Question about Water Heaters

1 Answer

Is this a dangerous gas leak?

My hotwater heater is in the laundry. There is a measureable leak 2.9% LEL on one of the tabs on the appliance regulator/control valve. I had it replaced under warrantee. Same problem still. The repair guy said stuff like, I don't think it is dangerous, but if you are unhappy... It is in an enclosed space - no window to open - on the lowest level of the house. How do I tell the difference between an OK gas smell and a NOT OK (dangerous) gas smell?

SOURCE: pilot light going out on whirlpool hotwater heater-Fgif403t Flam

This is not a solution to that problem, but the dripping water is just condensation from the cold water in the tank. Like a coke can on a warm day. It goes away after everything warms up. It is more than likely a gas valve, but I have fooled mine into working by not turning the valve all the way up to the full on position.

SOURCE: gas smell during startup of GE hot water heater

yes, provided there is no excessive build up. The gas and air mix must be right before the mixture will ignit. a household stove will do this each time it's turned on. That's why yhe igniter sparkk hits about three times before it lights. proper venting will confine any fumes to the cimbustion chamber to be carried out the exhaust. If the odor is strong then have the appliance checked for safety sake.

SOURCE: I have a GG40T06/487-246 GE SmartWater Water

A 10 year old water heater is at the end of its life expectancy. No sense replacing a gas valve to have the tank rust out next month. I'ld replace the whole unit. Also, install a drip pan, under it and a WAGS safety device. Any water in the pan and the WAGS will shut off he Water and Gas. If your water heater has an expansion tank near by, replace that too.

On A.O. Smith water heater model BTH 199 100 where is the heat sensor rod located ?


Parts list:
http://www.hotwater.com/lit/partslists/197728-004.pdf
Flame rod, flame sensor sits next to igniter inside combustion chamber. This can be cleaned with sandpaper. Do not touch with fingers. Purpose of flame rod is to detect whether ignition has caused actual, sustainable fire inside the combustion chamber.
If sensor is bad, or no ignition is detected after 2-3 attempts, then 'no ignition' error is given.
Bad gas control valve, bad-or-dirty flame rod-sensor, low gas pressure, misaligned rod, dirty combustion parts, etc

Gas exhaust smell when Hot water heater ignites


Absolute danger here:

1) Call gas company IMMEDIATELY to check for gas leak that can cause explosion and fire.

2) Call plumber immediately to fix improper combustion or improper vent before toxic combustion by-product kills family.
Gas appliances must vent toxic by-product outside and away from home where the gasses will kill the planet instead of you.

A strong smell of gas when first comeson


Absolute danger>>>>!!!!!!!
You absolutely must call gas company immediately.
They will turn off gas to water heater immediately.
Leaking gas appliance is extremely dangerous.

If you have propane, the gas is heavier than air and will settle to floor. So you can be standing in an invisible puddle of explosive gas and never smell it.
If you have natural gas, the gas rises to ceiling. The entire ceiling cavity can be filled with explosive gas, but you only smelled it briefly before it drifted upwards.

Do not delay getting this problem repaired by professionals, or fixya might lose a customer.

Maybe I am not understanding your problem exactly, but if you have the instant hotwater system installed it should be measuring the temperature of the water in the hot water line and if it drops below the set level it should open the hot water side until the temperature is reached. If it was installed correctly it puts the hot water back into the cold water line so it isn't wasted.

My heater control valve has a small leak it looks like water is dripping from it


Not enough information to fully answer question.

Control valve is usually associated with the gas line and gas control valve.
There should not be water dripping from control valve.
Open following link to help identify source of leak on tank-type water heater
http://waterheatertimer.org/Water-heater-is-leaking.html

If you are uncertain about parts on gas water heater, I suggest calling service technician.
There are several advantages. The technician can service the appliance and ensure there is no dangerous gas leaks or dangerous CO vent leaks.
And if your water heater is rusted and leaking, then service technician can prevent a possible flood.

Some gas is heavier than air and settles to floor, so always check for gas smell near floor level.
The combustion product from a water heater contains odorless CO which is poisonous, and must be vented outdoors so it will kill other things besides you.
The service technician can also see maintenance issues since gas water heaters require yearly maintenance, and some require more frequent attention.
Finally the service technician can give you a few tricks and tips for taking care of your water heater.

If you add a comment with the brand, type and model number of water heater, I can possibly locate a manual for that product which can help both you and me understand your water heater better.

Upvote the help.
And take advantage of fixya expert assistance live.
For a price, expert works with you while you work on water heater or any do-it-yourself project.
Fixya is always less expensive than a service call.

Recently i got a hotwater heater installed in my home, i was told it was for natural gas and i believed the "experienced salesman". turns out they rigged a propane hotwater heater into my homes...


Those dirty crooks, Only kidding. They did the same thing to me a while back, except it was a natural gas heater with lp tank out in the yard, bought it from the gas co who services the tank, found out they ordered a dozen heaters, all of them natural gas. I said to the guy, do these need to be switched over or jetted or something? He says why, I said because it says natural gas only. It worked fine, just smudged black smoke out. He brought out another heater and swapped it out, seems you can't change the burner? Don't make sense. Anyway, I would take it back to the place you got it and say get up the coins, It cost $400 to get the plumber back to hook this thing up!! And we have no hot water. And my shotgun has a hair trigger. I would say it is dangerous enough to get his attention on the matter without going to court. Hope this helps.

The elbow is broken and the air from the hot water tank is leaked


Any exhaust air coming from the gas water heater is potentionally life threating. I would get it fixed. Do you have a CO2 meter close by the water heater? If it is leaking air back into the house that has CO2, after a certain amount the alarm will go off. If you dont have one get one. A must have with gas appliances.
