Common Problems & Likely Causes

Symptom Likely Component(s) Typical Repair
No hot water (gas unit) Pilot light, thermocouple, gas control valve Relight pilot, replace thermocouple or gas valve
No hot water (electric unit) Heating element, thermostat, high-limit switch Replace element/thermostat, reset switch
Popping or rumbling noise Sediment buildup on tank floor Drain and flush the tank
Leaking at a fitting or valve Loose connection, worn drain valve, failing T&P valve Tighten or replace the specific part
Leaking from the tank body Internal tank corrosion or failure Not repairable — replacement recommended
Rotten-egg smell in hot water Anode rod reacting with bacteria Flush tank and replace anode rod

Gas vs. Electric Water Heater Repair

Gas Units
Rely on a pilot light, a thermocouple (or thermopile), and a gas control valve. A pilot that repeatedly goes out is one of the most frequent complaints, usually from a worn thermocouple. If you smell gas, don’t attempt to relight the pilot — leave the area and contact your gas utility or 911.
Electric Units
Use one or two heating elements and thermostats. A failed upper element typically causes total loss of hot water; a failed lower element often means a short burst that runs out quickly. Diagnosis includes testing elements, thermostats, and the high-limit reset switch.

When a Water Heater Problem Is a Safety Emergency

If you smell gas near the unit, leave the area, avoid switches or open flame, and contact your gas provider or 911 before contacting a plumber. If the tank is actively flooding a space, shut off the water supply if it’s safe to reach, and shut off power at the breaker for an electric unit rather than working near standing water. If the T&P relief valve is discharging steam or scalding water, keep clear and treat it as an active hazard.

Hard Groundwater Drives Sediment Issues Here

San Tan Valley’s water is delivered through the EPCOR San Tan system, and groundwater across this part of Pinal County is naturally hard. Dissolved minerals settle as sediment at the tank bottom, forcing the unit to work harder and producing the popping or rumbling sounds many homeowners report. Periodic flushing — and in some homes a water softener — slows this down.

What a Plumber Checks During a Repair Visit

1
Fuel type, and whether gas supply or power is reaching the unit
2
Pilot light, thermocouple, or gas control valve condition (gas units)
3
Heating elements, thermostats, and the high-limit switch (electric units)
4
Tank body for signs of rust, corrosion, or active leaking
5
T&P relief valve and drain valve for leaks or failure
6
Sediment level and anode rod condition, when accessible

Repair or Replace?

Factor Favors Repair Favors Replacement
Source of the leak Fitting, valve, or connection The tank body itself
Age of the unit Younger unit, within typical service life Older unit approaching or past typical service life
Repair history First repair issue on the unit Repeated repairs within a short period

Water Heater Repair Process

1
Description of the problem — describe symptoms and whether the unit is gas or electric when you call.
2
On-site diagnosis — a technician inspects the unit and tests the relevant components.
3
Repair recommendation — you’re walked through what’s failed before any work begins.
4
Repair performed — component replacement, sediment flush, valve repair, or ignition service.
5
Function test — the unit is tested to confirm hot water, proper temperature, and no active leaks.

Preventing Future Water Heater Problems

✓Flush the tank periodically to clear sediment, given San Tan Valley’s hard groundwater
✓Have the anode rod inspected and replaced when significantly corroded
✓Test the T&P relief valve periodically to confirm it isn’t stuck or leaking
✓Keep the area around a gas water heater clear of stored items and flammable materials
✓Consider a whole-home water softener if hard water buildup is a recurring issue

Frequently Asked Questions

Why is my water heater not producing hot water?

Usually a failed component — a pilot/thermocouple issue on gas units, or a tripped high-limit switch or failed element on electric units.

Is it worth repairing an old water heater?

A single failed component is often worth repairing regardless of age. A leaking or corroded tank body is not repairable and points to replacement.

Why does my hot water smell strange?

A rotten-egg smell is usually a reaction between the anode rod and bacteria in the water supply, resolved by flushing and replacing the anode rod.

Why is my water heater leaking?

Fitting, drain valve, or T&P valve leaks are usually repairable. A leak from the tank body itself means it has failed and needs replacement.

Does hard water shorten water heater life?

Yes — hard water accelerates sediment buildup, insulating the heating element or burner and adding wear. San Tan Valley’s EPCOR-delivered groundwater is naturally hard.

Should I repair or replace my water heater?

Repair generally makes sense when a specific component failed and the tank is sound. Replacement fits a leaking, corroded, or repeatedly-repaired tank.

What causes popping noises in a water heater?

Sediment settled at the tank bottom creates small steam pockets as the unit heats. A flush typically resolves this if the tank is otherwise sound.

Is a water heater emergency handled after hours?

Yes. 24/7 emergency plumbing is available for an actively leaking or flooding water heater, in addition to standard business hours.
