Most Common Geyser Problems

No Hot Water?

The following inspection should be
made:

Not Enough Hot Water?

Refer to the table to determine the
amount of water used per bath.

No Water Comming from Hot Water
Taps?
|
Check that there is water supply to
the electric water heater.
All modern water heaters operate on a push through system, i.e. water can only be drawn off if cold water is introduced to it. |
Continuous Overflow of Water
from Hot Water Installation?

Exactly where overflow is released
from:
The SABS colour codings are as
follows:
Yellow = open vent cistern tank type, i.e. no pressure Blue = 100kPa closed system Black = 200kPa closed system Red = 400kPa closed system Green = 600kPa closed system If water drips from the expansion relief, try and determine the volume of water. Water expands when heated and the volume of expanded water is directly proportional to the size of the geyser and the thermostat setting. Expansion can vary approximately 10% of the volume of the geyser per day. If the volume expanding exceeds this, establish whether the house has balanced pressure. The term "balanced" refers to the cold water take off after the pressure reducing valve. In an unbalanced system where common tap mixers or appliances are using hot and cold water simultaneously, cold water may tend to force the hot water back into the line which in turn will over pressurise the electric water heater and cause the expansion relief to flow. The combined expansion relief pressure reducing valve can be serviced with replacement parts in the event of excessive release of water. The separate expansion pressure reducing systems are not generally serviced with replacement parts. Once again the expansion relief overflow and the safety valve outlet must be piped to the outside by means of metallic pipes, and insulated where freezing can occur. |
