How to replace an electric water heater. The Home Mender


Hi this is Dustin Luby with Home Mender
inc and you can find us on the web at homemenderinc.com. Today, we are going to change out an electric water heater Pretty basic .Pretty simple so we’ll get
it knocked out. First thing we’re going to do is turn off the breaker at the
panel usually labeled “water heater”. Obvious and then we’re going to kill the
cutoff on top of the water heater. Next, what we want to do is take a garden hose, hook it up here running out to the driveway. Turn on the valve. Open it up.
Drain the water heater. If we don’t we won’t be able to lift it. After we’re
sure the water is off, powers off, we’re going to go ahead and start taking it
apart. so we’re going to cut off this pipe insulation here and get this free alright and then just throw that in the
floor. Okay we’ve got the insulation off.
Generally, there’s only one cut off. That’s going to be your cold line so there’s
cutoff to the supply to the water heater brings in the cold, water warms it up,
shoots it out. If you don’t know which one’s hot and cold just feel it. Oh, that’s hot. So then we’re going to take a tube cutter. Pipe cutter
and then cut the pipes. Let’s go ahead and sure this thing is empty. After you got it draining a little bit you gonna want to open up this pressure relief valve.
It allows the water to flow out a little smoother by venting. Alright, we’re
going to go ahead and disconnect the electric supply to the water heater.
Again, make sure it is a shut off at the breaker box. Okay and we are going to
disconnect. I always like to cap the nuts back. You
know, just in case. You also want to test after you cut it off. You’ll want to
test to make sure that it is actually off otherwise you are just relying on
someone else and hopefully they did their job right and labeled it correctly.
Not something to play with so we like to go ahead and test it anyway. After we
think our water heater is drained, we’re going to use our pipe cutter
to go ahead and cut the pipe. rocket science You can’t cut that with anything else besides a specialized tube cutter
otherwise you will bend or you know flare out the pipe then your fittings
won’t go on. My pipe cutter sucksI I will be purchasing a new one after this
job. Alright and we are through and then we’re going to go ahead and do the hot
side. Alright! We are through.
Now we can try to lift this guy out of here. I brought along a dolly. It’s going
to help. Alright this guy’s is still pretty full but since we’re in a garage, not a big deal. No chance of damaging anything. We’re going to go ahead and
wheel it out. Once we get the old water heater out we got to put the new water heater in so here it is. It’s nice and pretty we do want to make sure that our electrical
line is gonna be long enough to reach it. Also, you want to make sure that your
hose bib where we drained the water heater before is accessible. Here it isn’t a
problem but sometimes they’re you know closet or something so you want to make
sure you can get to that for the next time. Alright, we want to take some
sandpaper cloth and go ahead and clean up our supply line. Get it nice and
pretty. it’ll shine it up
it’s like grandma’s brass. See how pretty now ? and voila. I’m going to go ahead and
do the other one too right now we’re just working our ground line over top of
these screws we can tighten it down secure it. Alright. We are in. Now we’re
going to connect the power. usually the water is labeled if they’re
not hooking them up exactly how you found it is a good rule of thumb. Now cram the 10 pounds of wire into a 5
pound hole. Alright. Now that our electrical line is
wired and secure, we can go ahead and run the supply line .Alright, I’m going
to be using a 3/4 inch steel braided sharkbite fitting connection which is
amazing. They’ve got these little push on fittings. Push in pull it back to lock it
secures it. Very sweet. So push those on, pull them down the lock it and then run this.
Make sure you run your supply line, obviously, to your cold. You don’t want to
reverse it or anything. The water heater is usually labeled on top hot, cold or will be labeled with a red or blue something or other. Alright we’ll go
ahead and snug these down in a minute. Let’s do our hot side. Again, push up, pull down and it’s locked. They’ve already got washers inside them
so there’s no need to teflon or pipe dope the nipples or anything like that. So we’re going to snug them down. Alright, we are completely snugged. So
we’ve got our electric wired. We’ve got our supply lines run, so what we’re going
to do now is turn the water on. Our water supply line is back on now. You can hear
the water heater filling up so while we wait for that to happen. All
right while we wait for our tank fill up we’re going to go ahead and run the
pressure relief valve line. By code these need to be extended within six inches of
the floor and we’re always going to do things to code. So what I’ve got here is
a three-quarter male fitting copper so we are going to sweat this line on here.
Alright good and clean . We’re going to take some recto seal thread sealant also
known as pipe dope and we’re going to dope this and we’re going to dope the
inside threads of this guy , too. Oops.
After that’s done, we’re going to go ahead and put this guy on there. Alright . Tighten him down. Alright. Get him good and snug .Now the
fun part .We have some… after we’ve cleaned our fittings,
we’ve also cleaned the end of the pipe that’s going in there ,we are going to
sweat this on there with or solder this on there with a little bit of flux. We’re
going to put the …we’re going to put the flux inside the fitting
here and on the part that’s going to be connected to the copper line. You want to
use a clean brush. This brush is not clean so we’re just going to make sure
we don’t get any crud in there. The flux helps the solder to flow a little better so this guy’s going to go right up in there. We’ve got our torch. A little bit of
solder. You always want to heat up the fitting, not the pipe. Alright and there we have it. Alright,
now that we got our electric connected, we’ve got our supply lines done .We’ve got
our pressure relief valve line run within six inches the floor. We’re going to
go ahead and turn on the breaker and hope nothing explodes. That should do it.
Now your elements are warming up. Our last step which I’m not going to take you in
there and do is we’re gonna bleed the lines. Open up the hot water on the tubs.
Open up the hot water on the sink. Basically, just gets the new water
flowing through so where you won’t have a lot of coughing and hacking when you
turn on your water. That’s it! The water heater’s installed. Lines inside are bled. Electric’s back on. Water is heating up as we speak.
All in all, it took about 35 minutes so all that’s left to do is clean up the
mess. You can choose to clean up the mess or not. Sometimes I do. Sometimes i don’t. No, I always clean up my mess but that’s it so for homemenderinc.com, I am the Home Mender, Dustin . and I will see you next time.

  1. A good thing to answer on here is how long does it normally take to completely heat up a 40 Gal. Electric hot water heater?

  2. Hey, the water was off for a few days so the pipe wasn't hot, what would happen if you hook hoses up wrong

  3. Why did you install the threaded pressure relief valve before soldering the base coupling on the top of the water line first? Thanks

  4. Thank you! Simple easy repair it looks like. Was going to have my home warranty company repair or replace or W. H. but I don't think the package we have covers sediment. We have a lot of sediment in our water here so i was told i could add a bigger drain with a valve to flush the tank often. What do you think about doing this?

  5. should warn people never to turn on power until heating elements are completely submerged otherwise you can prematurely burn the elements. otherwise, good stuff

  6. I love these videos where the tank is in a big room where you have endless room and light to work,….everybodys happy !!

  7. lol, you just pipe doped a pressure valve…………….. overkill. That valve never gets any pressure at that point. If it opens, it opens into an open line.No back pressure. Btw, if you are not experienced and watching this, make sure to sweat the pipe and fitting on the relief valve before you screw it into the relief valve.If you heat up the relief valve it will fail.

  8. When draining the water out, at the start, first shut off the cold water supply to the heater. Then open a hot water faucet in the house so it drains faster.

  9. You really should solder BEFORE putting the pipe on the tank if the soldering is close to the tank itself. Not as big of a deal for the T&P relief valve, but it is just good practice to prevent tank damage.

  10. I which to have here in Texas. So you can replace my water heater since is making noise while using the hot water . The noise is like rocks running inside the boiler .

  11. Great video. Woke up this morning to water all over the floor. Heater blew a hole out the side last night. I guess asking for more than 14 years was just asking for too much…

    I will be doing this job next weekend and wanted to see a couple vids of it being done. Yours was simple to understand and easy to follow. Thank you.

  12. I think I would have first sweated the pipe onto the fitting to thread onto the overflow valve as to avoid cooking the pipe dope! But still I like your video & thank you for your sharing it.

  13. Do you remove the plastic plugs that are sticking up out of the cold and hot water nipples?
    Awesome video. Thanks a lot.

  14. I found this video today and successfully replaced my water heater, just FYI hardware stores also sell the couplings to attach the pipe for the overflow valve, so now no soldering needed. I saved 450$ on an install from a plumber, YEAH!!!!
    Thank you home mender!

  15. For being so polite and answering my question so fast, i give you a thumbs up, and i am now a new subscriber. thanks man.

  16. What’s happened with my situation is …. bought a trailer. When we bought it, during the tour they made it a point to just show the top of the hot water heater. At the time we thought nothing of it. A year later I noticed my bedroom was dripping water from the wall. “By the electrical box” 🤦🏽‍♀️ after pulling down the wall, noticed that whoever had the place before us had four towels around the bottom of the water heater. Now Saturday we are removing our old one and replacing it. It was in such bad shape that the bottom boards were rotting from under it. 🤦🏽‍♀️ thanks for the video. Very helpful

  17. I have a small electric water heater inside a closet in a mobile home… besides the perforations on the floor for the pipes all the pipes and connections?… do I need to do one more perforation/perforations on the floor, just for ventilation so that some cold air might come through it to the inside so that the closet doesn't get too hot?.

  18. My tank came to my house today and I got itchy to get it installed rather than wait for a plumber. I followed your video and another video that has some very good precautions about making sure the tank is full before turning on the breaker, etc… I used Sharkbite hoses for water heaters, and the removal and install took 40 minutes. I just took a seriously delicious HOT shower… There are zero leaks anywhere, no undo pressure and no unusual heat radiating out. In addition, the wiring meets the specs of the tank and was insanely simple to conjoin safely… Great vid…

  19. Thanks Dustin! I just bought a new water heater yesterday and need to install it. You're video is exactly what I needed! very informative and helpful, couldn't have done it without you! Handsomest "How-To" ever! 😉 Thanks buddy!

  20. I was cool with it up until flex line with rubber gasket against 150 degree temps. Im no plumber but I like neat job, so I woulda sweat the fitting UPSIDE RIGHT so solder seeped into crack. I just thought you were working against gravity, is all. Painting the solder looks ugly. Not to mention when you sweat the fitting attached to appliance, well… Everyone already told ya.

  21. Awesome video!! I did everything as you did and same lines to the same cold input and hotout, I have no hot water going in to the house but water heater has got water and my cold line is hot, is that normal?

  22. This is an ok video but, I'm not a plumber and jus learning how to dyi alot of things myself. What I've got is I'm sure not up to code and it's all a mess and very confusing. Wanting to change that.

  23. I used your video to install my electric water heater today and used the shark bite hoses. Easy install. Thank you for the video.

  24. Should you ad new shut off valves while your installing a new water heater and can you use shark bites to go from copper pipe to pvc pipe or pex to make the water connections

  25. Now I feel comfortable replacing my heater $500 for a new one and some lines and fittings VS the 1050 the plumbers were quoting me.

  26. I just subscribed to you're chanel i got to redo my daughter's bathtub so if you can do something on that i would appreciate it

  27. NEVER solder male iron pipe with dope on it!! Never solder them in any type of valve!!! Doesn’t matter if you are deliberate with the heat you never do it regardless. I’ve been Pipefitter for 17 years and I learned that the first year of my apprenticeship. You should seek professional training.

  28. The copper line downstream from the pressure relief valve is usually plastic in Canada . Since it’s a drain, there isn’t any real pressure build up. If the valve ever opened it just allows water to drain out the open end of the plastic tube. Simple. No soldering. Cheaper.

  29. Let me ask you a question what if you still have the old time boiler combo with the hot water intake would new boilers still work with it and how do the new boilers work compared to the boiler combo with the water intake

  30. Perhaps the earlier person who posted regards sloppy job probably did not see the VDO closely or failed to notice that the pipe has to be attached to the appliance and also the cold inlet water supply was turned on before the breakers were switche d on..

  31. If you are gonna call yourself a plumber……please do us plumbers a favor….and revaluate you life choices.

  32. Best video on here I was going to pay $150 to R&R the water heater. Saved me money for car parts. Thanks!!!

  33. Just watched your video on installing a new electric water heater. Thanks for the info. Need to change my heater also. Your video helps like a check list before I install my heater too.
    Thanks again. Good video ! Look forward to watching more of your videos.

  34. All the videos I see use the plastic pipe material to install water heaters but the guys at lowes and home depot are telling me that I can hook the sharkbite connectors directly to copper pipe. Does anyone know if the Sharkbites will create a seal if I hook directly to copper pipe. Can I use a Sharkbite to install shutoff valve. Mine is on the top not the side and a copper pipe is attached so I would need to cut it. Thanks
