Maybe there are signs you have noticed recently in your hot water supply and is become frustrating for you. This post will help you understand the warning signs of a water heater that is due for replacement and direct you to the best plumbers in NYC for your water heater repairs or replacements.

Water heaters have become very essential for our everyday living especially with tasks like dishwashing and taking a shower. After a period of use, we may begin to notice changes in their efficiency and output then frustration may begin to set in. Imagine taking a shower and the next minute you get hit by a downpour of icy water. Other times, it could be a giant puddle in the basement all thanks to a bad water heater.

Some of the signs that show that you need to replace your water heater are rusty water, rumbling, insufficient hot water, leakage, or an old unit. For a better understanding of how they occur and their effect, read on.

Rusty Water

If you notice rust in your hot water, your water heater is probably rusting from inside and may result in more damage like leaking if not treated. To find out if the rusty water is from your water heater, fill about 3 containers from other outlets, and if it is only your hot water that is colored, you probably need to change your water heater.

Rusting can be prevented by adding aluminum, zinc, or magnesium node to your water heater but if you decide to make use of two rods, ensure that they are of the same metal. This will prevent a chemical reaction between the metals which could lead to more wear.

Noise and Rumbling

After prolonged usage of your water heater, sediments will begin to buildup at the bottom of the tank. The sediments eventually become harder due to further heating and reheating, leading to waste in energy and more usage of your water heater’s capacity. With time, you will begin to hear rumbling and banging noises from your unit, a clear sign of a faulty water heater.

Another issue is that holes and cracks will surface in your water heater as a result of the additional time it will take to heat water. Reach out to plumbing repair experts before it results in leaks or consider changing it completely when you begin to notice these noises.

Insufficient Hot Water

The sediments that have built up over time in your water heater will begin to take up space and separate water from the heat sources which will automatically result in a shortage in the supplied hot water. This is a common sign of a faulty water heater.

Also, if your shower often turns cold before you are done, you should consider changing your water heater.


It is a known fact that metals expand when heated and your water heater’s tank is no exception. This expansion can lead to slight fractures and a resultant leak from your tank. Although, it is also important to check that there are no other leaks from fittings and connections to the tank because your water heater’s inner tank may stop leaking as soon as it cools down.

To avoid mildew, mold, and water damage, you must pay attention to the leaks. And if you stay in NYC, there are experienced plumbers to help you inspect the leakages and replace your water heater.

An Old Unit

A water heater that has lasted for over 10 years is due for replacement; you can verify your water heater’s exact age through the serial number on the sticker at its top. Even though the manufacturer’s stickers may vary, the year is usually denoted by the first two numbers on the sticker.

Conventional type stickers may look like D081187640 showing that it was manufactured in the year 2008 as seen from the first two numbers.

To use your water heater to its life expectancy of roughly 10 years, ensure to flush it every year to get rid of sediments and keep it in good working condition. Doing it on your own may not be a good idea as you can get burned by hot water. There are licensed professional plumbers in NYC like us at Waterhouse NYC Plumbing to get it done for you.
