TL;DR: The seven signs you need a new water heater: age past 10 years, water around the base, rusty hot water, rumbling that flushing no longer fixes, fading hot-water supply, repair quotes over half the new-unit cost, and rising energy bills. Two or more together usually means replace, not repair.
What are the seven warning signs?
1. Age over 10 years. Tank heaters run 8-12 years (industry-typical); in unsoftened Utah County water, the early end. Check the serial-number date on the data plate. 2. Water at the base. A weeping tank seam is corrosion through the vessel, not repairable. 3. Rusty hot-side water. Rust only when running hot water means the tank interior, not the city main. 4. Rumbling and popping. A hardened sediment bed boiling water beneath it, if flushing no longer quiets it, the bed has fused. 5. Shrinking hot showers. Sediment displaces capacity; a 50-gallon tank can behave like a 35. 6. The half-cost rule. A repair quote above 50% of a new unit on an old heater is money into a failing asset. 7. Creeping bills. Scale-insulated elements burn more fuel for the same hot water, water heating is the second-largest home energy use per the U.S. Department of Energy.
Which signs mean act today?
Pooling water, a hissing T&P relief valve, or scorch marks at the burner mean shut off fuel and water and call now, 801-874-8479. Tank failures rarely announce a schedule; they flood a utility room at 3 a.m.
Replace with what?
The honest answer depends on household size, fuel, and budget, covered in tank vs tankless and gas vs electric. Whatever you choose, starting it on softened water is the cheapest longevity upgrade in Utah County. Quotes and same-day swaps: water heater installation or the hub.
