God bless you! Thanks for sharing your knowledge. Well done.

[@brandonmckillop3859]

I'm a plumber and I'm very good at it. I'm licensed and I always learn more from your videos. The best techs remain teachable so thanks

[@draindoctor2967]

I love how this guy is extremely knowledgeable, yet also very relatable. He may not have had his equipment in a tiptop condition for the video, but the information he provides and the things that he chooses to overlook gives this video a great sense of "real"ness /organic-ness. i love it.

[@beotheguitarist]

This is like the 3rd time I've watched this video and it's the best explanation of how water heaters work. Best on youtube!

[@rickj6048]

I admire your honesty: You're supposed to check the anode rod, the pressure relief valve, flush yearly, clean the air filter grill, but I never do. Reminds me of myself. If it aint broke it don't need fixin. I'm a firm believer of not messing with things because the manufacturer offers overkill maintenance procedures. Not neglect just common sense.

[@JWinder2012]

Great video. I know what you mean about not ever draining the tank. My parents live down off the Gulf of Mexico and have never drained their tank in over 15 years. I live in Las Vegas however, and the water is very bad and has lots of minerals and whatnot in it. If you don't routinely drain your heater here you won't get more than about 5 years out of it. It's wild. Thanks again!

[@marcobala9284]

This is hands down the best video on gas water heater. Thanks

[@gandalfthegreat5811]

Super helpful! Going to take the burner out tomorrow and clean out debris in hopes that is what is killing the pilot light. Thank you!

[@s.collins6864]

Very clear, easy to follow explanations. Great video! Thank you for taking the time to make it!

[@Bilmor1982]

Hello J!!! I'm soooo grateful with your videos, you are SUCH a great teacher. I've seen many other videos on water heaters and they either over explained or fall short on important terms. You are spot on!!! Gob bless you my brother and thank you for sharing your knowledge with us nech techs!!!

Thank you so much. We just moved into a place that has a gas heater and I didnt know anything about it. Now i do!

[@andersonjimmy1691]

Good video. Thanks. I am a fire captain and we routinely get calls for leaking water heaters. It will be a good video to show my newer firefighters.

[@condor5635]

Great video overall. Very detailed and included most all of the important items around water heater construction and operation. Thanks for posting. I do think replacing the anode rod (3-5 yrs) and draining the heater every year are important as is testing the overpressurization valve. You seem to blow these items off as not necessary when in fact they help extend the life and safety aspects of the water heater. Thanks!

[@brianaple]

I was surprised he disregarded the anode, draining, and safety valve maintenance as well. The tank manufacture screws in the anode rod and exposes the nut to remove it for a reason. I guess if you were to cut open 100 10 year old tanks you could come to a better conclusion but until someone does that I think you should check it yearly. Some people may never need to replace it but you will not know if you are one of those if you don't check it. Taking it out yearly will also making getting it out a lot easier in 10 years if it then should be replaced. As far as the safety valve goes the warning tag right on the things says it must be opened yearly to make sure it is not stuck.

[@stprk]

Best explanation about the gas water heaters. Thank you for excellent information. Great learning experience.

Thank you! Glad you found the video useful!

[@wendwag1970]

I concur thanks...

[@boonang4097]

Thank you for taking us through the hot water system. You covered basically all the parts and how they work. You even went into the heart of the system showing how to remove to check the burner. Great video and sharing.

[@WordofAdviceTV]

Thank you! Glad you found helpful! :)

[@michellerobinson4291]

Great video. Very comprehensive. Thanks. Water is coming from my Pressure Relief Valve ( I didn't know what it was prior to this video) and I didn't know what was happening. "Do I need to call a plumber asap?" From your video information, I lowered the temp on the heater and it eventually stopped. Since I am unemployed at this time, your video allowed me to understand the basics. Thanks again.

You're welcome! Thank you watching and commenting!

[@cyrilasfrenchyaz]

Good video as always, thank you! I flush mine every year and change the anode rode every 2 years or so as I have a water softner and it eats up the anode like crazy. Doing regular maintenance allows to make your water heater last more than 20 years.... my last one was still going after 21 year when I sold the house lol. All the recommendations are in the manual, worth checking.

[@unknownone8479]

My Anode is on way to tight, I'll move the water heater, sucks. I do flush every year. I also have a water softener

[@jeffspicolli593]

I love it that despite your in depth knowlege of water heaters and the reccommended maintenance that you resisted the urge to virtue signal and admitted that like most guys you have ignored the reccommended servicing.

[@shaffer4220]

Absolutely the best educational video I’ve seen. Great job!

[@JNich-yc6cc]

Great video very informative. I thought it would be funny to mention that according the international residential code not having a drip pan beneath the heater is a code violation.

[@GG-qr2mp]

Thank you for your informative channel. I am a contractor but still benefit from your videos. `I noticed on your water heater that you ran copper straight off the top of your water heater. It is recommended to use dielectric unions in situations such as this even though there is an anode rod in the tank since the tank is steel and copper is considerably different in galvanic potential and will sacrifice the higher charged metal, in this case the steel which is your water heater.

[@benjaminwallace4626]

Dielectric unions? My house was built in 01 and I had a new water heater put in 2017, old heater cracked even with draining and anode rods Why the unions if I may ask? Mine doesn’t have them

Excellent video. An neighbor is throwing away a brand new looking 40 gal. water heater from Rheem installed in 2016. She explained to me it leaked, the technician came, looked, said it is shot and replaced it. Looks like the one carried at Home Depot, model number XG40T09HE40U0. So surprised it lasts only less than 5 years.

[@kkingbd]

Thank you so much for this useful information.

[@michaelgoodman6840]

This was great! I'm having a problem where I get just 5 minutes of hot water out of a fairly new Richmond Gas Water Heater. The dip tube was replaced and my inexperienced plumber has no idea what else can cause this problem that went from intermittent to constant. Note that it is 75 gallons, that it vents out the roof and we use standard, modern faucets. I'm at a loss! Can you help?

[@positiveMind1000]

Thanks so much 🙏 nice clear and easy to understand video. Definitely will watch the ad to help you.

Nice explanation. I would like to see a video with a gas fitter to point out all the gas installation mistakes.

[@kissingbanditt]

Excellent video and explanation of how the gas water heater works....i loved it. I have a question if i may ask. My water out of the tap, specially the hot water looks creamy or rather cloudy per say. Is something in my hot water tank causing that or is there a fix? Thanks alot and thumbs up!!

[@jrh11254]

My two Bradford-White water heaters are now 16 years old. I keep waiting for the inevitable to happen. You mentioned a 40 year old water-heater which gives me hope that mine may have a chance to go a lot longer!

[@duanewaite8947]

Proper maintenance is the best way to get best longevity from your water heating unit including testing the pressure SAFETY valve. It’s not a safety feature if it is not working properly and testing it is the ONLY way to ensure safe operation. Watch Myth Busters water heater experiment

The best statement is at 5:05. "Honestly, I've never yanked mine before." LOLOL Seriously, a very helpful video!

[@derekmei6585]

Just an FYI, not sure if someone mentioned it already, but the drain valve you have there is not missing a turning knob. This type works like a ball valve, I believe a quarter turn with a flathead will open or close it. If you try to turn it like a screw, it'll open the valve real fast and you'll get blasted.

[@ronk9830]

You make two good points. I never thought a knob was missing, but the operation of the drain cock did confuse me for a few seconds when I drained mine. Others worked like a spigot, turning left and right to open and close.

[@paulhurley9475]

He showed that on the video where he drained his brother's hot water tank.

[@maranzj4471]

thank you , your information help me to fix my water heater that i have problem with in 5 days i wasnt having hot water at all . thanks you video now is good save me money,,,

[@WordofAdviceTV]

That's awesome! Glad you were able to get it fixed!

[@thebartender2008]

I got the same A.O. SMITH brand, 2006, just got my MN house in spring, yesterday did a flush, just a little bit of debris came out, so got lucky, not sure if it was ever drained. refilled at about 1/4 way then drain again, twice to make sure any crap at the bottom got out, at first had to blow thru my hose a few times to get it to drain. To make a water heater last is a Water Softener. Very informative Video, Thank you

As a plumbing apprentice, I love you

[@ep411]

Very good video, thanks for this!

[@orusahrudayan1695]

Very good video. Clear explanation without any fillers and very good video. I was able to see the pilot light and inside the chamber. BTW can you tell us where can we get such a flash light?

[@rongkaizhao7416]

Good overall explanation, with one correction, the thermal couple is not only detecting the heat on the pilot, it also powers the gas valve. There is a small voltage generated when it is heated by the pilot and it will open the gas valve. A current very small, but enough to drive the valve.

[@felixbenavente568]

perfect way to show how it work...the best

[@rbilardo47]

Another awesome video. I never took out the gas burner unit before (never needed too) but now if something does go wrong I will know how to take it apart and put it back together safely. All your videos are very helpful and informative. I thank you for sharing all of this with us. God Bless. Oh, one questions: How do you take out the sacrificial rod if it is longer than you have room to the ceiling. Mine is a 40 gal on a 19" high platform along with my heater, heater is 46" tall and that leaves me 33 1/2" to the ceiling. I don't know how long the rod is in a 40 gal unit. It's a State Select model, never heard of this, but I live in Florida, it might be popular here. Thanks for your help, I was going to attempt this last year but was afraid I couldn't get it out, even more so, getting a new one in.

[@WordofAdviceTV]

Already answered in a different comment ;)

[@beverlylong-jo2vh]

It was very good l learned a lot keep up the good work

[@maryduplessis4395]

Great video and thank you for explaining every detail.

[@VMac-eg7fb]

Great knowledge, excellent teaching.

[@NorthPaddle]

Helpful video for the newbie, but I will offer a little extra info on inspecting or replacing the anode rod. All rods have a 1 and 1/16th hex head so you'll need a big socket. Second: nearly all will require a cheater bar on the wrench to get it loose as they come very tightly installed. Third: Wrap the threads with Teflon tape to avoid leaks since that tank is under pressure.

[@joeskinwalker7628]

Great video!!! I am having a problem with my HD RHEEM water heater but i think your video might have solved my problem. My water heater has a lit pilot light but the burner will not ignite to main burner to heat the water. From what you said is the thermal pile rod needs to send a signal back to turn on the main burner. That tells me it i replace the thermal pile rod it should solve my problem i hope. I just hope it is not something in the electronic box. I will replace it an see what happens. Thanks for your video. Thumbs up 👍.

[@ciscokid1223]

Great informational video on water heaters ever

[@TedToal_TedToal]

What I really want to know is exactly how the thermostat works. There seems to be a lot of inaccurate information out there about the use of thermocouples, thermistors, and thermopiles within the thermostat. The best I’ve gleened so far is: A) A thermocouple is a device consisting of two different metals in contact with one another, which create a very small voltage (a few millivolts) when one side is hotter than the other side. The maximum current with a short circuit across the terminals is only a few milliamps, and the maximum power it can provide is only a few microwatts. B) A thermopile is a bunch of thermocouples connected in series or parallel, boosting the output voltage or current, and boosting the output power. C) The gas valve for the pilot light is a tiny electrically-operated valve that can be actuated by the minute power of a thermocouple, only a few microwatts. When you hold down the button for igniting the pilot, this forces open the valve. After the pilot light is lit (either with a match or piezoelectric igniter) and is on for a few seconds, it heats the thermocouple, which begins producing power, which is used to actuate the valve so it will stay open when you release the button. If the flame goes out, the thermocouple cools and its output power decays rapidly, closing the pilot valve so unlit gas doesn’t leak out. D) The temperature sensor and main gas valve are what I have found the least reliable information about. There is a copper tube that sticks out of the thermostat through a hole in the tank into the water. It apparently contains within it a smaller tube that contains a gas (nitrogen? air? Let’s call it nitrogen to keep from using the term “gas” for more than one thing), or it conducts heat to a chamber containing the nitrogen. As the water temperature changes, it changes the temperature of the nitrogen. That in turn changes the PRESSURE of the nitrogen (look up the ideal gas law if you aren’t familiar with the PV=nRT equation). The nitrogen pressure opens and closes the main gas valve. As the water cools, the nitrogen pressure drops, eventually getting low enough that the main gas valve opens. The pressure at which this happens is adjusted by the temperature setting dial on the thermostat. But what keeps the gas from flowing if the pilot light isn’t lit? I’m guessing that the heat from the pilot light not only activates the thermocouple but also opens a valve through which the gas must flow to reach the main burner, perhaps doing this by causing a bimetalic plate to bend and alter the valve position. But if that’s the case, why not use that same valve to provide the gas flow to the pilot light, instead of the thermocouple complexity? Maybe that is in fact how it works. But a thermocouple is probably still used to achieve the emergency shutoff described below. E) A thermistor is an electrical component made of a material whose resistance changes with temperature. There are two types. A positive type increases resistance with increasing temperature, while a negative type decreases resistance. F) Also inside the tube that sticks into the water from the thermostat is a thermistor. Its purpose is to activate an emergency shutoff if the water gets extremely hot. This is not normally expected to ever happen. If it does, often thermostats cannot be taken out of the emergency shutoff state and instead must be replaced. I haven’t been able to find out how the thermistor is able to activate an emergency shutoff. Being electrical in nature, I would think it would have to do with the thermocouple and its voltage output. Let me hazard a guess. Suppose it is a negative type thermistor, and at normal temperatures its resistance is high enough to block the thermocouple voltage from being useful. Say that the thermocouple output passes through the thermistor to another tiny gas valve like the pilot light valve. Further suppose that, were this valve to open, the gas flowing through it would create a pressure against a moveable rod, causing it to slide outwards away from the gas pressure, and slide across a channel through which the main gas flows, blocking its flow. If the water temperature gets extremely high, the thermistor resistance drops low enough that the thermocouple voltage opens the valve, forcing the rod to slide and block the gas flow. That might work. Although, one can imagine a purely mechanical emergency shutoff, again using a bimetallic substance, this time having its flexure move that rod to block gas flow. In either case, it would seem necessary to arrange that sliding rod to trip suddeny rather than move slowly to block the gas flow. If anybody can point me to a detailed and accurate source if information about how a hot water heater gas thermostat actually works, that would be great!

I loved this video! Thanks so much. I have a question though, how come you don't have a drain pan to catch leaks? They make water alarms that can let you know if something is wrong.

[@WordofAdviceTV]

Those are great to have! But many water heaters don't have a drain pan because they are located next to a floor drain so even if there is a leak it is very unlikely to cause any damage.

Thank you for your video was very helpful now I have a question I have a brand new water water heater in what happen is is making a lot of noise why can't I do

[@robertgift]

You *_should_* flush the wateheater. Keeps it morefficient. May help the tank last longer.

[@MuhammadShohaibHassan]

That really was a great and comprehensive introduction of how Gas water heater works. I am actually here to find out some way to automate my Gas water heater. I currently need to light it On and Off everytime, I need to use the hot water. By anyway, Can you guide me to correct direction. I am in need of a module, which contains a electric spark module, a electrically controlled thermostat, which can be operated by a software and a remote connection like a Wifi or Bluetooth controlled device. Please guide me in the right direction.

[@motorhomediaries231]

That's what I call a complete explanation. By the way, the spark mechanism is actually called 'piezo-electric spark generator'.
