A leaking water heater does not always mean a dying water heater. Plenty of leaks come from parts that are cheap and quick to replace: a relief valve that no longer seats, a plastic drain valve that has started to weep, a supply connector with a tired gasket, or a corroded fitting at the top of the tank. Some puddles are not leaks at all but condensation, especially on a newly filled tank or a gas unit starting up in muggy weather. The one leak that cannot be repaired is water seeping from the steel tank, usually through the bottom or a seam. For South Lyon, MI homeowners, the difference between those answers is why diagnosis comes first.
A leak call with us starts with evidence, not guesses. The technician dries everything off so fresh water shows where it starts, then checks the relief valve and its discharge line, the drain valve at the base, and every connection on top. On gas models we also inspect the burner compartment, because water there can be normal startup condensation or a sign of a tank that has failed. A relief valve that keeps releasing water triggers a pressure test: static pressure above roughly 80 psi, or a missing expansion tank on a closed system, will make even a new valve drip. The fix follows the findings.
The repair depends on what we found. Valve and fitting leaks are the good news: relief valves, drain valves, dielectric nipples, and flex connectors are stocked on our trucks, and we can often add an expansion tank or pressure-reducing valve the same day if pressure caused the problem. A leak from the tank body is the bad news, because steel that has rusted through cannot be repaired, and we will say so rather than sell a patch. In both cases, we help limit future damage with a properly drained pan, a leak alarm or automatic shutoff, and a quick lesson on your shutoff valve.

How to Tell Something Is Wrong
Most tanks announce trouble weeks or months ahead with rumbling noises, rusty water, or hot showers that keep getting shorter. If any of the following sound familiar, it's worth having the unit checked:
- Dampness in the combustion area of a gas unit
- Water dripping from the relief valve or out of the end of its discharge pipe
- Rust, green corrosion, or white crust on the fittings at the top of the tank
- Water collecting under or beside the heater
- Rusty or discolored hot water paired with dampness at the base
- A water bill that rises without any change in usage
- A musty odor or soft floor around the heater location
- A drain valve at the bottom of the tank that drips even when closed
A Slow Leak Never Stays Slow
Most water heater failures start small: a popping sound from sediment, a damp spot under the drain valve, or a shower that goes lukewarm a few minutes sooner each week. Call South Lyon Water Heater at (947) 227-7625 at the first sign of trouble.

Why This Job Calls for a Pro
Most leak mistakes happen before any tool comes out. Water travels along pipes and the outer jacket before it drips, so the puddle rarely marks the source, and normal condensation on a gas unit or a cold tank can pass for a leak. Guessing leads to replacing the wrong valve or, worse, missing a tank that is about to fail. The safety side matters as well: a relief valve that is discharging is protecting the tank, and plugging it invites a far worse failure. Brittle old fittings can snap under force, and water around a 240-volt electric heater is a real shock hazard.
Our technicians trace leaks methodically and fix the cause, not just the drip. We dry the unit, watch for fresh water, put a gauge on the system whenever the relief valve is involved, and check for thermal expansion problems that make valves weep. We replace valves and fittings with quality parts, swap plastic drain valves for brass, and add an expansion tank or pressure-reducing valve when pressure is the root problem. If the tank has failed, we tell you directly and explain replacement options, including the drain pan and leak protection that can keep the next failure from soaking your floors.
What to Expect From Our Team
Our workflow is simple and thorough, so nothing gets missed between the fuel supply and the relief line. Here's exactly how a typical visit unfolds:
Stop & Protect
We help you close the cold supply and shut off gas or power, then protect nearby flooring and belongings so the damage stops spreading.
Pinpoint the Leak
Every likely source gets checked: T&P valve, drain valve, inlet and outlet fittings, connectors, condensation, and the tank itself. Nothing gets replaced on a guess.
Test the Pressure
Leaks often have a cause behind the cause. Pressure above about 80 psi or a waterlogged expansion tank gets found and corrected.
Lasting Repair
We replace the failed part, refill and purge the tank, restart the heater, and confirm every joint stays dry. A leaking tank gets an honest replacement recommendation instead.
How to Prevent Water Heater Problems
A few preventive steps can help you avoid a cold shower or a wet floor down the road. Here's where to begin:
- Glance at the heater monthly for damp spots, rust, or crust on the fittings
- Replace a depleted anode rod before the steel tank becomes the next target for corrosion
- A properly drained pan under the tank catches small leaks before they reach your floors
- Make sure a closed plumbing system has a working expansion tank to absorb heated water
- Add a floor sensor or an automatic shutoff valve that closes the supply when it detects water
- Have household pressure measured, since high pressure wears out relief valves and fittings faster
- Draining sediment every year helps the bottom of the tank last longer
DIY vs. Professional Water Heater Leak Repair
Relighting a pilot by following the label is one thing. Diagnosing a gas valve, a burned-out element, a dirty flame sensor, or a tankless error code calls for meters and know-how that a pro brings. Here's how the two approaches stack up:
| Consideration | DIY Attempt | Hiring a Pro |
|---|---|---|
| Finding the Source | Guess based on where water collects | Surfaces dried and each source confirmed |
| T&P Valve | Valve capped to stop the drip, a serious hazard | Valve and pressure both addressed |
| Old Fittings | Tightened until the fitting cracks | Corroded connections replaced with new fittings |
| False Alarms | Unneeded parts or a whole new heater | False leaks ruled out with testing |
| Protecting the Home | No pan, no alarm, no plan | Shutoff labeled and leak alarms suggested |
| Result | Drip returns in weeks | Lasting fix, verified under pressure |
