Residence inspectors reckon that badly mounted or malfunctioning hot water geysers are one of the most usual issue they come across when doing house inspections. Below are some geyser issues which you the homeowner may run into.
Leaking geyser overflow
Geysers often leak (drip) with the pressure control valve overflow pipeline. This is normal as the water in the hot geyser heats up and also cools. Nonetheless, anything greater than a couple of litres a day normally suggests that the control valve is malfunctioning. This valve must be replaced if there is a consistent steady drip from the overflow pipeline. An occasional dripping after water has been drawn from the geyser is fine.
Overheating: Steam or warm water leaving from the overflow
Geyser thermostats are specially made to fault in the open or “off” position. If the thermostat does this the water in the geyser certainly ceases to heat. Nonetheless, often the thermostat faults in the “on” position, in which the water will at some point boil as if the geyser will explode.
An indicator that this is happening is when warm water as well as heavy steam is observed coming out of an overflow pipeline. This leaving hot water and heavy steam shows that the temperature level and pressure shutoff (TP shutoff) is launching warm water because extreme temperature as well as stress is developing in the geyser. The most common reason for getting too hot is a faulty thermostat. This is possibly extremely unsafe and needs to be attended immediately. If you encounter this, switch off the hot geyser and call a plumbing professional.
Water leaking via the ceiling
This indicates that the geyser has either burst, or a significant leakage has developed, and the drip [tray as well as overflow system (if there is one) is not coping. Instantly turn off the power supply and also the cold water supply to the geyser. Switch off the geyser power at the main switch board. Call a plumber.
No warm water
Check whether the geyser circuit breaker on the main distribution board has actually tripped. Just reset the circuit breaker once or twice. If it continues to trip, call an electrical expert. If the power supply is ALRIGHT, but there is no warm water – it indicates that either the thermostat or the element are faulty. The thermostat and heating element need to be changed together. Call a plumber to do this.
Water not hot enough
This suggests that the setup on the thermostat is too low, or that the thermostat and/element is malfunctioning. Set the thermostat to 65 deg. C – a greater temperature level setup is not suggested. If the geyser is old it might be calcified and become ineffective. In this instance think about replacing the geyser.
Constructors and plumber face challenges with low warm water pressure from the geyser to the guest houses
A number of things can cause reduced hot water pressure. These include old, blocked galvanised pipes, or a filthy or obstructed 15mm flexi connector. Some residences still have old low pressure geysers – only 100 kPa – as opposed to modern high pressure hot geysers – approximately 600 kPa like the geyser wattage. Low pressure hot geysers typically have round “Lacto” valves in place of the modern pressure balancing valves. A pressure balancing valve, fitted on the cold water supply to the geyser, makes sure that both the hot and cold supply of water to the washrooms are at the exact same pressure ranking as the high pressure geyser.
