Family Handyman reported that a 21-year-old water heater rusted through and flooded much of a Minnesota homeowner’s utility-room floor. The homeowner shut off the main water after discovering the heater’s supply valve would not close, but plumbers said he should also have shut off the heater’s gas or electricity before handling it.
Family Handyman reported that a 21-year-old water heater rusted through and flooded much of the floor in a Minnesota homeowner’s utility area. The homeowner, identified as Ethan, stopped the water only after finding that the heater’s supply valve would not close; plumbers consulted by the publication said he also should have shut off the heater’s gas or electricity before working on it.
Ethan discovered the problem after filling a bathtub for his young daughter and finding that the water was not hot. When he opened the utility closet, he found a puddle covering most of the floor. He recognized that the tank had rusted out and that replacement was needed, according to the account.
He first closed the heater’s supply valve and attached a hose to the tank’s drain spigot. When water was still flowing after he returned from a trip to a home improvement store, he realized the valve was not shutting off the supply. He then shut off the home’s main water. The next morning, he installed a replacement heater and got help from his father-in-law to carry the old unit upstairs. Ethan said the old heater weighed more than 120 pounds and leaked during removal.
The report says the homeowner’s heater was well beyond the typical 10-to-15-year lifespan cited by its experts for gas and propane models. It does not identify the heater’s fuel type. Plumbers said a failed valve on an older heater can result from deteriorated gaskets or buildup. The publication’s experts considered shutting off the main supply the right response once Ethan found the local valve was faulty.
A Leak Can Outrun a Slow Shutoff
A failed tank can release water into a home, and a faulty valve can complicate efforts to stop it. Plumber Brendan Tonks told Family Handyman that delaying the main shutoff could mean hundreds of gallons on the floor. The report does not give a measured amount of water from Ethan’s leak or a documented repair bill, so the scale of damage beyond the wet floor is unknown.
The publication lists possible replacement costs of about $700 for a DIY installation and $1,500 to $3,500 for professional work. Those are estimates in its report, not costs confirmed for Ethan’s home. It also says water damage and mold remediation can cost thousands to tens of thousands of dollars if a leak is not caught promptly. The figures show why early leak detection and working shutoff valves can matter to household budgets.
Experts also identified a safety step that Ethan missed: turning off the heater’s gas or electricity before handling it. Because water heaters involve fuel or electrical connections, the plumbers cautioned that replacement can pose hazards. Homeowners who lack relevant experience should use a licensed professional and follow applicable safety and permit requirements.
An Aging Tank and Two Valves
Ethan lives in a 1940s bungalow in Minnesota, according to Family Handyman. The publication’s experts said cold climates can make water heaters work harder, but the supplied report does not establish that the climate caused this particular tank to fail. They pointed instead to its age and corrosion as unsurprising factors: the tank was 21 years old, compared with the 10-to-15-year lifespan they cited for gas and propane heaters.
The incident involved two separate shutoffs. The heater’s supply valve did not stop water from reaching the tank, so Ethan used the home’s main shutoff. Plumber Kolby Barnes noted that older houses such as Ethan’s may have gate valves, which can also be vulnerable to buildup and may fail to close. The report does not say whether Ethan’s main valve had that problem.
Family Handyman’s experts said replacing an internal anode rod every few years can help limit corrosion. The publication gave a typical cost of $20 to $50 for a DIY replacement or $150 to $600 for professional service. Those estimates are general guidance from the report; it does not say whether Ethan’s anode rod had been replaced or whether that would have prevented this failure.
““If there’s a silver lining here, it’s that we were home when this happened.””

Damage and Repair Costs Unreported
The supplied account does not state how much water escaped, whether the basement sustained lasting damage, or whether mold remediation was needed. It also gives no itemized bill for Ethan’s replacement, no model or fuel type for the old heater, and no details about the replacement unit or any permits or inspections.
The experts discussed cold-weather demands and aging components as relevant considerations, but the report does not identify a single confirmed cause beyond the tank having rusted out. It does not establish whether maintenance could have extended this specific heater’s life or prevented the leak. No information is provided about an insurance claim or the condition of the home’s main shutoff valve.
Check Shutoffs Before a Failure
The report does not describe a scheduled follow-up or further work at Ethan’s home. For other homeowners, the steps raised by its experts are to know where the main water shutoff is, have aging equipment inspected, and consider leak sensors with automatic shutoff. A plumber can assess whether a heater, supply valve or main shutoff needs replacement and explain local permit requirements.
If a water heater is leaking, the account’s experts advise stopping the water supply and shutting off the unit’s gas or electricity before touching it. Water, electrical components and fuel connections can create serious hazards. Anyone uncertain how to isolate the system safely should keep clear and contact a licensed plumber or other qualified professional. The report does not provide a complete procedure for every heater type or home setup.
Key Questions
What happened to Ethan’s water heater?
Family Handyman reported that the 21-year-old tank rusted through, leaving a puddle across much of the utility-area floor. Ethan discovered the leak after the hot water stopped working.
Why did Ethan shut off the home’s main water?
The heater’s supply valve did not stop the water flow. After seeing that water continued draining from the tank, he shut off the main water supply to the house.
What safety step did plumbers say he missed?
The experts said he should have shut off the heater’s gas or electricity before handling it. They warned that fuel and electrical components can be dangerous; uncertain homeowners should call a licensed professional.
How long do water heaters typically last?
The plumbers consulted by Family Handyman said gas and propane water heaters typically last 10 to 15 years before corrosion. The report does not give a typical lifespan for every heater type.
Could a leak sensor have helped?
Plumber Kolby Barnes said homeowners could consider smart leak-monitoring devices that can shut off water in an emergency. The report does not say whether Ethan had one or whether a particular device would have stopped this leak.
