around, to prevent accidental burns or

It’s probably an error in connection and need some assessment especially the wire.

It’s worn out therefore needs replacement.

It could be your element, thermostat or system controller is not working. Or a case of non-return valve malfunction. If it’s a split system also check if the circulating pump is pumping.

If it’s a high pressure then it might be your t/p valve or air release. If it’s low pressure then it could be overflow pipe or problem with the ball valve in the feeding tank. Also check the pressure valve (if overflowing then it might be worn out).
