How long does a water heater last in Detroit?

Plan on 8 to 12 years for a tank and 15 to 20 for a tankless unit. Detroit's moderately hard water pushes a tank toward the low end if nobody flushes it, since sediment overheats the bottom and stresses the steel. An annual flush can extend most tanks to about 12 years. The serial number on the label usually encodes the manufacture year.

Should you drink or cook with water from your hot tap in Detroit?

No. The Detroit Water and Sewerage Department advises using only cold water for drinking and cooking, because lead dissolves more easily into hot water. Homes built before 1945 are the most likely to have a lead service line, and the city estimated about 75,000 were still in service in 2025. If you have one, DWSD recommends running the cold tap for at least five minutes after it sits for several hours and using a filter certified to NSF/ANSI Standard 53.

How do you schedule water heater repair in Detroit?

Call Mr. Rooter Plumbing of Detroit or request a service appointment online and tell us what you're seeing: no hot water, a leak, strange noises, or a pilot light going out. We'll book the first open appointment, and your plumber will diagnose the heater and walk you through repair and replacement options before touching a tool.

What should you do if your water heater starts leaking?

First, shut the cold-water valve on top of the tank. Then turn the gas control to off, or flip the breaker on an electric unit. Many older Detroit basements have a nearby floor drain, so if the leak is steady, run a garden hose from the tank's drain valve to it. A dripping relief valve frequently indicates high pressure, not a failed tank, so call us before you assume the worst.

How Our Detroit Plumbers Diagnose and Repair Water Heaters

Sediment, usually. Detroit's tap water averages about 107 parts per million of hardness, and each heat cycle drops calcium and magnesium onto the tank floor. That crust insulates the water from the burner, slowing recovery and causing the tank to pop or rumble. On electric units, a burned-out lower element causes the same short showers. We flush the tank and test both elements with a meter.
A worn thermocouple or clogged pilot tube usually causes this. Older Detroit houses add a twist. Many gas water heaters share a masonry chimney with the furnace, and when someone swaps the furnace for a high-efficiency model, the water heater is left standing in a flue which was designed for two appliances. You end up with a weak draft, which lets exhaust back up into the basement (a CO hazard). We check the draft and test for CO prior to relighting anything.
Repair wins on a tank under about eight years old with a failed thermostat, element, gas valve, or relief valve. A leaking tank is different. Once the steel liner has rusted through, you can't do anything about it. Winter makes a difference too, as Detroit tap water can drop to about 34°F in the coldest months, so a tired heater will struggle when you need it most. We put both options in writing so you can make your own decision.

About Our Water Heater Repair and Replacement Services in Detroit

Most repairs we handle involve the thermostat, gas control valve, heating element, anode rod, or temperature and pressure relief valve, but the anode rod is often the cause of your water heater issue. An anode rod is a magnesium or aluminum rod that corrodes in place of your steel tank, and once it's eaten down to the core wire, rust starts inside the tank. Checking it every two to three years, more often on softened water, buys the tank real time.

When a tank has failed, our water heater installation crew sizes the new unit to your household's peak demand instead of copying the old label. In century-old homes around Boston-Edison and Indian Village, the job often means relining or rerouting the vent and adding a thermal expansion tank where the system needs one. Replacement in Detroit calls for a permit through BSEED. We pull it and schedule the inspection.

Tight basement space or a big family sharing one tank points to tankless water heaters, which heat on demand and last longer than most tanks. At Detroit's hardness level, a tankless heat exchanger needs a descaling flush about once a year, and a softener protects it between visits. If yours has stopped regenerating, our team handles water softener repair too.
