in this video I'm going to show you how
to install an electric hot water heater
and if you're new this channel my name
is Joshua team is all about building
your house same ton of money so be sure
to subscribe ring that Bell so you get
notification airtime release new video
and Hammer that like button for me
that's all I asked me in turn for making
this video installing one of these isn't
too difficult so let's get started if
you have not yet purchased your hot
water tank I want to go over a couple
options you have you can get what's
called a tall hot water tank that's what
I got here as you can see it's about 60
some inches off the floor and then they
make a shorter one that's called a short
tank that's going to be a little shorter
and a little bigger diameter but it will
still hold the same amount of water
obviously if you get a 50 gallon it's
going to be a tall one or a short one or
in a 40 gallon is going to be a short
one or a tall one vice versa so it's all
depending on the area in which you got
to store your hot water tank so as you
can see I'm going to be putting this
back in this closet so a tall one is
going to work great and also if you want
to look at different size tank tanks
typically if you got a household of
about two people a 30 gallon tank spine
if you have a household with three to
four people a 40 gallon tank will work
if you have a household of four to five
a 50 gallon tank would probably be
sufficient and if you have a household
of more than five people then you
probably want to go with the 75 80
gallon tank which is a pretty uncommon
but they are out there all right let's
get to installing this thing this hot
water tank is being installed in a new
construction house and I don't have the
water turned on yet so if this was going
to be installed and the house has water
on be sure to turn the main water supply
off to the house so you don't make a
mess before I make my connections to the
hot water tank I always installed what's
called a hot water heater pan and this
is going to be a safety net in case the
hot water tank leaks it's going to
direct the water down to the crawl space
and most pans will come with a fitting
like this it's going to have a rubber
gasket and then a nut that's going to go
over it to hold it into place and it's
going to have a hole that's already
pre-cut into the side here so I'm going
to first install this fitting onto the
pan in order to install this fitting we
just take this nut off and then as you
can see the Rubber seal is going to stay
onto this and for a little extra
security I'm actually going to put just
a little bit of silicone right around
that rubber it's probably a little bit
of Overkill but I figured since I had
some on me it'd be a good time to use a
little bit of it so I'm just going to go
right around that fitting
and then we're going to go ahead and pop
that right through this side it always
helps to get this a little straighter so
that way it's going against a flat
surface if it's these metal pans like so
so it's going to go into it like that
then just tighten that nut right onto it
it's where I want the hot water tank to
set and I want my drain to come out in
the back corner of this closet and in
order to drill the hole out I got an
inch and a quarter drill bit here and
the pipe is a one inch pipe which
already purchased so the inch and a
quarter is going to be for the one inch
pipe so I know I want to drill a hole
right here in the floor
[Music]
all right now the hole is drilled out
and let's clean this up real quick I'm
now going to take an elbow in order to
go down through the floor and place in
the center of that hole and set it into
place and I know the piece of pipe I
need to cut is going to go an inch into
this fitting and an inch into this
fitting so the distance in between I got
about an inch so I need a three inch
piece of pipe cut in order to get to
this hole and then I'm just going to
extend this down about a foot in order
to get past the floor joists I'm now
going to take the Stick of one inch pipe
and get a three inch piece cut and then
again I know I need at least a foot here
so it doesn't have to be exact just as
long as it goes below the floor joists
so I'm just going to cut off about right
there I'm now just going to take my pipe
cutter and cut them in those marks
I'm now going to glue all three pieces
together and I'm going to be using
medium clear PVC cement and I'm not
going to worry about primer because this
isn't really a true plumbing job this is
just a simple drain
[Music]
I'm now going to glue this into the
drain onto the shower pan
we got to make sure we are pointing down
going straight through the floor and
just say or where if you're installing a
hot water tank in a basement you would
just route this to your nearest drain
but in this case we're going straight
through the floor here so I'm going to
place this down in through that hole and
I'm going to get this flat on the floor
[Music]
I'm now going to place the hot water
tank on top of that pan and I'm going to
get a Helper to help me do this
all right now we got to make connections
to the hot water tank often times in
order to install your hot water tank
you'd have to buy these dielectric
nipples and the reason why you would
have to get these is because it wouldn't
have them on the tank like this tank
does and if you have two different
Metals coming into contact it would
cause corrosion so there's always a
nipple between the hot water tank and
your flexible lines it's going to hook
to these PEX pipes so I just want to let
you know that and oftentimes they're
coated in this plastic PEX Coating in
order to cut down on corrosion there as
well but if you did have to install
these the how you would do it is you
would use a pipe wrench and wrap these
in TEF tape and then just tighten them
onto the tank so it's pretty simple
process but with this one I don't have
to do that in order to connect the hot
water tank to the PEX pipe I got the
SharkBite hot water tank flex hoses and
these are very easy to and install in
fact they're probably one of the easiest
Flex lines to install because of the
shark bite fitting and I wanted to show
you guys how to do this because it's a
very simple DIY project and a lot of
people are familiar with them and the
tools that we're going to need to do
this is a crescent wrench or a wrench
that's going to fit this end and we got
pipe dope that's going to give us a nice
seal and we got Teflon tape you can buy
these Flex lines as a kit or separate
and if you want to buy these exact ones
I'll put a link in the description below
in order to purchase them and as you see
there's one with a shut off valve and
then there's one without a shutoff valve
the one with the shutoff valve is going
to be installed on the cold water side
and the one without the shutoff valve is
going to be on the hot water side the
reason why that is if you ever have to
drain your tank and replace it for
whatever reason you would shut the valve
off on the cold side drain the whole hot
water tank and then it's going to drain
the water out of this line with it so so
you don't really need a shutoff valve on
this side but if you want to put one
there as well that's totally fine but
I'm going to start by installing these
onto the tank because these pipes are a
little bit in the way I'm going to go
ahead and cut these back some I'm going
to leave plenty of length because I
still got to cut them to an exact length
here in a moment so I'm just going to
snip these off
if you're wondering why these were
connected to begin with it's because I
had to pressure test my whole house for
inspection and that is an easy place to
connect the hot and cold together to
make it a closed system and if you want
to check out that video I'll put a card
in the top right hand corner of the
screen so you can see how roughed in
this whole house the first step to make
the connection between the flex line and
this nipple is to take teff tape and we
want to go in a clockwise fashion so
that way when we tighten up the flex
line it doesn't remove the TEF tape and
I usually wrap this around here about
six or seven times
in order to add a little extra security
I do like to use pipe dope or joint
compound when installing my Flex lines
and this usually doesn't require too
much to get a good seal
I'm now going to use the pipe that does
not have the shutoff valve and install
it on the hot water side
after I can no longer hand tighten it
I'm going to use my crescent wrench and
tighten it up to make sure we get a
great seal
okay
and I recommend securing this to where
it's just very snug you don't want to
ever tighten this and if you do hook up
your water and there's a slight leak
it's easy to tighten this up a little
more so that's all there is to
connecting the line to the tank I'm now
going to install the flex line with the
shutoff valve on the cold water side and
I'm just going to repeat the same
process
[Music]
I'm now going to bend these Flex lines
down to that water line and I'm going to
Mark right at the end of the hose so
that way I know where to cut my pipe and
as you can see I'm almost up against the
wall but we don't cut it clear back here
to where this is we actually are going
to mark this end right at the end of the
SharkBite fitting and then we're going
to measure back off that Mark
technically 1.13 inches in order to
compensate for the amount of pipe that
has to go into that shark bite fitting
so I'm just going to go a little over an
inch and make a mark so about 1 and 1 16
onto this pipe so that is exactly where
I got to cut this pipe off in order to
cut it off precisely there I'm going to
put my pipe cutter right up to that PEX
pipe and squeeze it together tight and
then we're just going to slowly ratchet
that down until it cuts it off and these
pipe Cutters leave a nice smooth cut as
you can see just make sure it's nice and
square now I'm just going to double
check to make sure the pipe is very
clean where it's going to be sealed at
and that looks really good nothing wrong
with that and now if you don't have a
pipe cover that will cover up this rough
opening get one that's going to go over
after the fact like I got to do because
I don't have one to go over it right now
but so you don't have this nasty look I
would put a cover that's a flange that's
going to cover that up I'm going to do
the same on this side we're going to
pull this down and mark the end of the
pipe and then we'll have to measure back
in order to get the proper distance
in order to get the shark bite on
correctly I'm just going to lean the
tank back a little bit and then place it
onto that PEX pipe and push it right
onto the pipe and make sure we go clear
up to that original mark
right that felt like it went on nice and
snug and now I'm going to do the same to
this pipe and you can reference your
pencil Mark you made originally to make
sure you're in all the way and we're
going to do the same to this one
and then push all the way on
and that feels really good so that is
exactly all you got to do to install
your water lines together and just so
you're aware these are three quarter
inch water lines and some jurisdictions
you may have to install an expansion
tank on the supply side I don't need to
do that in my area and that's because
there's no closed system in the plumbing
to where it's going to build up pressure
in the water line so out where the water
comes in or anything I don't have to
worry about that so always check your
local building codes I'm now going to
address the wiring and if you don't feel
comfortable doing your own electrical
work or even your own Plumbing work hire
a professional I'm going to open up my
panel box and locate the hot water tank
on The Ledger here and it corresponds
with this breaker and as you can see
it's powered off and I wired this panel
box myself you want to see how I did
that you can check out the link in the
top right hand corner of the screen but
I do have a double 30 breaker because
that's what's required to power that hot
water tank so it's already turned off so
I'm going to go ahead and set this panel
box and double check that that wire is
turned off I'm now going to turn on my
voltage tester and this is very easy to
use all I got to do is touch the cable
and go right around it and if it doesn't
light up and start beeping that means
there's no power to this cable so as you
can see it's good to go but never rely
on these this is just a good way to
double check to make sure the power is
off so it's just a good reference tool
so now that we know there's no power in
this cable I'm going to go ahead and
bend it down into place and I'm aiming
for right here where these two wires are
stubbed up through the hot water tank so
now we're just going to fold this right
down the wall and I'm going to trace my
water line here and then we're going to
go bend it right over into place I'm
going to use what's called a 3 8 Romex
connector and these are pushed in to
secure them they're very easy to use use
we just lay it right into the slot where
we need to install it and we just kind
of rotate them with a pair of needle
nose until they're secured and now I'm
just going to fish this electrical wire
into that Romex connector
now that I got plenty of wire into this
junction box I'm just going to tighten
up the roomx connector
and that's going to hold that wire into
place and now I'm going to pull these
wires back so I can work on this wire
and just strip off the sheathing
in case you're wondering this is a 10-2
wire we got two conductors the white the
black and then we got a ground and now
we're going to make these connections
I'm now going to use a pair of wire
strippers and use the 10 on the bottom
of the mouth in order to strip off the
sheathing and I usually take off about a
half inch in order to make the
connection
I'm first going to hook my ground wire
to this green screw in order to do so
I'm going to snip a little bit of the
length off because we don't need all
that length to do this so I'm going to
snip it here after cutting that I'm
going to cut this copper wire to length
so before I do that I'm going to go
ahead and kind of wrap it around that
screw so I know how long it needs to be
and it looks about something like so so
I'm going to snip it back to about right
here
I'm not going to wrap this ground wire
around that screw in order to make the
connection so to order to do so we're
just going to wrap it like so
now after I got a nice loop around the
screw I'm just going to tighten this
down to secure it into place
I am going to place black electrical
tape around this white wire because it
is acting as a hot just so everyone's
aware so the first thing I'm going to do
is Twist together these two black wires
like so and I'm going to use my linemans
to do that because I want to make sure I
got a great connection here
I'm now going to take a red wire nut and
twist over that connection and for a
little extra security I'm going to take
electrical tape and wrap around that
connection
and I'm now going to do the same to
these two wires the White and the red is
going to go together in this case
now I'm going to take my red wire nut
and connect those two wires
and I'm also going to wrap electrical
tape around this connection
foreign
the wires inside of this junction box
now that you got all your wires
connected and have them placed neatly
inside of the junction box it's time to
remove this screw and place this cover
over the junction box
I have my electrical and plumbing
connections made I'm going to take
electrical tape and wrap it around this
wire to this water line in order to give
it a nice finished look
I now got to address this temperature
pressure release valve and the reason
why these are on hot water tanks is if
there's ever any buildup of pressure
it's going to come out this release
valve so it's very important that you
route this water out somewhere that's
not going to go all over your room in
order to Route the water away from the
walls and down to the pan I got to
install this pipe and it already comes
with a threaded connection so I can just
thread it right into that pressure
release valve so the easiest way to do
it is turn it upside down and place it
onto the pan and then I'm going to come
down about an inch from that pressure
release valve and then cut it off right
there
in order to make the connection to the
hot water tank I'm just going to place
Teflon tape around the threaded end of
the pipe
now just going to hand tighten this into
that pressure release valve and then
after I have it hand tightened all the
way I'm just going to take a pipe wrench
just to give it a few extra turns just
to add some security to it now that the
hot water tank is installed and all the
connections are made it's very very very
important that you turn the water on and
let your hot water tank fill up with
water before powering on the electric to
it because if you turn the power on
before this fills up with water it's
going to burn up the elements inside of
your hot water tank and you'll have to
replace them so you definitely don't
want to do that and when you do turn the
water onto your hot water tank be sure
to open up the hot side of the spigots
in your house like the kitchen sink and
the bathroom sinks so that way it pushes
all the air out of the tank and it's
going to allow room to fill up with
water so if you don't do that it won't
fill up with water properly as far as
troubleshooting your hot water tank if
you have lukewarm water in your house
the first thing to try is to check the
thermostat inside of the hot water tank
it's usually in one of these covers the
upper lower one and that's going to give
you a place to adjust the temperature in
which the elements are going to heat up
or if it isn't that and your temperature
set and it's still lukewarm nine times
out of 10 it's going to be one of the
elements are bad either the upper or
lower one usually the lower one will go
bad before the upper one because of the
sediment in some people's water so
that's just something to look out for
and also if you turn on there's no hot
water at all there's it's either you
didn't kick your breaker on or both of
your elements are bad so you can
troubleshoot those couple things and
also I want to let you know how to drain
one of these tanks if you take a look at
the bottom here this is a hose bib you
would hook a water hose up to this and
then crack this valve and then it's
going to allow water to come out of the
hot water tank and when you do that be
sure to cut the water off up here or
you're just going to keep running water
out of the house and then once once it's
emptied out then you can take out your
hot water tank for servicing or to
replace it and also this is the water
tube that installed for the pressure
release valve now after I install the
three quarter inch pipe covers in the
back here to give it a nice cosmetic
finish this hot water tank installation
is complete and if you want to know how
a rough Plumb this house with PEX pipe
