What is a Hot Water Cylinder?

In essence, a hot water cylinder is a water storage tank that is designed to store and heat water in homes. This means that homes have a readily available supply of hot water for a number of domestic uses, from washing dishes to showering. 

So, how can they overflow?

Overflowing Hot Water Cylinders

Water expands by as much as 3% when heated, also known as thermal expansion. Hot water cylinders are designed to relieve this extra water via an open vent pipe or a relief valve and pipe. However, when individuals see these pipes dripping, they might block these pipes - and this is how the hot water cylinder can overflow.  

Dripping from the relief pipes is normal, so when you block these off, this actually leads to the pipe itself overflowing, causing a leak. In some cases, overflowing hot water cylinders might also be caused by corroded systems, which is why it’s important to regularly maintain and service your hot water system.
