For most homeowners like you and us, any problem with the hot water system goes unnoticed unless there is the unavailability of hot water at all. Minor issues are rarely looked into and water leaks can go on unnoticed for weeks at a length. However small the leak is, chances are it will ruin your floor, the wall, and other furniture near the area of the leak. And do not forget the damages it does to your water heating system. It is prudent to fix any leaks in the pipes or in the tank of your water system and check regularly for any signs of distress to the entire apparatus. Here are a few reasons that can answer if you are wondering why is my hot water system leaking?


What can cause a leak in the system?


For any hot water installation which is regularly used, there are multiple factors that can result in a leak. It could be because of a faulty relief valve, the leak could be made due to a damaged tank or the pipes and connectors are coming loose over the years. Given ahead are a few major factors that cause a leak in a typical hot water system:

Pressure Relief Valve

The PRV works by releasing a little pressure periodically so that the whole system remains under the levels of mechanical stress it can bear. But due to dirt or grit in the water, the PRV can experience loose seals and damages. If you observe a puddle under the PRV, it should be replaced immediately.

Water Pressure

It so happens that many of us stay in apartments that have water pressure that is higher than the standard operating limits of the heating system. This means the extra pressure can force the water to leak from inside the system. You need to check and maintain the right pressure inside the system and keep regularly checking the gauges.

Loose Fittings

This is as easy to occur as it is to repair. Over time, your pipes and fittings will experience wear and tear and fatigue due to constant expansion and contraction caused by hot water. This makes the fittings and washers lose. It results in the water finding places to leak from the pipes.

Tank Damage

Cracks, fractures, fissures, and holes begin to develop in your water tanks due to corrosion. If there is an unusual level of water loss in your hot water system, the chances of it leaking from your water tank are high. Whether you like it or not, a metal tank always starts to corrode hence it is important to keep checking the tank for points of failure.


The degree of water flowing out of the system determines how big or small the issue is. If you are able to catch it early on, it is a better situation to be. Being late in fixing the hot water system can result in the whole system needing repairs instead of a single part. Hence, it is essential to get in touch with a plumber Bundaberg who can at least provide you with a professional opinion before you begin tinkering with the system on your own.
