Common Water Tank Problems and How to Fix Them

Posted on: Aug 14, 2025

Choosing the best water tank in India is a great start to ensuring a safe and steady water supply—whether at home or in a commercial space. But even the most durable tanks can face issues over time. Improper maintenance, poor installation, and environmental factors can all take a toll.

The good news? Most water tank problems can be fixed easily if you know what to look for. Let’s break down the most common issues, their causes, and practical solutions to keep your water clean, fresh, and safe.

1. Algae Growth Inside the Tank

The Problem:

If sunlight seeps into your tank, it can encourage algae growth—a green, slimy layer that makes water taste and smell unpleasant.

The Fix: 

• Choose a UV-protected, food-grade drinking water tank. 
• Always keep the lid tightly closed (a threaded lid works best). 
• Clean the tank at least twice a year with a safe disinfectant. 

2. Cracks or Leaks

The Problem: 

Cracks often appear due to poor installation, pressure on the tank, or manufacturing defects, leading to water wastage. 

The Fix:

• Use a sealant made for plastic or polymer tanks for small cracks. 
• For major damage, replace it with the best water storage tank in India for long-term reliability. 

3. Foul Smell or Bad Taste

The Problem: 

Bacteria, stagnant water, or debris can give your water an unpleasant smell or taste. 

The Fix: 

• Flush and clean the tank regularly. 
• Install a water filtration system to block impurities. 
• Use only food-grade tanks to avoid chemical contamination. 

4. Sediment Build-Up

The Problem: 

Over time, dirt and debris settle at the bottom, affecting water quality and clogging pipes. 

The Fix: 

• Schedule professional cleaning every 6–12 months. 
• If you use rainwater harvesting, install a first flush diverter to block debris.  

5. Overflow and Spillage

The Problem: 

A faulty float valve or neglecting water levels can cause overflowing—wasting water and possibly damaging nearby areas. 

The Fix: 

• Replace faulty float valves immediately. 
• Consider installing an automatic water level controller. 

Pro Tips to Prevent Tank Problems

• Pick the best water tank in India—UV-protected, food-grade, and multi-layered. 
• Inspect the tank regularly for cracks, leaks, or discoloration. 
• Keep the tank completely covered and away from direct sunlight. 
• Ensure professional installation to avoid long-term damage.
