Most water heaters do not simply wear out; they rust out or scale up, and both problems can be held off for years. As water heats, dissolved minerals drop out of solution and settle into a layer of sediment on the tank floor. On a gas unit, that layer sits between the flame and the water, so the steel runs hotter and the tank starts to rumble and pop. On an electric unit, it builds up around the lower element until the element burns out. Meanwhile the anode rod, a metal rod designed to corrode so the tank does not, dissolves a little every month. Once it is gone, the tank itself becomes the target. In Rochester, MN, we see this pattern constantly, and most of it was preventable.
Here is what the visit covers. We drain the tank and flush out sediment until the water runs clean. We pull the anode rod to see how much protection remains and replace it when needed. We lift the T&P valve lever to confirm it opens, then watch it reseat without dripping. For gas equipment, we inspect the burner and flame, pilot or ignition parts, thermocouple or flame sensor, and the vent and draft. For electric equipment, we meter the elements and check the thermostats and wiring. Then we check the expansion tank's pressure, confirm a safe temperature setting near 120 degrees, and look over every fitting for early signs of a leak.
Tankless water heaters have their own maintenance needs. Scale builds up inside the heat exchanger, especially in hard water, and eventually triggers flow problems, fluctuating temperatures, and error codes. We descale the heat exchanger with a pump and descaling solution through the service valves, clean the inlet filter, check the venting and condensate line on condensing models, and review the unit's error history. At the end of any visit, you get a plain-language report of what we found. Call (507) 243-0428 to schedule water heater maintenance in Rochester before a small issue turns into a leak.

Symptoms That Mean It's Time to Call
Water heaters usually give plenty of warning before they fail, as long as you know what to look and listen for. If any of the following sound familiar, it's worth having the unit checked:
- Higher gas or electric costs for the same routine
- Shorter showers before the water turns lukewarm
- A tankless unit showing error codes or fluctuating temperatures
- Rumbling, popping, or crackling from the tank as it heats
- Hot water that looks cloudy or rust-colored
- A rotten-egg smell from the hot water
- Small drips at the drain valve or connections
- More than a year since anyone flushed the tank
A Slow Leak Never Stays Slow
A little rust-colored water or a relief valve that drips now and then can be the first hint of a tank that is close to the end. If you notice any of these signs, contact Rochester Water Heater at (507) 243-0428 for a prompt inspection.

What a Trained Technician Brings to the Job
The homeowner's side of maintenance is short: keep the area clear, watch for drips, and pay attention to new sounds. The rest carries more risk than it looks. Flushing involves scalding water and an old plastic drain valve that may crack or refuse to seal. Anode rods are often seized in place and need significant force, sometimes with a flexible rod for low-clearance spaces. An older T&P valve may not reseat once tested, which leaves you with a drip and a replacement to arrange. And on gas heaters, the burner and vent affect how combustion gases leave the house, which is not something to guess about.
We come ready for the common surprises: a drain valve that will not reseal, an anode rod that has turned to wire, a relief valve that drips after testing. We carry replacements, along with meters for element and thermostat testing and a descaling kit for tankless units. More than parts, we bring experience. Small signs, like rust at a connection, a weak flame, or a waterlogged expansion tank, point to future problems, and catching them early is the entire point of the visit. That is how a routine visit adds years to a heater's life.
How We Handle Water Heater Maintenance
Our workflow is simple and thorough, so nothing gets missed between the fuel supply and the relief line. Here's the short version:
Initial Inspection
We check for leaks, test the T&P relief valve, verify the temperature setting, and inspect the burner and vent on gas units or the elements on electric ones.
Drain and Flush
We drain the tank and flush it until the water runs clear, clearing the sediment that causes rumbling and robs efficiency.
Component Inspection
Anode condition tells us how well the tank is protected, and the expansion tank check confirms thermal expansion is being absorbed.
Settings and Report
We set the thermostat near 120 degrees for safety and efficiency, refill and test the unit, and give you a clear report of what we found.

Most of the failures we see could have been delayed for years with basic upkeep. Follow these tips from our technicians:
- Make an annual flush part of your home maintenance routine
- Descale tankless units once a year, or more often in hard water
- Keep the thermostat near 120 degrees to limit scalding and slow sediment buildup
- Have the anode rod checked every few years and replaced when it is mostly gone
- Consider a water softener if hard water keeps building sediment and scale
- Check the drain pan and fittings every few months for drips or rust
- Keep at least a couple of feet clear around the heater for air and service access
Should You DIY or Call a Pro?
Some simple checks are fine to do yourself, but most water heater repairs benefit from professional tools, training, and experience. Here's a comparison:
| Consideration | DIY Attempt | Professional Service |
|---|---|---|
| Flushing | Sediment clogs the valve midway | Valve checked and replaced if needed |
| Anode Rod | Seized fitting and limited clearance | Pulled, inspected, and replaced when consumed |
| T&P Testing | Older valve may drip after testing | Proper discharge line confirmed |
| Gas Components | Carbon monoxide risk if venting is off | Burner, pilot, and draft checked |
| Tankless Care | Missing pump or isolation valves | Error history reviewed |
| System Pressure | Air charge never checked | Failing tank flagged |
