Signs it can't wait
- A rotten-egg smell on the hot side that clears completely on the cold side.
- Rust-colored streaking down the outside of the tank or across its fittings.
- Popping or rumbling through the heating cycle that was not there last season.
- A damp ring on the floor under the tank that keeps coming back.
Water pooling at the base of a tank is the tank itself talking, and that condition tends to go from a damp ring to an outright failure without much notice in between.
What a pro does in Dover
A water heater call on well water often opens with a smell rather than a temperature. Sulfate-reducing bacteria are common in shallow Delmarva groundwater, and they react with a standard magnesium anode rod to release hydrogen sulfide, which is the rotten-egg odor that turns up on the hot side and nowhere else. Changing the anode alloy addresses that, and it's a separate conversation from a failing tank. Past the odor question, the element or burner, the thermostat and the pressure relief valve all get tested, and sediment depth gets measured, since iron and manganese out of the Columbia aquifer settle far faster than treated town water leaves anything behind. Location counts too. A tank in an unconditioned crawlspace or a utility closet in Bethany takes salt air on its fittings and its flue, and corrosion on the outside of a unit near the ocean can outrun what's happening inside it. Rental demand is the last variable, because a heater sized for one family runs four back-to-back showers on a Saturday changeover in Ocean City and then recovers all week.
Dover's unique plumbing challenges
About 72 nights a year below freezing, when uninsulated crawlspace lines give out
The oldest blocks in town run plumbing decades older than the newer builds toward Delaware
First frost typically lands around November 13

Seasonal timing
The ten-year normals put 72.3 nights a year below freezing at this latitude, enough to split an outside spigot but nothing like enough to reach a buried main. Cold-weather calls almost always trace back to a line crossing unheated space.
Common questions
Sulfur bacteria in the water react with the magnesium anode rod inside the tank and release hydrogen sulfide gas. The giveaway is that it affects the hot side only. Switching the anode to a different alloy usually ends the odor without touching anything else on the unit.
It's the part designed to corrode so the tank does not. Once it is consumed, corrosion moves on to the steel shell and the glass lining, and that is where a repairable unit becomes a replacement. On aggressive well water the rod gets used up years earlier than it would on treated municipal supply, which is why checking it belongs in any diagnosis here.
On the outside, yes. Units in Fenwick, Ocean City or Chincoteague sit in air carrying salt aerosol, and it attacks the jacket, the flue and exposed fittings faster than it would ten miles inland. A tank can be perfectly sound internally while a vent connection has corroded enough to need attention.
Not by itself. Rumbling is water flashing to steam beneath a layer of settled sediment, which points to buildup rather than imminent failure. It is a signal that the unit is working harder than it should, and leaving it alone shortens the tank's life, so it belongs on the list rather than at the top of it.
You already know that plumbing problems don't go away on their own. And waiting just increases the risks to your house. Plumbers see this hesitation all the time. Instead of regretting not calling earlier, just make that 2-minute call now and get your free estimate.
