Not every water heater problem means a new water heater. The unit is a collection of components, and often it is one specific component that has failed while everything else is fine. Replacing a tank because of a dead heating element is like replacing your car because of a dead battery. Most homeowners cannot tell the difference between a component failure and a tank that is genuinely at the end of its life. That is where an honest diagnosis matters. We find out what is actually wrong, tell you what it would cost to repair versus a full Water Heater Replacement, and give you a straight recommendation. You make the call. If you're adding hot water to a space that's never had it before, like a finished basement or a garage apartment, that's a different job than a repair. A Water Heater Installation covers what goes into a new setup like that. This page is specifically for diagnosing and fixing a water heater you already have.












Signs You Need a Water Heater Repair
These are the symptoms that bring in most of our repair calls. If you're seeing one of these, it's worth having the unit looked at before it turns into a bigger problem:
- No hot water at all. Could mean a failed heating element, a pilot that's gone out, or a tripped high limit switch. This is the single most common reason people call us.
- Water pooling at the base of the tank. Usually a loose fitting or a failed pressure relief valve, though in some cases it's the tank itself, which is a different conversation.
- Rotten egg or metallic smell in your hot water. Almost always a spent anode rod reacting with bacteria inside the tank, not a sign your water supply is unsafe.
- Popping, rumbling, or banging noises from the tank. Sediment settling at the bottom causes water to boil trapped underneath it. Loud, but rarely an emergency.
- Breaker tripping or a fuse blowing repeatedly. Usually a shorted heating element on electric units. Worth having looked at rather than keep resetting it.
Common Problems We Repair
Different symptoms point to different components. Here is what we look for:
- Heating element failure: Electric water heaters have two. When either one fails, output drops noticeably. This is one of the most common and most repairable problems we see.
- Thermostat issues: Lukewarm water that came on gradually is usually a thermostat, not a tank failure.
- Thermocouple and pilot problems: Gas units that produce less hot water than they used to often have a thermocouple cutting the pilot short, or a burner that needs cleaning.
- Spent anode rod: A rust tint or off smell in your hot water usually means the anode rod inside the tank has been fully consumed. Replacing it protects the tank lining from further corrosion.
- Pressure relief valve: A valve that drips or discharges water is not operating correctly. It is a safety issue that needs to be replaced, not ignored.

We Repair Every Type OF Water Heater
Gas Water Heaters
Gas units usually fail at the pilot assembly, the thermocouple, the gas control valve, or a burner that's collected enough debris to burn unevenly. A pilot that won't stay lit is typically a thermocouple that's stopped sensing correctly, not a failing unit. We test the gas control valve and check for proper draft before recommending anything beyond a component repair.
Electric Water Heaters
Electric units run on two heating elements and two thermostats, and it's common for only one side to fail while the other keeps working, which is why output drops instead of disappearing completely. We test both elements and both thermostats individually to find the actual failure point. A breaker that trips repeatedly and won't reliably reset usually points to a shorted element, a straightforward repair in most cases.
Tankless Water Heaters
Tankless units typically fail from mineral scale restricting flow through the heat exchanger, a clogged inlet filter, or an error code from the unit's control board. Hard water is common enough in this area that scale buildup is one of the most frequent tankless repair calls we get. We flush the heat exchanger, clean the inlet filter, and read the diagnostic code before assuming a part actually needs replacing.
Our Water Heater Repair Process
Talk & Diagnose
We talk through what you've noticed, then inspect the unit directly, testing both heating elements and thermostats on electric units, or checking the pilot assembly, thermocouple, and burner on gas units.
Full Unit Check
We inspect the anode rod and pressure relief valve regardless of what brought us out, so nothing gets missed.
Recommendation and Quote
We give you a clear repair quote and an honest recommendation based on the age and condition of your unit.
Repair or Advice
Most common repairs are completed the same visit. If what we find points to the tank itself, such as corrosion or a failed lining, we tell you that and walk you through replacement options instead.

Water Heater Repair Cost
Repair costs vary by component and how accessible it is. A heating element swap is one of the more straightforward jobs. A thermocouple replacement on a gas unit is typically quick and affordable. An anode rod replacement requires draining part of the tank and takes more time.
We give you the cost before we start, along with our honest take on whether the repair makes sense relative to the age and condition of your unit. If the numbers do not favor repair, we will say so rather than take your money on a fix that only delays the inevitable. Call (517) 742-2848 to talk through what you are seeing.
Why Choose Plumbing by Custom Built
The easy move for a plumber is to recommend replacement whenever a water heater underperforms. We do not default to that. We look at what is actually wrong, compare repair cost to replacement cost, and give you a straight answer based on your specific unit. If repair is the right call, that is what we will tell you.

FAQs
How do I know if my water heater needs repair or replacement in Okemos, MI?
Age and the nature of the problem are the two key factors. A unit under 10 years old with a specific component failure is usually worth repairing. A unit over 12 years old with multiple issues or a corroded tank is typically a better replacement candidate.
What are the most common water heater repairs in Okemos?
Heating element replacement on electric units, thermocouple and pilot assembly issues on gas units, thermostat replacement, anode rod replacement, and pressure relief valve replacement.
Can a water heater be repaired if it is leaking in Okemos, MI?
It depends on where the leak originates. A leak at a fitting, valve, or connection is repairable. A leak from the tank body means the lining has corroded through, and replacement is the only option.
How long does a water heater repair take in Okemos
Most common repairs take one to two hours. We carry the most common replacement parts on the truck so we can usually complete the repair the same visit as the diagnostic.
Is it worth repairing a water heater that's still under warranty?
If the manufacturer's warranty on the tank or a specific part is still active, that changes the math significantly since you may only be covering labor. We check the manufacture date and ask about your warranty documentation before quoting, since it can make repair the clear choice even on an older unit.
