Your water heater is one of those appliances you never think about — until it fails. And when it does, it rarely happens at a convenient time. The good news: most water heaters give you warning signs before they completely give out. Knowing what to look for can save you from a flooded utility room, a cold shower, or worse — a burst tank that damages your home.
At SOS Plumbing, we handle water heater replacement throughout Myrtle Beach, Conway, and all of Horry County. Here’s what we tell every homeowner who calls asking whether it’s time to replace.
1. Your Water Heater Is More Than 10 Years Old
Traditional tank water heaters have an average lifespan of 8–12 years. If yours is pushing 10 or beyond, it’s living on borrowed time — even if it seems to be working fine. The internal components, especially the anode rod and tank lining, degrade over time. A proactive replacement saves you from an emergency replacement at the worst possible moment.
2. You’re Getting Rusty or Discolored Hot Water
If the hot water from your taps looks brown, orange, or murky — especially in the morning — that’s a sign of corrosion inside the tank. Once rust sets into the tank lining, it’s only a matter of time before a leak develops. This is not a problem that clears up on its own. If both hot and cold water look discolored, the issue may be in the pipes rather than the heater — call SOS Plumbing and we’ll identify the source.
3. You Hear Rumbling, Popping, or Banging Noises
As water heaters age, sediment — primarily calcium and mineral deposits — accumulates at the bottom of the tank. When the burner fires, water heats through that sediment layer, causing unsettling rumbling and banging sounds. It also forces the unit to work harder, driving up energy bills and accelerating wear. Flushing the tank annually can slow this process, but once heavy sediment buildup is present, replacement is usually the smarter long-term move.
4. You’re Running Out of Hot Water Faster Than You Used To
If your showers are turning cold halfway through, or the dishwasher and washing machine seem to drain your hot water faster than before, your heater’s capacity or heating element may be failing. This can also signal the unit simply can’t keep up with your household’s current demand.
5. You See Moisture, Pooling Water, or Visible Leaks
Any moisture around the base of your water heater is a serious warning sign. Small fractures in the tank can cause slow seeping that turns into a major leak with little notice. Check the fittings first — those can sometimes be tightened. But if the tank itself is weeping, replacement is the only answer. A failed tank can release dozens of gallons and cause significant structural damage.
6. Your Energy Bills Have Been Creeping Up
An aging, inefficient water heater works harder to maintain temperature — and you pay for that extra effort every month. If utility bills have been climbing without an obvious explanation, your water heater could be a major contributor. A new high-efficiency unit, or a switch to tankless, can significantly cut your monthly costs.
