Signs Your Water Heater Needs a Replacement Soon

Tank-type water heaters typically last between seven and ten years. However, they can show signs of aging and deterioration before that, especially if they don’t get regularly serviced. Because the water heater is among the most used plumbing-related appliances in your home, it’s also the one that gets battered the most.

If you do not know the signs that your hot water heater has problems, you can find yourself in the middle of an ice-cold shower. You don’t want that to happen, of course. So, what are the telltale signs that your hot water heater is about to go out? Read on and find out about the signs you should look out for, as shared by Candu Plumbing & Rooter, trusted professional plumber in Canoga Park: 

The Tank Is Not Producing Enough Hot Water

When tank-type water heaters are not properly maintained, the hard water can lead to mineral sediment formation. When this builds up, it takes space and leaves less room for water. Eventually, this can reduce the amount of hot water available. Gas heaters and the electric heating parts need to work harder, too, to reach the temperature on the thermostat. That means the water heater continuously works but can’t keep up. This is especially problematic if you have multiple bathrooms in your home and your family members tend to shower around the same time. 

The Tank Is Quite Old 

As much as you want to use your appliances forever, you can’t because they are used regularly and get worn and torn. Typically, water heaters last for around ten years before requiring replacement. However, you can use yours for longer than that if you maintain your unit regularly. If you don’t know how old your water heater is, you can check the serial number found on the label attached to the heater’s upper part. The first two digits indicate the last two numbers of the year it was manufactured. 

You Get Cloudy or Rusty Water

Another warning sign is that the water that you’re getting at home is somewhat cloudy. There may also be noticeable rust deposits and a metallic odor that comes with the hot water. This could indicate rusty pipes or the occurrence of rust in the water heater. Cloudy water is also indicative of mineral deposits in the water heater.


The most apparent sign of a problem with water heaters is a leak. IF there’s water dripping from any part of the water heater or if there’s water pooling around the unit, it’s time to call in the pros. The problem may still be resolved, but it could also be an indication that your water heater is nearing its end. 

Banging Noises

If you hear noises from the water heater that haven’t been there before, it’s a sign that there’s something wrong with the system. There may be too much mineral sediment drifting around the tank, causing the banging or thumping sound. 


If you see any of these signs, it means you need to call a professional plumber immediately. There may be instances where a repair works, and you can still extend the life of your water heater. However, if more than one of these signs manifest, it’s probably a clue that you need to get a new system because yours will fail sooner rather than later. Of course, you don’t want that to happen when you need hot water the most. It’s best to be proactive when it comes to the replacement of your water heater.
