  • If leakage is a result of overheating, check the thermostat.
  • If it’s due to corrosion, call an expert for replacement.
  • excessive pressure can result in temperature and pressure valve leakage. If this happens, leaking valves must be replaced instantly.

#2 The water is not heating enough

Your geyser is faulty when the water temperature is not adequate (not heating enough to be precise).


Heating can be a result of the following reasons

  • When the thermostat, gas pilot, heating element, and pilot controller are faulty.
  • Circuit breaker.
  • Temperature settings.
  • Undersized water.
  • Placement of pressure valve.


Here are some possible solutions to resolve this issue;

  • Eutrophication in the storage tank.


  • A moldy or corroded anode rod is entirely responsible for liberating hydrogen. This can result in water giving out an unpleasant odor. Permanent replacement of the rod is the only way to annul this problem.
  • If your water supply is from a poor source (such as well) you are apt to microorganisms and pathogens which directly leave the water smelly. To remedy this issue, raise the geyser temperature to the highest level thereby killing the microbes naturally. No microorganisms can withstand high temperatures, hence, doing this will completely eradicate offensive odor.
  • If the geyser is kept unused for a very long time it can lead to the formation of bacteria and if those bacteria are mixed with water it will surely cause the water to stink. To remedy this, apply the latter solution written above.
