When winter hits in Richmond, the last thing you want is to step into an icy shower or discover your water heater has quit overnight. Unfortunately, cold weather tends to expose weak or aging systems just when you need them most.
If your water heater is on its last leg, it often gives you warning signs before it fails. Here are seven red flags to watch for, and what to do if you notice them.
Why Winter Makes Water Heater Problems Worse
During winter, your water heater works overtime. The incoming water is colder, your home’s demand for hot water rises, and any existing wear and tear becomes more noticeable. Small issues like sediment buildup or corrosion can quickly turn into full-blown leaks or total system failure.
That’s why fall is the perfect time to schedule a professional inspection. At Davis & Green, our licensed plumbers help Richmond homeowners catch small problems early, saving you from cold showers, high energy bills, and costly repairs later.
1. Fluctuating Water Temperatures
If your shower goes from steaming hot to ice cold without warning, your water heater’s thermostat or heating element could be failing. But that’s not the only culprit; sediment buildup at the bottom of the tank can block heat transfer, causing inconsistent performance.
Temperature swings can also occur if your system is undersized for your household’s demand, something many homeowners discover during holiday gatherings or cold snaps.
2. Rusty or Discolored Water
Rust-colored or murky water is one of the most common and serious warning signs of a failing water heater. This discoloration happens when the tank or anode rod begins to corrode from the inside out.
If the rusty tint appears only in hot water, the corrosion is likely inside your tank, meaning a leak or rupture could be next. If both hot and cold water are affected, the problem may lie within your plumbing pipes instead.
You can check by draining a few gallons directly from the water heater. If the water comes out rusty, your tank’s protective lining is likely compromised.
Pro tip: Don’t wait for a rupture. Once corrosion reaches the tank walls, replacement is the only safe solution. Davis & Green can inspect your unit and install a new, energy-efficient model before it fails completely.
3. Strange Noises Coming from the Tank
A healthy water heater runs quietly. If you hear popping, cracking, banging, or rumbling, sediment buildup is usually to blame. Over time, minerals from Richmond’s hard water settle at the bottom of your tank, forming a thick layer that traps water and causes it to “boil” unevenly.
This extra strain forces your system to use more energy and can even cause overheating or premature wear on internal components. In severe cases, sediment buildup can create hot spots that crack the tank’s metal lining.
4. Leaks or Moisture Around the Base
Even a few drops of water near your water heater should raise concern. While some leaks are caused by loose fittings or a faulty pressure relief valve, moisture around the base of the unit often points to internal corrosion or a crack in the tank.
Left unchecked, leaks can cause mold growth, floor damage, or, in extreme cases, flooding. In winter, they can even freeze and expand, worsening the problem.
Pro tip: If you see water pooling, turn off power or gas to the unit and contact Davis & Green right away. Our licensed plumbers can locate the source of the leak and determine whether a repair or full replacement is needed.
5. Reduced Hot Water Supply
If your household runs out of hot water faster than before, it could mean sediment has reduced your tank’s capacity or one of your heating elements has failed.
Another possible cause is a broken dip tube, the component that directs incoming cold water to the bottom of the tank for heating. When it cracks or breaks, cold water mixes with hot, resulting in lukewarm temperatures.
If you’re constantly waiting for your tank to recover, or your showers turn cold halfway through, your unit may be nearing the end of its life.
Pro tip: Davis & Green can assess whether a repair (like replacing a heating element) is possible, or if it’s time to upgrade to a larger or tankless water heater that fits your family’s usage needs.
6. The Age of Your Water Heater
Water heaters don’t last forever. The average lifespan for a traditional tank-style unit is 8 to 12 years, depending on maintenance, water quality, and usage.
Older systems are more prone to corrosion, sediment buildup, and inefficiency. You can find your water heater’s manufacture date on the serial number label. Typically, the first few digits correspond to the year and month of production.
If your system is approaching or past its expected lifespan, replacing it proactively is usually cheaper and safer than waiting for an emergency breakdown.
Pro tip: Davis & Green offers expert water heater replacement services throughout Richmond and Central Virginia. Our team can help you choose between high-efficiency tank models or modern tankless systems for continuous hot water all year long.
7. Rising Energy Bills
If your energy bills are steadily increasing but your usage hasn’t changed, your water heater could be the reason. As internal components wear down or sediment builds up, your system must work harder and longer to heat water, consuming more electricity or gas.
This inefficiency not only drives up monthly costs but can also strain your home’s electrical or gas system, potentially leading to other maintenance issues.
Pro tip: Replacing an older, inefficient water heater with a new ENERGY STAR® model can lower your energy bills by up to 20%. Davis & Green’s technicians can help you select the best size and style for your home and budget.
What to Do If You Notice These Red Flags
-
Shut off power or gas immediately if you see leaking or hear unusual noises.

-
Evaluate repair vs. replacement. Sometimes, simple fixes like replacing an anode rod or heating element will restore function. But if your system is old or corroded, a full replacement may be more cost-effective.

Consider upgrading to a tankless water heater for endless hot water, better efficiency, and a smaller footprint.
