There’s no denying that an expansion tank forms a major part of a home heating system. So, when you along with your home inspector are inspecting a house that you’d like to purchase, you need to ensure that the tank is in working condition. Most boilers or heating systems heat the interiors of a house by heating the water present in it. The heating causes the water to expand and thereby put extra pressure on the heating system. But, using an expansion tank relieves this pressure because extended pressure on heating systems can be truly catastrophic including the loss of valuable lives living inside the house, especially if the boiler bursts. That’s why the role of an expansion tank in maintaining the pressure of heated water is massive.

Where Can You Find Expansion Tanks?
Professional home inspection in Orlando FL services states that generally, expansion tanks remain connected to the boilers or heating systems. So, if you can find the boiler, you’ll easily trace the path to the expansion tank. However, if you’re purchasing an old house, then you must learn that the expansion tank will be placed on the building’s top-floor or even inside the attic. Some expansion tanks come with small windows attached to their sides so that you can check the inside water level. These expansion tanks are also equipped with over-flow pipes, which disposes any extra water at a different location.
Once you locate the expansion tank, it’s time to check for any possible leaks. In case the tank is located in a dark area, then be sure to use some lighting equipment for the same, such as a battery-operated torch or a smartphone camera flashlight. Moreover, your home inspector should also check for any presence of dampness, especially near to the water pipe connections.
How To Check Whether The Expansion Tank Is Waterlogged?
Usually, an expansion tank contains about one-third of the water in it. When the boiler is turned on, more water flows into the tank thereby compressing the leftover air on the inside. When a tank is waterlogged, it will spill water through the tank’s pressure valve – every time the boiler is turned on. This leads to wastage of water since more water will be needed in place of the water that is spilt & lost. Sometimes, water valves can also be clogged due to the deposit of minerals.
One of the other symptoms of a waterlogged expansion tank includes the increase in the weight of the tank. Since expansion tanks only hold 1/3rd of water, any more water storage will lead to waterlogging. You can inspect whether the tank is empty or full by tapping on it. If it’s full, then it’s waterlogged and will make a dull sound. Half-empty or 1/3rd full tanks make a shrill sound.
