Geyser Replacement: Signs That It’s Time to Call a Professional Plumber

As a homeowner or tenant, it’s crucial to understand that your geyser, or hot water heater, is not designed to last forever. Like other appliances in your home, your geyser requires routine maintenance and occasional replacement. This article will take a closer look at some key signs that suggest it may be time for a professional plumber to replace your geyser.

1. Age of the Geyser

The age of your geyser can be a strong indicator of its overall health and performance. Most geysers have a lifespan of approximately 8-12 years. After this period, they often start developing various issues that could affect their efficiency. If your geyser is within this age bracket and you’re experiencing issues with your hot water supply, it could be a clear sign that you need to consider a replacement.

2. Rusty Water

Rusty or dirty water coming from your hot water taps is another common sign that your geyser might need replacement. Over time, the interior of your geyser can start rusting, leading to rusty hot water. If you notice your hot water has a rusty color or metallic taste, it could be a sign that your geyser is rusting from the inside.

3. Water Leaks

Water leaks around your geyser can signify a serious problem. Over time, metal geysers can expand when heated, leading to small fractures. Although these fractures might seal up as the water heater cools down, repeated heating and cooling cycles can exacerbate these cracks, leading to leaks. If you see pooling water around your geyser, it’s advisable to contact a professional plumber immediately.

4. Inconsistent or No Hot Water

An inconsistent supply of hot water or no hot water at all is a clear sign that your geyser may need replacement. This issue could be due to a faulty thermostat, a broken heating element, or the geyser’s diminished capacity due to sediment buildup at the bottom of the tank.

5. Noise

Over time, sediment can build up at the bottom of your geyser, hardening as the water heater continually heats and reheats. This hardened layer of sediment can cause your water heater to make rumbling or popping noises. The sediment layer can also make your geyser less efficient and cause more wear on the tank, potentially leading to leaks.

6. Frequent Repairs

If you find yourself repeatedly calling a plumber to repair your geyser, it might be more cost-effective in the long run to replace it entirely. Like any appliance, the need for frequent repairs can be a sign that your geyser is nearing the end of its functional life.

Geyser Replacement by Professionals

Attempting to replace your geyser yourself can be risky. There are many factors involved, including dealing with water and gas lines or high-voltage electricity, depending on your type of geyser. An improperly installed geyser can cause a range of issues, including inefficient operation, damage to your home, or even personal injury. It’s always advisable to call a professional plumber for geyser replacements.

Benefits of Professional Geyser Replacement

Having your geyser replaced by a professional plumber comes with several benefits:

– Expert Installation: A professional plumber has the necessary skills and knowledge to install your new geyser correctly. They can ensure your geyser is installed safely and complies with local building codes.

– Proper Disposal: A professional can handle the removal and disposal of your old geyser, which can be challenging due to the size and weight of the appliance.

– Guaranteed Work: Most professional plumbers offer warranties on their work, providing you peace of mind.
