4 Signs You Need to Start Shopping for a New Water Heater

Water HeaterReplacing a major home appliance is never fun or convenient, but the experience can go just a little smoother if you can start preparing for such a major purchase before things head totally south.

So if you're suspicious that your water heater may be on the road to failure, check out this list to see if your unit's symptoms match up with these 4 signs that your water heater might be giving up, and plan ahead for a replacement:

Signs Your Water Heater is on the Outs

#1.) It's 10 Years Old or OLDER

If your water heater is more than 10 years old, it's time to start looking for a new water heater. If you aren't sure how old your unit is, you can discover its birthday by checking out the first 3 characters of your serial number.

So, let's say your serial number is "J114881793." The first character (J) will tell you the month your hot water heater was manufactured; since J is the 10th letter in the alphabet it corresponds with the 10th month of the year, which is October. The following 2 characters (11) indicate the year 2011... so "J11" means your water heater was "born" in October 2011. Anything older than 06 may be heading for a leak or failure.

#2.) Your Hot Water is Coming Out Rusty

If you turn on the hot water in your home and it comes out rusty and metallic, that's a telltale sign your water heater is basically rotting away from the inside out. But, before you jump the gun and buy a new unit, there's an easy way to make sure the rust is actually coming from your water heater and not just your pipes.

To check, VERY carefully drain 3 5-gallon buckets worth of water from your water heater (again, be VERY careful because the water will be extremely hot); if by the third bucket the water is still coming out rusty, the problem is not your pipes.

#3.) Your Unit Makes a lot of Noise

We've explained to you before that you need to regularly flush out your water heater because if you don't, sediment will build upon the bottom of the tank until it hardens. This solid mass of buildup will not only create banging and rumbling sounds — which are essentially your water heater's cries for help — but it will also keep your unit from running efficiently and potentially cause leaks.

#4.) There's a Leak

If you pass by your water heater and notice a puddle under it, it may be time to say goodbye. If you can rule out the leak coming from a fitting, pipe, or connection, there's a fracture in your tank that is a clear sign that it's time for a replacement.

If you're experiencing any of these ominous signs (or maybe some others) and are in the process of choosing a new water heater, be sure to take into consideration the size of your house (or business), the number of people living in your home, how much hot water you use on a daily basis, and even maintenance.
