If you have been having issues with your hot water, then you might be dealing with a pretty serious problem in your plumbing. Some of these problems can be easy to fix on your own if you know where to look, while others may require the aid of a professional. To help you figure out whether you need the aid of a pro, here are some of the reasons why you might not have any hot water:
No Power to Your Water Heater
You first want to take a look at your hot water heater. Specifically, you want to check whether or not power is actually reaching the water heater.
You should be able to identify pretty quickly whether the heater is turning on in the first place, since it will be cold to the touch if it isn't getting any power. If you think that it lost power recently, then the tank could remain warm for quite a while, since water tanks have very good insulation.
Once you have determined that the heater is not turning on at all, you want to take a look at the circuit breaker and the power line to the water heater.
The switches on the circuit breaker are easy to check, but if a switch was flipped, then you want to figure out why that happened so that you can prevent a similar situation in the future. If you are overdrawing power in that section of your home, then you need to buy appliances that use less wattage or move some appliances from that part of your home.
The power line shouldn't be worn or frayed, so if you do notice anything wrong with the cord, then that might be the cause of your problems, in which case you should get a replacement.
Broken Heating Element
The heating element in your water heater might be broken, which would prevent heat from actually reaching the water in the tank. If that happens, then the water in the tank will be cold, which means that turning on the hot water in a shower or sink will just result in cold water flowing out.
Checking the heating element can be fairly difficult, especially if you haven't worked on your water heater in the past. You'll need to open up the side of your heater and test the element with a multimeter. If you don't feel comfortable doing that, then you might want to hire a professional, like Pompeii's Plumbing & Heating, to come out and take a look.
