A puddle beneath a water heater does not identify the source: water can travel down from a connection, valve, or another nearby component. Keep clear of electrical hazards and get the leak assessed promptly. Never cap a relief pipe or assume a leaking tank can be patched.
Where the water ends up is not always where it starts.
Water visible at the base could have run down from above. The inspection needs to distinguish a plumbing connection or valve leak from a damaged storage tank, and from water produced by nearby equipment. Tell the plumber where you first saw moisture rather than diagnosing the tank from the puddle alone.
Rheem recommends prompt professional attention for a leaking water heater. If there are also temperature changes, noises, or an error message, include those symptoms in the same request.

Protect people before protecting belongings.
- Keep children and pets away from the wet area.
- Do not enter standing water near electrical equipment or touch wet controls.
- If you know the correct water shutoff and can reach it safely from a dry location, close it gently; do not force a stuck valve.
- Ask for model-specific guidance on stopping the heater’s energy supply. Do not work on gas piping, electrical wiring, or unfamiliar controls.
- Move belongings only if you can do so without approaching a hazard.
Closing the incoming water does not empty the heater or establish that it is safe to work on. Tell the service team what was shut off. If you suspect a gas leak, leave without operating switches and call emergency services and your gas utility from outside.
Never plug a dripping relief discharge pipe.
The temperature-and-pressure relief system is a protective device. A discharge requires investigation, not a cap, plug, or valve added to stop the water. Do not test or disassemble an unfamiliar relief valve during a leak; discharged water can be very hot.
A professional should determine whether the concern involves the valve, pressure, thermal expansion, temperature control, or another condition. A drain pan can help manage some water but does not repair the leak.
Prepare a useful leak description.
From a safe distance, note whether water is dripping from a visible fitting, running down the jacket, coming from a separate discharge pipe, or simply collecting underneath. Avoid touching pipes to check temperature. A photo of the overall area is often more useful than a close-up that hides the surrounding connections.
Include whether the leak is continuous or appears during heating, whether hot water still works, and whether you recently noticed banging water pipes. For hidden usage elsewhere, see how to investigate a higher water bill.
Compare the actual repair and replacement scopes.
Ask exactly where the leak originates and what evidence supports replacement if it is proposed. A connection repair and a leaking tank are different findings. Discuss access, pan and drainage arrangements, required installation corrections, removal, and written warranty coverage before choosing equipment.
