Why is Your Hot Water Tank Leaking?

Have you been noticing a pool of water under your hot water tank? If yes, then maybe it's time you get serious about your often ignored hot water tank. If you hear a dripping sound from the tank or notice a pool of water more than often, you must immediately fix the problem in order to avoid major and costly repairs. For fixing water leaking from the tank, you must first identify its source and what is causing the leak Below are some common reasons why a hot water tank leaks.

Loose Cold Water Inlet and Hot Water Outlet Connections
The cold water inlet and hot water outlet pipes are connected at the top of the hot water tank. Loose connections of these pipes can lead to minor leaks. If not fixed, the leaks can eventually create a pool of water on the top surface of the tank and droplets may even trickle along the tank surface. Simply tightening these pipes also works.

Condensation Drips
If you notice a pool of water when the tank is first filled or during winters, you probably don’t have leaks but condensation issue. This is normal. Normal condensation from the tank pipes or a nearby appliance can lead to a small pool of water around the base of the tank. In many cases, condensation forms when cold water fills the tank. 

Faulty or Broken TPR Valve
The temperature pressure relief valve is useful in eliminating excessive pressure from the tank when water gets too hot inside the tank and in keeping the tank safe. A small tube runs from the valve to the floor to direct the leakage downwards. If the TPR valve is faulty or broken, you will notice leaks from this small tube downwards.

Leaking Drain Valve
Every hot water tank is equipped with a drain valve at the bottom of the tank that is used to drain and flush the tank. A loosely secured or broken drain valve can result in leaks from the bottom of the tank. You can easily replace the drain valve to stop the leaks.

Cracked Tank
If you don't drain and flush your hot water tank regularly, or carry out water heater tank maintenance, sediments and minerals may start getting deposited at the bottom of the tank. These buildups can result in internal corrosion of the tank. The corrosion can eventually lead to cracks or pinholes in the tank. Once a minor leak starts through the cracks or holes, the pressure of water can force it to make its way and result in leaks.

Most of these hot water tank defects can develop over the years or may occur due to poor installation of the tank.
