What to do if Water Tank is Leaking?

Generally, water tanks are made from steel, metal, plastic, or concrete. To ensure their longevity and performance, you need to check the lining and structure (exterior and interior) for leaks, cracks, or holes. Mold and mildew growth, dirt, and particulates can also coalesce and develop unhygienic conditions.

To clean the water-holding container, you need to assess the problem first up. Normally, crevices can be seen on concrete tanks due to temperature differences, rust on steel tanks, or algae growth on plastic ones. To fix the issues, you need to call in experts from Lakhwa Chemical Services, one of the best companies for tank cleaning and waterproofing in Karachi, Pakistan.

Common Causes of Water Leakage

Several factors can cause a water tank to trickle; it’s important to determine the cause and take measures:

  1. Corrosion

Rusting is one of the most common causes of water leaks. Over time, different areas, such as lining, pipes, and base layer can get damaged due to deposition or mineral buildup. To remove rust from the exterior surface, the surface should be washed and coated with zinc spray and paint. If the layer is thin, use a mixture of phosphoric acid, zinc phosphate, and nitric acid. In case of pipes, use vinegar, steel wool and water to clear it.

  1. High Water Pressure

High pressure can cause cracks and leaks in a water tank. To adjust the water influx, adjust the pressure and the lock nut, and turn the water back on.

  1. Loose Connections

Water can gush forth from damaged or wobbly connections (broken pipes, loose nut, etc.). In addition, the pressure and temperature relief and drain valve can also cause leaks.
