Most homeowners in Northwest Arkansas do not think much about their water heater until the morning they step into a cold shower. By that point, the situation has already become an inconvenience at best and a water damage problem at worst. The good news is that water heaters rarely fail without warning. There are almost always signs that something is off weeks or even months before a full breakdown.
All Calls Plumbing has been serving the Bentonville, Rogers, and Springdale area for 18 years, and water heater service is one of the most common calls we receive. Here is what to watch for in your own home.
Your Hot Water Runs Out Faster Than It Used To
A water heater that used to last through two showers in a row but now struggles to get through one is not just being temperamental. Loss of hot water capacity is often caused by sediment buildup inside the tank. Over time, mineral deposits from hard water settle at the bottom and reduce the unit's ability to heat water efficiently. If you are noticing shorter hot water durations, it is worth having a plumber take a look before the problem gets worse.
You Hear Rumbling or Popping Sounds from the Tank
A quiet water heater is a healthy one. When sediment accumulates and gets repeatedly heated and cooled, it hardens and creates the rumbling or popping sounds that many homeowners describe as coming from their utility room. These sounds are a sign that the heater is working much harder than it should be, which shortens its lifespan and raises your energy bill at the same time.
The Water Looks Rusty or Has an Unusual Smell
Discolored hot water is a red flag. Rust-tinged water coming from your hot water tap often points to corrosion inside the tank, which means the anode rod may need to be replaced or the tank itself is deteriorating from the inside out. A sulfur or rotten egg smell, on the other hand, can indicate bacterial growth inside the tank, which is more common in water heaters that have been set to a low temperature for an extended period of time.
There Is Moisture or Pooling Water Around the Unit
Even a small amount of water pooling around the base of a water heater warrants immediate attention. This can mean a slow leak from a faulty pressure relief valve, a corroded fitting, or a crack in the tank. What starts as a minor drip can turn into a significant water loss situation. If you notice moisture around your unit, do not wait to have it inspected.
The Unit Is More Than 10 to 12 Years Old
Most traditional tank water heaters are designed to last between 8 and 12 years, depending on maintenance and water quality. If your unit is approaching or past that range, it makes sense to start thinking about replacement rather than repair. Proactively replacing a water heater before it fails saves you from the chaos of an emergency and allows you to explore more efficient options, like a tankless system.
Tankless Water Heaters: A Smarter Option for Many NWA Homes
All Calls Plumbing is a certified installer and servicer of Rinnai tankless water heaters. Unlike traditional tank models, tankless systems heat water on demand rather than storing it, which means you never truly run out of hot water, and you are not paying to keep a full tank warm around the clock. They also tend to have a longer operational life than tank units. If you are already facing a water heater replacement, it is worth asking whether a tankless system makes sense for your household.
When to Call a Plumber
Any one of the signs above is worth a phone call. A plumber can tell you a lot about the state of your water heater and help you decide whether a repair or replacement is the right move. We serve homeowners throughout Bentonville, Rogers, Centerton, Cave Springs, Bella Vista, Springdale, and Elm Springs.
