4 Common Causes of Leaking Tanks

Water tanks are your alternative source of water when the main line goes down, so they need to be reliable and available when you need them the most. For some, rainwater tanks are even used as a mains supply. While today’s modern tanks, such as steel rainwater tanks are durable and dependable, sometimes natural causes and even human errors result in their damage. And when this damage goes unnoticed, your water tank and the water in it will become unusable.

To prevent this, you need to know the factors that cause tanks to leak. Here are some of the most common causes:

1. Rusting and cracks

The most common factor that leads to a leaking tank is the tank being old. Let’s face it. Nothing lasts forever. Even an extremely durable water tank will deteriorate over time, and this deterioration will lead to cracks and rusting. If this is detected early, it can easily be repaired. It’s important to check your tanks regularly for any signs of cracks and rusting to prevent the problem from getting worse. If you do find a crack in your tank, you may be able to repair it with a tank liner.

2. Cold weather

Extremely cold weather can lead to the leaking of the pipes near the tank. This happens because as the pipes freeze, causing them to split or for their joints to pull apart. To prevent this and protect your pipes and your tanks from leaking, it’s good to install some insulation or lagging before cold weather is expected in your area.

3. Faulty float valve

A float operating valve may control the flow of water into your tank. If you have a faulty one installed, this will cause an overflow as the tank will be filled continuously. Inspect your float valves regularly to prevent this from happening.

4. Overflow is not at the correct height

The overflow should be at the correct height particularly if you have multiple tanks lined together. If not, this may cause water to simply overflow and waste available capacity and water. Ensure you have professional advice on interconnected tanks taking into account connections at the overflows and the outlets.

These are only four of the factors that contribute to tanks getting leaks. As they say, prevention is better than the cure. So whether you have slimline water tanks or round tanks, be on the lookout for these common causes to detect any potential problems early on and avoid having to deal with a leaking tank.
