No one likes taking a cold shower, especially not when they’re in the middle of a hot shower and then it becomes a cold shower. Gradual or sudden drops in hot water output is a common problem for water heaters, and an incredibly frustrating one. There are a number of different possible causes for this issue, all of which will require professional repairs. Let’s take a look at a couple of the possible causes for drops in water heater output.
Broken Dip Tube
The dip tube is the part in the water heater that directs all incoming water to the bottom of the tank. There are two reasons for this. One, the bottom of the tank is where it’s hottest, and two, if cold water flowed directly into the top of the tank it would make it to you before it could be heated properly. A sudden blast of cold water in between stretches of otherwise hot water is a sign that the dip tube might be cracked or otherwise broken.
Over time, small amounts of minerals collect on the bottom of the water heater tank, due to the variable hardness of the water flowing through it. If not cleaned out on a fairly regular basis, these minerals can build up into deposits. Eventually, the deposits can become so thick that they actually insulate the bottom of the tank from the heat from the burner assembly. This prevents the water inside from being properly heated, which is why you may have tepid or cold water flowing out of your tap. The way to solve this is to scrape the sediment deposits out of the water heater tank.
