We can schedule an in-home assessment to troubleshoot your water heater issue and get down to the root of the problem. Keep reading to learn more about the most common water heater problems that you need to look out for.

Less Hot Water

If you notice that your water heater is not producing as much hot water as it used to, you may have a buildup from the minerals in hard water. These minerals are so tiny that you cannot see them with your naked eye. However, over time they can create a sediment in the bottom of your water heater that blocks the heating element from heating your water effectively. Our team can flush out your water tank to get it heating water like you expect again. 


A water leak can happen in a variety of places around your water heater. It’s easy to think that leaks are normal since it is a water appliance, but leaks are never okay. In fact, they pose a lot of risks. If leaks happen around the valves, the leaky valve may need to be tightened or replaced. Keep in mind that you have valves at the top and bottom of your water heater, so leaks can originate from either place.


Rust is always bad news for your water heater. If rust begins developing inside the tank, it’s time to replace your entire water heater because the corrosion cannot be reversed. If you have been noticing rust on the outside of your tank, we may be able to make some repairs to slow down the corrosion process so your water heater can last longer.

Oftentimes rust begins developing on connections that lead to your water heater. If we can replace those connections, we can prevent the rust from transferring to your water heater itself. Keep in mind that if rust gets inside the tank it cannot be repaired and the entire tank needs to be replaced.

Low Water Pressure

If you have low water pressure that is only impacting the hot water in your home, there’s a chance that you have some kind of damage or blockage that is preventing a strong stream of water flow from entering your home. Of course, if you also have low water pressure when you turn on the cold water at a faucet, you probably have a problem that is outside of your water heater.

Bad Odors

If your hot water produces a bad smell, that means the bacteria has had an opportunity to spread in the water. This often happens when water sits inside the tank for too long without being cycled out. For example, this may happen if you are away from your home for an extended period of time, and do not use the water. 

You can try running your hot water until it is cold in an effort to flush out all of the negatively impacted water. But it’s also a good idea to give our team a call. We can complete a professional flush that helps destroy all of the bacteria so the problem doesn’t happen again.
