Cisterns and water tanks are vital for maintaining a continuous water supply in homes, industrial facilities, and agricultural operations. However, as time passes, these tanks can suffer damage from factors such as corrosion, mechanical impacts, weather conditions, or improper use. Regular maintenance and prompt repairs are crucial to prevent significant accidents and financial losses.
Common Cistern Problems and Their Solutions
- Corrosion
One of the most common problems in metal tanks is corrosion. Water, especially if it contains salts or chemicals, can cause oxidation of the tank walls. To prevent the destruction of the cistern:- Clean the affected areas of rust.
- Apply an anti-corrosion coating to protect the metal from further oxidation.
- Regularly inspect the tank and perform preventive painting with special materials.
- Cracks and Leaks
Cracks can occur in both metal and plastic cisterns due to temperature fluctuations or mechanical damage. To fix these issues:- Detect the leak by visual inspection or using water tests.
- For metal tanks, use welding or special metal patches for sealing.
- For plastic tanks, use epoxy resin or specialized repair kits for polymers.
- Contamination
Over time, dirt, sediment, or algae can accumulate in tanks, affecting water quality. To solve this problem:- Regularly clean the internal walls of the tank.
- Use special antiseptic agents to disinfect the water and internal surfaces of the cistern.
- Install filters to prevent dirt and foreign particles from entering the tank.
- Clogged Pipes or Valves
Sometimes the issue is not with the tank itself but with the water supply system. If pipes or valves are clogged, this can interfere with the normal operation of the tank. In such cases:- Check and clean all the pipelines connected to the cistern.
- Ensure the valves are functioning correctly and do not block the water flow.
Tips for Cistern Maintenance
- Regular Inspections. Periodic visual inspection of the tank helps to detect corrosion, cracks, or leaks in time.
- Freeze Protection. If the cistern is used in cold conditions, it should be insulated or fitted with heaters to prevent water from freezing.
- Water Level Control. Use water level sensors to avoid overflows or drying out the cistern, which could damage its walls.
When to Call Professionals
Some issues can be addressed independently, but in cases of severe damage or when the cistern requires specialized repairs (such as welding or replacing large sections), it’s advisable to seek professional help. Experts can assess the tank’s condition and restore its functionality with minimal risk.
Proper repair and regular maintenance of cisterns are essential for prolonging the tank’s lifespan and ensuring a reliable water supply.
