Water Heater Help

Frequently Asked Questions

Use these answers as safe starting points. Equipment-specific gas, electrical, and internal repairs should be handled by a qualified professional.

Why do I have no hot water?

The cause may involve power, a tripped safety, ignition, gas supply, thermostats, heating elements, controls, or the tankless flow system. Avoid opening gas or electrical compartments; note the symptoms and request diagnosis.

What should I do about a leaking tank?

Why is my water heater making strange noises?

Popping or rumbling can be associated with sediment, while ticking, sizzling, or banging may have other causes. If noise is severe, accompanied by leaking, or suggests unsafe operation, stop using the unit and call for service.

Why will the pilot light not stay lit?

A dirty or failed pilot component, gas-control issue, draft condition, or safety shutdown may be involved. Repeated relighting is not a substitute for diagnosis; stop if you smell gas and follow the gas utility’s emergency guidance.

What causes rusty or discolored hot water?

Discoloration can come from the water supply, piping, anode activity, or corrosion in the water heater. Compare hot and cold water carefully, avoid drinking questionable water, and have the source evaluated.

Why does my tankless unit show an error or stop heating?

Record the exact error code and model information if they are easy to access. Flow, scale, sensors, ignition, venting, fuel, or electrical controls may be involved; avoid internal reset or disassembly procedures not intended for homeowners.

Should I repair or replace my water heater?

Repair can make sense for a serviceable component when the tank and overall system are sound. Replacement is worth discussing for a leaking tank, extensive corrosion, recurring failures, unavailable parts, or changing household needs.

What should I do before a technician arrives?

Describe the symptoms, clear a safe path to the unit, secure pets, and gather model information if accessible. Do not remove covers, drain the tank, alter gas piping, or work on energized electrical components.
