Answer #2 \n. \nInsofar as the unit is only two years old, it is not likely the rust or sediment is coming from the corroding interior of your unit. It's getting in there from the cold-water feed. If your house is supplied by old iron pipes, that could be the source. Or if your house is suppli…ed by its own well water, the depth of your well may be inadequate and you're picking up water with high iron content. If you have municipal water, maintenance workers might have disturbed the lines upstream and loosed some debris and sediment that wound up in your tank. When you experience a problem, ask your neighbors whether they're also having trouble.\n. \nIt's always a good idea to drain a few gallons out of the tank every six months or so. I also check the pressure relief valve at that time.\n. \nSome people also recommend checking the anode bar. That's in there to prevent the inside of the tank from corroding; the bar corrodes instead. Not sure that it could be depleted so soon. But if your water company isn't good about maintaining adequate pH and whatnot, perhaps it might be. But for a unit that new, I suspect an outside culprit.\n. \n Answer \n. \n. \nsounds like some rust in either the pipes or water heater...i would let the water run awhile to clear it up...if that doesn't clear it up contact a plumber or you local water dept.

Answer . Not much of anything. Drip legs were quite common in the past, and many cities and engineers still specifiy their use. They are intended to capture any condensed water that may have been transported in the gas. If you don't have a drip leg, I'd not worry about it.. I was flagged for thi…s in the Borough of Magnolia in NJ and had to install one to obtain a Certificate of Occupancy. You can call the township you live in to see if it is required. (MORE)
This is usually caused by a bad thermocouple. The thermocouple looks like a thick, solid copper wire screwed into the gas valve on the water heater. The pilot flame heats the tip of the thermocouple, causing it to generate a minute electrical current at low voltage, which provides power to an electr…ic valve that controls the flow of gas to the main burner. If you attempt to relight the pilot burner and it refuses to stay lit when you release the button on the gas valve a minute, or so, after the flame has been lit, the thermocouple is the most likely cause. Replacement thermocouples are readily available from most hardware stores and can be replaced by the homeowner, using simple tools, by following the instructions on the package. . Another cause of the problem could be a lack of air to the combustion chamber. Newer water heaters require more volume of air due to the addition of a heat sensitive diode to the thermocouple. Not enough air flowing through the combustion chamber to carry the heat up through the flue causes heat build up, which kills the thermocouple. On my water heater, I could light the pilot and the water heater would burn for 20 minutes or so and shut off. The fix included routing the flue straight through the roof and opening floor to allow more air into the water heater compartment. . Another possible culprit may be water-heater vent height above the roof. In some situations this may periodically result in a downdraft that could cause the pilot light to go out. If this is the case adding to the vent height may help. Note: building code states that the B vent required height is based on the roof pitch but it must be 2 feet higher than any portion of the building within 8 feet of the vent. . Make sure the vent cap isn't missing or rusted through on the roof, it will cause drafts and wind to blow out the pilot. (MORE)
\n. \n Answer 1 \n. \n(1) the gas is cut off; (2)the pilot light blew out and is not igniting the burner; (3)the thermostat is set too low for your requirements; (3)the thermocoupler is bad; (4)the pressure relief valve is stuck in the open position and discharging the hot water. 1,2,& 3 are …self-explanatory. The thermocoupler is a bullet-shaped sensor located near the burner - it senses the temperature and turns the gas on or off to the burner according to the setting of the thermostat. The pressure relief valve is usually located at the top of the water heater on the hot water line and leads to the floor and under the house (separate from regular service hot water line) - it opens when the temperature of the water is too hot and discharges the hot water to keep the heater tank from over-heating and exploding. Hope this helps.\n. \n. \n Answer 2, One Correction \n. \nAnswer one is very good, but there is one error which requires correction. The thermocouple does NOT, as described in answer one, act as a demand thermostat for turning the main burner gas ON and OFF. The demand thermostat probe extends from the back of the gas control valve INTO the water INSIDE the heater tank. \n. \nOn the other hand, the thermocouple is located so as to be IN THE PILOT FLAME. Its purpose is to determine the presense of the pilot flame, and if the pilot flame goes out, the thermocouple will cool down, at which time, it TURNS OFF the gas TO THE PILOT. \n. \nThis is a safety feature designed to prevent the continued release of gas, which which if gaining contact with an open flame or any spark, would result in a devastating explosion.j3h.

Two years 11/2 months and 3 days and 41/2 hours approximately. It has to do with how many thousands of gallons are in the tank , how many are being drawn out and what the BTU input is of the fuel being used 100 litres at 60 degrees Celsius = 1 hour (2kw element) 150 litres at 60 degrees Ce…lsius = 1.5 hours (3kw element) 200 litres at 60 degrees Celsius = 2 hours (4kw element) 250 litres at 60 degrees Celsius = 2.5 hours (4kw element) provided all are using 220 volts of domestic electricity (MORE)
By calculating the the load required on the existing gas piping to make sure you can get complete combustion so no one gets asphyxiated and double check the flue requirements so there is no possibility of spillage of toxic fumes
Answer . [Note: There are critical safety concerns involved here. Read the whole answer!] . I'm no plumber, but I do know this:. You need to determine if your water heater is designed for side venting or verticle venting! . If installed improperly, the water heater may allow deadly carbon mono…xide into your home and possibly cause a fire! . I think this one is best left up to a professional. Hope this helps. (MORE)
NOT if your on a water supply dependent on electrical power for a water booster pump
There should be no more than six inches between CPVC pipe and theexhaust flue on a water heater. If the CPVC pipe is installed tooclose it can be a safety issue.
Unless you are VERY comfortable working around gas - call a plumber your life is worth more than a plumber will charge you.
There are a few possibilities. One is that the water heater is not large enough for the demand put on it. Another is that it is not turned up high enough. Another is that your shower and bath valves are preset so as limit that maximum temperature. These can be adjusted and how to do it is dependent …on the type of valve. Typically you have to remove the shower valve trim to get to the adjustment screws. Some Delta brand single-control pressure-balancing valves have a stop disc hidden under the control handle that can be rotated left or right in fixed increments to set the maximum temperature. Another reason is calcium buildup at the bottom of the water heater which impedes its ability to heat water efficiently. This can be mitigated by opening the valve at the bottom of the heater and shutting off the hot water outlet valve on the top. I like to drain it a bit and then turn on and off the cold water supply to surge and lift the sediments off the bottom so they will make their way out the hose bib at the bottom of the heater. If you have very hard water in your area, the tank may require deliming after a few years of use. Remove the hot water fitting at the top and drain out half the water. Pour de-liming granules (a weak acid) into the hot water outlet with the aid of a funnel and turn the temperature of the heater up to its highest setting for an hour, or so. Turn the heat off and let the hot acid solution work for a while, then drain the tank, reconnect the hot water fitting and flush it out thoroughly via the drain valve before setting the thermostat to the normal temperature and returning the tank to service. Deliming granules are available from many hardware stores. You might consider replacing hot water tank with a tankless water heater. It pays for itself in a few years, but will require a dedicated circuit, if electric, or upgraded supply pipe, if gas. Tankless heaters also have a tendency not to turn on at low flow rates, thus providing no hot water at all, and giving up a water tank is also loss of an emergency potable water supply in case of a natural disaster.

Yes i would say, i can have a 30 min shower of hot water, it also depends on the size of your hot water tank.
Because someone did not take the fixture demand into consideration and the ambient temperature for heat loss calculations
Usually yes. The air/fuel mixture ratios are different, so you most likely need a different fuel orifice. Most of the water heaters I've dealt with you can buy a conversion kit with the lp orifice from the manufacturer, usually not too expensive. Get the exact model number for your heater and then …Google it or take it to your friendly plumbing supply. (MORE)
Shut off fuel supply. Allow to cool. Close the inlet and out let valves. Open the drain valve bottom of heater. Open the T&P to break Vacuum. Have a hose attached to dump water in a safe area. If you are draining heater to flush don't shut off fuel supply. On a power vent heater (pvc venting) you ca…n turn the switch off. On a conventional heater with metal flue pipe turn to the vacation setting (lowest temp setting). when your heater is refilled you can switch on or turn temp setting to original position without bleeding gas and relighting. Waiting for a sitting heater to cool will take hours. You can run hot water in house with heater off until cold. You should not have an outlet valve on a hot water heater if you do remove it. Open hot water in building to vent. Opening and old T&P will weaken the spring even more so if hot water runs through it and may cause it to fail (drip) later with water on. Some drain valves drip later with water on have a 3/4 garden hose cap with washer for valve if it leaks as opposed to replacing drain valve. (MORE)
1- Is the piping insulated . 2- When was the heater serviced . 3- Is the heater properly sized for the fixture unit demand
Only if the pipe diameter is large enough to handle the extra BtU demand or you will have improper combustion and CO will kill someone
Not for a licensed master plumber who knows to check for carbon monoxide and checks up draft to make sure there is no spillage and checks the size of the gas piping to ensure enough volume for proper combustion
Check the manufacturers specs or gas code book. TSSA B149.1 installation of natural gas and propane appliances if you are in Ontario Canada.
It shouldn't. Gas continually heats the water very quickly, so you don't really run out of hot water at all, where with regular heating it takes a long time to heat new water. You should get the person who installed the system to doublecheck, and possibly they can explain why it is happening. It co…uld be the dip tube of broken or you could have alot of hardness build-up in the bottom of the tank. (MORE)
Most thermocouples are held in place at the pilot light by pushing them into a clip that grabs it on both sides. The control end is held in place by a nut that the shaft of the thermocouple goes through.

if its not a forced air water heater then yes its should be hot but not red hot.
residential? commercial? new ? replacement? if its a new water heater in a new home then the easiest way is to buy copper flex's and a gas flex and make sure you have low pressure gas at your gas stop like around 10 to 14" water column. Make sure you have a cold shut off on your cold water line befo…re you hook up to the water heater and in some states they require a expansion tank. One good rule of thumb is if you have a check valve somewhere around your water meter or if on a well by your pressure tank then its a good idea to put a expansion tank. (MORE)
Thermocouple is most likely the problem but it also can be wind and draft which blows out the pilot light and very rare it can be you have a air pocket in your line or sometimes condensation can drip on the pilot. If you have a flame when starting the pilot light as you are pushing down on a non for…ced air gas water heater and the pilot goes out after you release the pilot handle then 90 out of a 100 times its your Thermocouple. If you have a forced air tank type gas water heater it can be a lot more sophisticated and I recommend you read your manual trouble shoot guide and follow those steps for YOUR specific water heater.

you have a question that can have many different answers . here is a list I would check first to your problem. 1. is your pilot light out or if a forced air WH is it plugged in with power to it? 2. Is your gas line on or do you have gas to your water heater? 3. look up your water heater manual guide… and go through the trouble shoot guide list because the rest of the problems are so different from so many different kinds of water heaters and not knowing what kind of water heater you have it is impossible to answer.

Standard meter will suffice, need to know pressure from meter to house. Size pipe appropriately for gas pressure coming into house X distance to water heater. Gas company or plumber should be able to help with this calculation.
Usually this is a good sign that you will need to replace your HWH soon. If your HWH is 15 - 20 years old, you will realize a savings in your gas bill when it is replaced. When you replace your HWH it is a good time to adjust your water temperature and insulate the pipes (at least the ones that are …easily accessible); it will save you considerable money. (MORE)
I'm not sure if you mean butane or LP? If you mean LP then the orifice size must be changed to accomodate the new fuel type. If you do mean butane, I can't answer that question.
A straightforward swap of a like make and model from the existing model, if all the parts,valves, strapping, are in good condition and the codes are met. A licensed plumber in the Los Angeles area will cost about $1200-$2000 for a 40 gallon gas water heater. Including the heater.
1- Tank rusted out 2- Ambient temperature has lots of humility and when hitting the cold meter of the tank it drips 3- T&P discharging 4- galvanic corrosion as someone did not install a dielectric fitting to prevent electrolytic action
Leaks can be caused by all kinds of things: . Sediment in the water heater can cause the pipes and pipe fittings to erode or can build up around the pressure relief valve and cause a leak there . Excessive pressure can build up in the tank, tripping said pressure relief valve . Drain valve can… loosen and water can leak out from there (MORE)
The only power used by a gas water heater is the small current generated by the thermocouple that keeps the gas valve open. It comes on mechanically when the water temperature drops. You don't need house current.
Have gas line and all gas fittings and connections at water heater checked for gas leak. Should not smell gas at water heater.
Depends how much plumbers charge in Seattle. -It takes about 3 hours to install a gas tank if it's a straightforward installation and no other pipes or obstacles are in the way. (I do many)
Yes you can if it sits heating for a couple of weeks without use. Open a hot faucet for a minute or two to release this with no open flame nearby,.
sounds like may be to much heat. if its coming out of the pressure relief valve located on top.turn heat down, you said coming out the valve i thinking you mean the valve on top of heater.if so thats it. faulty valve or water is getting to hot.hope thathelps
Installation instructions come with tankless water heater, but would recommend someone experienced enough to install.
It takes about 2-3 hours . I install many and really the hardest thing is finding room under the average kitchen sink.
Generally it's a 2 hour job, sometimes 3. - So it depends what plumbers in your area charge. Get estimates from 2-3 of them before deciding.

Natural gas is more thin than air, which means it is not as flammable and will more likely go up in the atmosphere. Although it is non-toxic, one should still make way for ventilation avoiding suffocation. Natural gas is clean and efficient. It is surely one of the safer options to bare in mind.
One can purchase a gas hot water heater on various websites like Amazon or eBay. One could also visit a local furniture store and ask if they have one for sale.
