Three Common Reasons Why Water Heater Pipes May Break or Leak


Water heaters are in near constant use because the tank must maintain a supply of hot water at all times. This heavy workload can cause the water pipes to develop a slow leak or suddenly burst.

Three Reasons Why Water Heater Pipes May Unexpectedly Fail

Traditional water heaters that have a storage tank for hot water are prone to developing certain problems that cause the heating element, tank or pipes to fail. A leaking water supply pipe may cause water to damage the rest of the water heater and the surrounding area. When this happens, it is important to contact a Las Vegas water heater repair service for an inspection and repairs.


In places where the water has a high mineral content, the water supply pipes may corrode. This can happen anywhere along the length of pipe that serves the water heater. Corrosion is also a problem at the elbow joint where the water is accepted into the water-heating tank. A failure of the connection due to corrosion is a common cause of water heater problems.

Inadequate Insulation

An insufficient amount of insulation on the water heater’s pipe is another reason why a rupture may occur. This is most common during periods of cold weather, such as a rare night when temperatures drop below freezing. An uninsulated pipe may get so cold that the water inside of it freezes. Water expands as it freezes. This expansion causes the pipe to develop a crack. When the temperature increases enough for the ice to melt, the water comes out of the crack in the broken pipe and causes a leak.

High Water Pressure

In some communities, the water pressure level may occasionally vary. A sudden increase in the water pressure may be more than the water pipe can handle. The internal pressure can crack the pipe and cause a burst of water. The water would need to be shut off at the water main in order to avoid further damage. Plumbers may need to do this at the street level if the homeowner or business owner cannot access an interior shutoff valve.
