An overhead storage system plays a critical role in ensuring uninterrupted water supply in homes, apartments, and commercial buildings. Overhead tanks are constantly exposed to changing weather conditions, regular usage, and long-term wear. Over time, this can lead to several issues that not only affect water quality but also reduce efficiency and lifespan. Understanding these common problems and knowing how to fix them can help you avoid costly repairs and health risks.
1. Leakage and Seepage
One of the most frequent problems people face is leakage. Small cracks, loose fittings, or aging material can cause water to seep through the tank walls or base. This not only leads to water wastage but can also weaken the building structure.
How to fix it:
Inspect the tank regularly for visible cracks or damp patches. Minor
cracks can be sealed using waterproof sealants, while severe damage
may require professional repair or replacement. Ensuring proper
installation and timely maintenance goes a long way in preventing
leaks.
2. Poor Water Quality
A neglected watertank often becomes a breeding ground for bacteria, algae, and other microorganisms. Dust, insects, and debris can enter through uncovered or damaged lids, contaminating stored water and posing serious health risks.
How to fix it:
Clean the tank at least twice a year using safe disinfectants. Make
sure the lid is tightly sealed and vents are properly covered with
mesh to prevent insects and dust from entering. Regular cleaning
ensures safe and hygienic water for daily use.
3. Overflow Issues
Overflowing is a common yet avoidable issue. Faulty float valves or incorrect water level settings can cause continuous overflow, leading to water loss and damp walls around the tank area.
How to fix it:
Check the float valve periodically and replace it if it is worn out
or malfunctioning. Installing an overflow pipe that directs excess
water safely away from the structure can also help prevent damage.
4. Algae Formation
When overhead tanks are exposed to direct sunlight, algae growth becomes almost inevitable. Algae not only discolour the water but also produce unpleasant odours and affect taste.
How to fix it:
Use opaque or UV-resistant tank materials to block sunlight. If algae
have already formed, drain the tank completely and scrub the inner
walls thoroughly before disinfecting it. Keeping the tank covered at
all times helps prevent regrowth.
5. Structural Damage Over Time
Constant exposure to heat, rain, and pressure can weaken the tank body. A poorly maintained water tank may develop bulges, cracks, or base instability, increasing the risk of sudden failure.
How to fix it:
Ensure the tank is placed on a strong, level platform. Avoid
overfilling beyond recommended capacity. Regular inspections can help
detect early signs of structural stress so corrective action can be
taken before major damage occurs.
6. Foul Smell from Stored Water
Unpleasant odour is often a result of bacterial growth, stagnant water, or decaying organic matter inside the tank. This issue is more noticeable when water is stored for long periods without circulation.
How to fix it:
Drain and clean the tank thoroughly. Flush the connected pipelines as
well. Periodic usage and proper cleaning schedules help keep stored
water fresh and odour-free.
7. Blocked Inlet or Outlet Pipes
Sediment, rust, or debris can clog inlet and outlet pipes, affecting water flow and pressure. In some cases, this can even damage connected plumbing systems.
How to fix it:
Remove and clean the pipes periodically. Installing a simple filter
at the inlet can reduce the amount of debris entering the tank.
Proper filtration also improves overall water quality.
8. Lack of Regular Maintenance
Many issues arise simply because routine checks are ignored. Overheadtanks that are not maintained regularly are more prone to leaks, contamination, and mechanical failures.
How to fix it:
Create a simple maintenance schedule that includes inspection,
cleaning, and component checks. Timely attention can prevent small
problems from turning into major repairs.
Conclusion
A well-maintained water tank ensures clean water, better efficiency, and long-term reliability. By identifying common problems early and taking corrective measures, you can protect both your water supply and your home structure. Regular cleaning, proper installation, and periodic inspections are the keys to keeping your storage system safe and functional for years to come.
