Inspection, Diagnostic, & Repair Guide to Gas-Fueled Hot Water Heaters
How do we Identify a Natural Gas or LP Gas-fired Water Heater?
It's easy to identify a gas-fired water heater and to spot its parts and piping and controls:
if you can find your water heater tank at all, take a look at what pipes and wires are connected to it.
A gas-fired water heater will have two water pipes connected to it (cold-in and hot out), and a pipe or in some jurisdictions a flexible copper tube bringing LP gas or natural gas to the heater.
The gas fired water heater will have a flue or "chimney" which vents combustion gases outside, either by connection to an existing chimney or flue, or in the case of power-vented and high efficiency gas water heaters, flue gases may be vented outdoors by a plastic pipe.
You'll also see a thermostat and gas valve control which combines a temperature setting with a safety device that senses the presence of a gas flame. (If there is no flame the control will turn off the flow of gas to the appliance.)
Lots of newer gas fired water heaters will also include a flue gas spill switch at the draft hood atop the water heater.
Caution: sometimes an electric or other additional water heater is installed as an additional or backup hot water source, so you'll also want to see if you have other hot water heating equipment installed besides the first water heater that you see.
Other hot water sources, such as a TANKLESS COIL for making domestic hot water may also be present.

Gas Water Heater Inspection Points
...
Gas Water Heater Flame Defects
Check for flame color indicating inadequate combustion air, damaged gas burners, gas flame roll-out burn marks, dirty or obstructed gas burner orifices, uneven flames.
See GAS FLAME & NOISE DEFECTS for details
...
Inadequate Combustion Air at Gas Water Heaters
Check for proper combustion air supply for your gas fired water heater.
Failure to provide sufficient combustion air is dangerous: lack of adequate combustion air will cause a gas burner to produce dangerous, potentially fatal carbon monoxide gas.
...
Gas Water Heater Relief Valve Hazards
Check the pressure and temperature relief valve on your water heater: look for evidence of corrosion, leaks, improper installation, etc. A missing, modified, blocked, or leaky pressure relief valve is extremely dangerous and can lead to a catastrophic
BLEVE boiling liquid vapor explosion
that can cause severe damage or even fatalities at a building.
See details also at RELIEF VALVES - TP VALVES
...
Gas Water Heater Installation Location, Position, Mechanical Damage
Look for evidence of leaks in the hot water tank, or mechanical damage, or improper installation.
For example most water heaters are intended to be installed in a vertical position. Installing a hot water tank horizontally or in a hole in a crawl space is likely to cause early failure of the heater, violate the manufacturer's guidelines, and may be dangerous.
...
Leaky water heater tanks & other leaks
In our photo at above left a gas-fired water heater is leaking.
That puddle on the floor needs investigation. Look for leaks at valves and piping around the water heater, leaks in the water heater tank itself, and look for leaks at the pressure/temperature relief valve.
...
Check the settings of the Gas Water Heater Control Temperature settings
Watch out: Water heater temperatures set above 120F risk scalding the building occupants unless a mixing valve or anti-scald valve system has been installed.
See details at GAS HOT WATER TEMPERATURE CONTROL - instructions for setting the temperature control on gas fired water heaters
For a water heater temperature set too low, providing water that is not hot enough.
see WATER HEATER TEMPERATURE TOO LOW.
On a gas fired water heater the heater temperature control is usually on the gas valve itself - the black dial shown in the photo above..
See ANTI_SCALD VALVES & HOT WATER QUANTITY for details about safe hot water temperatures.
...
Check Gas Water Heater Piping, Valves, Controls
Check the water piping and control valves connected to the water heater for leaks, support, and for proper location of shutoff valves. An improperly installed shutoff valve on a water heater can be very dangerous, risking an explosion.
Usually the "hot water tank shutoff valve" is installed only on the cold water pipe coming into the water tank (blue arrow in our photo at left)..
There should be no shutoff valve installed on the hot water line (red arrow in our photo) leaving the water tank.
Check for Gas Leaks: In addition to a characteristic odor that you may smell associated with LP or natural gas leaks, a prolonged gas leak may leave telltale dark stains on the gas piping or control.
See GAS LEAK DETECTION, LP / NG for details.
Vacuum relief valves are required at water heaters in some communities, to protect against collapse of the water storage tank and to prevent backup of hot water into the cold water piping should cold water pressure drop.
See this Carson Dunlop sketch of a vacuum relief valve [image].
Plastic piping used for hot water distribution & connected to a water heater
In our photo above a gas-fired water heater is connected to plastic water supply piping. The pressure rating of plastic water piping systems is usually specified in terms of the temperature as well as pressure in the piping system.
Watch out: hot water temperatures may reduce the permitted pressure rating of plastic water piping in some installations, depending on the brand and product type of plastic water piping installed.
The risk is a burst water pipe, scalding, or flooding in the building.
On some plastic water piping systems you may also find a hot water expansion relief valve installed to provide added protection to the system.
An expansion tank or additional pressure/temperature relief valves can prevent these problems and may also extend the life of the water heater. Details are
at HOT WATER EXPANSION TANKS
and at HOT WATER EXPANSION VALVES
If plastic water piping is installed, such as polybutylene water supply piping, it should be at least 18" from the water heater itself.
Corrosion & leaks at water heater piping & connections
Our photo above shows corrosion at dissimilar metals at the top of a water heater tank. When the connections at the water heater top are sufficiently rusted and corroded the heater will be un-repairable.
...
Check Gas Water Heater Insulation
Look for insulation that has been improperly added to the water heater tank - it may be unsafe and may violate the manufacturer's installation instructions and warranty.
...
Antiquated & Antique Gas Fired Water Heaters
Just below we show a still-working Standard Combination Gas FIred Boiler / Water Heater manufactured by Keystone Supply in Philadelphia, PA. I think this water heater is more than 80 years old.
The antique wall-mounted gas-fired water heater shown below is installed in the Gaudi Apartments in Barcelona, Spain.
By modern standards this is an unsafe water heater, venting directly to the indoor space. I suspect that originally it vented outdoors.
...
Check the Sacrificial Anode & Dip Tube of the Water Heater Tank
The dip tube on many water heaters functions as a sacrificial anode, as we show here.
By constructing the dip tube of a metal which is more readily corroded than the steel of a steel hot water tank, the anode protects the hot water tank from early failure due to corrosion.
Here Carson Dunlop Associates' sketch shows the location of the sacrificial anode on an electric water heater.
If your water supply happens to be highly conductive or corrosive
see WATER TESTING GUIDE for details
then the dip tub/sacrificial anode in the water tank may indeed corrode away until it leaks (dropping the hot water temperature) or disappears entirely.
If your hot water smells like rotten eggs,
you should definitely check the condition of the sacrificial anode on the hot water heater, no matter what kind of water tank you've got installed.
For details of how to inspect or replace the sacrificial anode or dip-tube on a water heater, please
see WATER HEATER ANODES & DIP TUBES
...

of GAS FIRED WATER HEATERS VENTING & COMBUSTION AIR HAZARDS
Our photo above shows an LP gas fired water heater that caught fire.
This outdoor water heater installation was observed at the Ex Hacienda, Gogorron, San Luis Potosi, Mexico.
The complete absence of a venting chimney on this heater may have been a factor in its poor operation.
The water heater inspection dog was a volunteer.
Check for proper exhaust venting of combustion products from your gas fired water heater (calorifier, geyser, hot water cylinder).

Restore frozen hot water system in zero degree weather
0° weather cold water is working and running fine and flowing fine. Hot water line in all faucets tub in bathroom bathroom sinks kitchen sinks the hot water line is not flowing at all. I have a gas water heater and the gas is on. - On 2021-02-17 by Yvette
Reply by (mod) -
So the frozen point is somewhere in the common cold-in to the water heater or in the hot-out from the water heater before it branches off to all of those various locations.
Take a look at the suggestions at PIPE FREEZE-UP POINTS https://inspectapedia.com/plumbing/Pipe_Freeze_Points.php
and then grab a hair dryer and see if you can thaw the freeze-point; when you find it you'll know where you need to add a heat source and fix cold drafts so as to avoid having the problem over and over.
Drained water had so much crud I replaced it
I drained a water heater at my mothers house that was over 30 years old and had never been cleaned. it was over 1/3 of the way full of black goop. The sediment had built up so much i ended up replacing the Unit. Proper Maintenance would have prevented this. On 2021-01-06 - by Justin Heck
Leaks at new water heater: what to do?
new water heater leaking from the bottom - On 2020-06-10 by Willie Roberts
Reply by (mod) -
Willie
Let's start by inspecting every Plumbing connection above or near the top of the water heater and also the temperature pressure relief valve connection on the side of the water heater.
If any of those is leaking water could be running down inside the jacket of the water heater and out at the bottom. If you are absolutely confident that there are no plumbing leaks into the heater body or insulation jacket that it sounds to me as if the unit is defective and needs to be replaced under warranty
