It’s Never a Good Time for Water Heater Replacement
Nobody wants their water heater to fail, but every one will fail unless replaced first. Most people are taken by surprise when they need water heater replacement, but it doesn’t have to be that way. By paying attention to the right details, you can avoid the unpleasantness of being without hot water longer than necessary, having an unexpected expense, and possibly avoid significant flood damage to your home. What are the signs of a failing water heater, and when should you look for them?
Is Your Water Heater Past its Prime?
Because water heaters are designed to have a limited useful lifespan, it is important to know when your unit was installed. You can often find the manufacture date on the rating label (or, on older models, decoding the serial number may tell you the manufacture date), but that may not be an accurate representation of how long the unit has been in service.
If you had the water heater put in, you might still have the receipt for the work that was done. Many companies will also put a sticker on the unit when they install it that may includes the installation date. Or, you might be able to give them a call and find out when they installed the water heater.
Once you know how long the water heater has been in service, you can take the appropriate steps to evaluate it. The average lifespan of a water heater is a subject of great debate, but if the unit has been in service at least six years, you should at least inspect it yourself, and may want to have it professionally inspected. If it has been in service more than ten years, look extra carefully for signs of trouble.
What Problems Should I Look For?
- Noticeably less available hot water or longer recovery time. If you can remember when it was no problem for everyone in the family to take showers one after the other, but now you’re all fighting to take the first shower, you might have an issue with a heater element, dip tube, thermostat, or excessive sediment buildup.
- Visible rust on and/or moisture on or around your water heater. If you see rust and water on the outside or surrounding your unit, it could be nothing, but that isn’t likely. The exterior of your water heater should be clean and dry. If the tank is rusting and water has begun seeping out, a full-blown failure that could include flood damage is impending.
- More than one service call on the unit. Repeated stop-gap measures are often a sign that a water heater is nearing the end of its life. Like an old car, the cost of repeated repairs can often exceed replacement cost while never really solving the problem.
- Metallic smell or taste to your hot water. This could be a sign that the water tank itself is breaking down and will soon fail. Best to have a professional check it out more closely in this case.
- Rumbling and other noise coming from the unit. Water heaters should be nearly silent. You might hear the sound of water simmering or the gas flame burning, but rumbling, banging, or cracking sounds are not good. If you notice any of these when your water heater is in operation, call a professional.
Is There any way to Avoid Failure?
While nothing mechanical lasts forever, there are a few actions you can take to ward off premature failure. Modern water heaters are designed to require little or no maintenance, but the following will make sure you are familiar with the condition of your water heater and give it every advantage.
- Drain the water heater every six months to remove sediment. This will also increase efficiency.
- Test the pressure relief (T&P) valve by lifting the valve’s handle and letting it snap back. This should release a burst of water into the overflow drainpipe, then the flow should stop completely. If it doesn’t, install a new valve.
- Lower the temperature setting on the thermostat(s) to 120 degrees Fahrenheit. This minimizes damage to the tank caused by overheating and protects your home’s occupants from scalding.
Use caution when working with electricity, gas, and hot water. If you are unsure of how to safely do any of the above steps, call a professional for help.
