First moves
Water heater leaking in Greeley: four moves while you find the spot
These limit the damage until a plumber can look. They are not the repair.
Close the cold-water valve
It is on the cold pipe into the top of the tank.
Cut the electric power
Electric heater: breaker off. Gas heater: this page gives no instruction for the gas control, so tell the plumber it is gas.
Valve will not close?
Shut off the main water supply. How to shut off the water to your house
Match the spot
Check the component list below and tell the plumber which part is leaking.
Rotten-egg smell near a gas heater? Treat it as gas first.
Leave immediately and move a safe distance. Do not use anything that can spark, such as a light switch. Call 911 once you are clear, then your gas utility.
Water you cannot stop. If the water keeps coming and the valves will not hold it, see emergency plumber for what counts as an emergency.
Where it comes from
Five places a tank leaks, and what each can mean
Review the component checklist below to identify the issue: Which spot it is helps decide between a repair and a new heater, and a plumber confirms it.
- 1
Fittings on top
Water at a pipe connection where the cold and hot lines meet the tank can be a loose or worn fitting. That is a fitting problem, not a failed tank.
- 2
The relief valve and its pipe
Water from the pipe that runs down from the valve means the valve is dripping or discharging. It is the tank's safety device, so this is a plumber question.
- 3
The side or jacket
Water running down or seeping through the outer jacket can mean the tank body is leaking. It can also be moisture on the outside, such as condensation, or water from a pipe above.
- 4
The drain valve
A drip near the bottom can be the drain valve itself, and a valve can be replaced.
- 5
The base or the pan
Water collecting at the base can come from any spot above it, or from the tank. If the tank body is the source, replacement is the question to ask.

A fitting or a valve, or the tank itself
The spot sorts the leak into one of two kinds, and each points to a different page.
A fitting or a valve
- Spots 1, 2 and 4: a top fitting, the relief valve pipe, the drain valve
- The part is replaced or tightened, and the tank stays
The parts and what a repair involves: Water heater repair
The tank body
- Spots 3 and 5, when the water is coming from the tank itself
- A tank body that leaks is a replacement question
What a replacement involves: Water heater replacement
Water from the pipe at the side
A dripping relief valve pipe
The relief valve is the tank's safety device, and the pipe attached to it is where its water goes. Water coming out of that pipe is a plumber question, whether it drips now and then or runs.
This page gives no instruction about the valve or the pipe, and it does not say what the water means for your heater. Note when the water appears and how much, and tell the plumber.
Water in the house
Limiting the damage
Soak up what you can and move belongings out of the wet area. Keep clear of standing water near outlets, the electrical panel or the heater's wiring.
Wet drywall, insulation and flooring can need professional drying, which is separate from the plumbing repair. If you may make an insurance claim, photograph the damage before cleanup.
Tell the plumber
- Which spot the water comes from, by number
- Whether the heater is gas or electric, and roughly how old it is
- Whether the tank's valve closed and the water stopped
- How much water, and when it started
- Any smell, or anything you switched off
