How to Fix a Leaking Ariston Water Geyser

Understanding Why Your Ariston Water Geyser Is Leaking

Before you rush to repair your ariston water geyser, it’s important to understand why leaks occur. In most cases, a leak is caused by one of three main issues: faulty valves, loose connections, or corrosion inside the tank.

If you notice water dripping from the bottom of your Ariston water heater, it could be due to sediment buildup or a rusted tank. Sediment accumulates over time, especially if your water supply has a high mineral content. This buildup creates pressure and weakens the tank walls. On the other hand, if the leak is coming from the top, the problem may lie in the inlet or outlet pipe connections.

It’s also worth noting that Ariston water heaters are designed with a temperature and pressure (T&P) relief valve to prevent excessive pressure inside the tank. Sometimes, this valve releases small amounts of water as a safety measure. But if it’s constantly dripping, that’s a clear sign something needs attention.

Step 1: Turn Off the Power and Water Supply

Safety should always come first when working with any Ariston water heater. Before touching the geyser, turn off the electrical supply from the circuit breaker. Never attempt to fix a leaking unit while it’s powered on—it can cause electric shock.

Next, switch off the water supply to the Ariston water geyser. This is usually done by turning off the inlet valve located above the heater. Stopping the water flow prevents further leakage and gives you a chance to inspect the system safely.

Once both the power and water are off, allow the Ariston water heater to cool for at least 30 minutes before proceeding. Hot water inside the tank can cause burns or scalding if handled too soon.

Step 2: Inspect the Inlet and Outlet Connections

The first place to check for leaks is at the inlet and outlet connections. These are the pipes that carry cold water into and hot water out of the Ariston water geyser. Over time, these connections can loosen due to temperature changes and vibration.

Carefully examine the joints for visible drips or moisture. If you notice water collecting around the fittings, try tightening them gently using a wrench. Be cautious not to over-tighten, as this could damage the fittings or crack the pipes.

If tightening doesn’t solve the problem, the rubber washers or Teflon tape around the joints may be worn out. Replacing these parts is a simple and inexpensive fix that can often stop a minor leak instantly.

Step 3: Check the Temperature and Pressure Relief Valve

Every Ariston water heater is equipped with a temperature and pressure (T&P) relief valve, which is a critical safety feature. This valve automatically releases water if the pressure inside the tank becomes too high.

If you find water leaking directly from this valve, it could be a sign that your Ariston water geyser is overheating or that the pressure level is exceeding the recommended limit. First, lower the temperature setting on the thermostat to around 50–55°C. Sometimes, an overly high temperature setting causes unnecessary pressure buildup.

If the valve continues to leak even after adjusting the temperature, it may be faulty and require replacement. In such cases, it’s best to contact an authorized Ariston service technician to ensure the correct valve is installed and the heater is operating safely.

Step 4: Examine the Heating Element Gasket

Inside your Ariston water geyser, the heating element is sealed with a rubber gasket to prevent water from escaping the tank. Over time, this gasket can wear out, become brittle, or shift slightly, leading to leaks near the base of the heater.

To check this, you’ll need to drain the Ariston water heater first. Connect a hose to the drain valve at the bottom of the tank, open it, and let the water flow out completely. Once drained, carefully remove the heating element cover and inspect the gasket.

If you notice signs of cracking, mineral buildup, or corrosion, replacing the gasket is the best solution. New gaskets are affordable and can restore your Ariston water geyser to its leak-free condition.

Step 5: Look for Corrosion or Tank Damage

If you’ve checked all the fittings, valves, and gaskets, but the ariston water heater is still leaking, the problem may be more serious—internal corrosion.

Corrosion occurs naturally over time, especially in areas with hard water. The inner tank of your Ariston water geyser is protected by an anode rod, which attracts corrosive minerals to prevent them from damaging the tank. However, once this rod is worn out, the tank begins to rust from the inside.

A rusty tank cannot be repaired effectively. If you notice rust-colored water or water pooling at the bottom of the unit, it’s time to replace your Ariston water heater. Continuing to use a corroded tank can lead to leaks worsening suddenly, causing major water damage.

Step 6: When to Call a Professional

While many small leaks in an Ariston water geyser can be fixed with simple tightening or part replacement, not all problems should be handled DIY.

If the leak is internal or related to the electrical components, it’s best to call an authorized Ariston service center. Certified technicians have the right tools, parts, and expertise to repair the heater safely and restore its performance without voiding the warranty.

Additionally, if your Ariston water heater is more than eight years old, a replacement may be more cost-effective than continued repairs. Newer models are more energy-efficient, feature advanced safety technology, and are designed to last longer.

How to Prevent Future Leaks in Your Ariston Water Heater

Preventive maintenance is the key to ensuring your Ariston water geyser remains in top condition. Here are a few tips to keep it running smoothly:

• Flush the tank once every six months to remove sediment buildup.

• Inspect the T&P valve regularly for signs of dripping or rust.

• Check all pipe connections twice a year for moisture or looseness.

• Replace the anode rod every 2–3 years to prevent internal corrosion.

Regular care and periodic inspections can extend the lifespan of your Ariston water heater and prevent unexpected leaks.

Final Thoughts

A leaking Ariston water geyser doesn’t always mean you need a replacement. In many cases, small leaks are caused by loose connections, faulty valves, or worn gaskets—all of which can be fixed easily with the right approach.

By understanding the possible causes and following safe repair steps, you can save both water and energy while ensuring your Ariston water heater continues to perform efficiently. However, when in doubt, don’t hesitate to seek professional assistance. Taking quick action and performing regular maintenance are the best ways to keep your Ariston water geyser reliable for years to come.
