According to a TV9 Gujarati report, a geyser becomes an extremely essential appliance to get hot water for bathing as well as washing utensils during the winter season. In such a situation, if the warning signs from the geyser are ignored, problems like sudden stoppage of water supply, fear of water leakage, or even a major explosion can occur. Detailed information about 5 major signs indicating whether a geyser needs to be replaced in time is given here.
The first sign in this list is water leaking around or from beneath the geyser. Due to long-term use of the geyser, water can leak due to rusting, cracks, or holes developing in the tank. Apart from this, loose connections, a faulty drain valve, or condensation can also be responsible for this type of leakage, so it is extremely essential to get the unit properly inspected by an expert technician in this regard.
The second important sign is that when cold tap water comes out completely clean, but upon turning on the hot tap, impure water of yellow, brown, or rusty color comes out. This type of problem is a clear sign that rust has developed on the inside of the tank. Generally, an anode rod is used to prevent rust in tank-style gezers, and replacing this anode rod from time to time can extend the life of the unit. However, even after checking the anode rod, if no improvement is seen in the water quality, it must be understood that the geyser tank itself has gone bad.
As a third sign, unnatural or strange noises start coming from the geyser while heating water. Such noises are generally produced due to the accumulation of minerals and sediment at the bottom of the tank. Cleaning the tank can solve this noise problem, but if these noises persist in an old unit, it is much advisable to replace the water heater.
The fourth sign is if the water starts taking much longer than usual to heat up. This situation can arise due to accumulation of minerals in the tank, a sudden increase in water consumption in the house, or a fault in the thermostat or heating element. If the water heater takes a lot of time to heat water or faces frequent troubles, the advice of an expert technician must certainly be sought.
The fifth and final sign is that if repair costs start occurring frequently, purchasing a new unit is recommended. Generally, the lifespan of a tank-style water heater is up to 10 to 15 years, while tankless water heaters can remain operational for more than 20 years.
