Common Water Heater Problems and Signs You Might Need a New Unit
Your home’s water heater is probably the most costly component of your plumbing system, and many common water heater problems are actually pretty easy to figure out and repair without the assistance of a plumber.
Temperature Problems
If your water is too hot or doesn’t seem to get hot enough, fixing the problem is usually as simple as adjusting the thermostat on the unit. For most households, the ideal temperature for hot water is between 120 and 140 degrees.
If there is absolutely no hot water coming from the tank, you could have a broken heating element (or gas thermocouple, if your device is powered by natural gas). These components are easy to replace on your own and should restore your hot water supply right away.
Noise Problems
There is nothing worse than a hot water tank that bangs, creaks, knocks, or whines. Most noise issues are caused by the sediment that can build up inside the water tank; the debris comes in contact with the heating element, which makes lots of noise as it literally burns the sediment away. Flushing the tank usually corrects this problem.
Another reason hot water heaters make noise is because the heating element may be burning out. If you have flushed out your tank and removed the sediment but are still hearing strange noises, it could be time to replace the heating element.
Time to Replace?
Here are some of the things you will need to consider in order to determine if it is time to replace your hot water heater.
- Usage and Water Quality: Obviously, hot water heaters that see a ton of usage won’t last as long as those that are only used sparingly. If you have a growing family, you can expect your hot water needs to change as your kids grow, and this can impact the life of your hot water heater. Furthermore, if you live in an area with hard water, the mineral buildup inside the tank can clog plumbing lines and may shorten the life of the unit. If either of the above applies to you and you have been experiencing trouble with your hot water heater, it may be time to replace it.
- Age: Most residential water heaters are sold with a 5-year or 10-year warranty, so a new heater should last at least that long. However, if you live in an older home with an aging hot water heater, even common problems could be an indication that it is time to replace it. A hot water heater that is more than 15 or 20 years old and is clanging or knocking, failing to produce hot water, unable to produce hot water consistently, or unable to maintain a constant water temperature has probably reached the end of its life.
- Leaking: Unfortunately, there is no quick and easy fix for a leaking hot water tank. If you notice standing water anywhere near the unit, call a professional right away – you will need to replace the tank as soon as possible to prevent flooding or other damage to your home.

Hey. Great article. But here’s the thing about thankless water heaters – there are both pros and cons to having them. While they do cost more initially, they do save money in the long run. But when you first get one, you really have to make sure it’s installed properly and that it’s the right size for your water usage needs.

Some forget how old their hot water heater is and that might lead to plumbing problems. That is why it is important to perform proper water heater maintenance.

Gas is expensive, especially right now. You have to purchase the refills and it’s not cheap. Yes, your water will heat up faster, but you will be putting more out from your wallet. I would recommend an electric water heater. There are one’s out there right now that have continuous heat which actually will save you on electricity because the water heater doesn’t have to work as hard to get you hot water. Or you can get a traditional water heater with a cover that sits over it and helps retain heat.

For that reason, you will find a solution with regards to water heating problems and you will now utilize the help of a complete service provider rather than an individual plumber. Very informative post, thanks a lot.

You should try and repair the water heater that is leaking only if you are confident of handling a wide range of problems from a leaking rubber valve to a leak in the storage drum itself. Thanks a lot for this post!

You actually make it appear so easy together with your presentation but I to find this topic to be really one thing which I feel I would by no means understand. It kind of feels too complicated and extremely wide for me. With that, I am looking forward to your subsequent blog articles!
