Signs You Need To Replace Your Old Water Heater
Sometimes, when your water heater stops working, a few simple repairs are enough to get it back up and running. However, other times, it might be best to replace your water heater altogether. If you think there might be something wrong with your unit, you don’t want to wait until it’s a plumbing emergency — like a burst water heater tank.
Call Universe Home Services at the first sign of trouble. We’ll be there promptly and can help you determine if you need water heater repairs or if you should replace your water heater.
Common Signs You Should Replace Your Old Water Heater:
- The water heater is 10 to 12 years or older.
- It needs frequent, recurring repairs.
- You notice reduced efficiency/not enough hot water.
- It makes loud, unusual banging or rumbling noises.
- There’s a leak or suspected leak in the tank.
Other issues, such as a lack of hot water, sediment buildup, or rust-colored hot water from your taps could be signs of a relatively minor issue. It’s best to have a professional look at it to determine if repairs will be enough. We offer free estimates for water heater installations.

How Often Should You Flush A Water Heater?
To avoid an unexpected leak or repair need, we recommend routine water heater maintenance. Flushing out your water heater is an important step in any water heater maintenance. Over time, water heaters build up sediment, calcium, and minerals in the bottom of the tank. These can keep the unit from properly heating the water and cause leaking from the base of the tank.
Most water heater manufacturers and plumbers recommend flushing a water heater once a year. This will prevent sediment buildup and avoid all the potential problems that come with it.
