- [Jeff] Okay, so we're looking here at where
it was leaking here from.
This is one of the older P-traps.
I guess this place was built in the early '70s,
and this is the original P-trap that's still here.
And you can see it's leaking water
and the reason why it's leaking water even when it's off,
these P-traps hold water down here
in the bottom part right here and what their purpose
is is to keep the sewer gases that come in from the street
from getting up into your pipe and you would smell it.
They'd get in through your drain.
So the gasses can't get past the water that sits here.
And neither can the little bugs
that are likely in there too.
We often see bugs whenever we cut a pipe right there.
("Mister Right" by Simon Aimer)
So, what we're gonna have to do is,
see this is sort of an old school type of a P-trap,
'cause they used what we call overkill,
they used the bigger 1 1/2 inch parts to mate up
to the 1 1/2 inch pipe, which is fine,
but see eventually you have to convert to the
1 1/4 inch downspout from the vanity sink there.
And so they did that with a trap adaptor
'cause it's slip fit.
We call that a slip fit, there's no screwing in right there,
that pipe just slides right in there.
So, all of this is gonna come off and we use a different
method now, we use this type of P-trap.
This is a poly pipe and these are cheap,
they're three bucks, easy to get.
And they'll mate up to the bottom.
This right here will mate up to the bottom of the
tailpipe there from the sink.
And then this part will go into the wall.
The only probably is this won't fit directly into that
1 1/2 inch pipe so we have to use this which is a
1 1/2 inch trap adapter they call this.
So, the way this one works is
we have to cut this old one off the pipe,
this will get cemented on,
and then the P-trap tube will just fit
right in there into that slip fit.
Also you'll notice that quite frequently
when you buy new P-traps,
it's gonna be lower than the tailpipe.
So, you're going to have to get an extender.
In fact, you can see here,
originally they built an extender here
but, fortunately with these poly tubes
that we're using here, you can get an extender.
And make sure you get 'em with the green bag
that says 1 1/4 inch.
Because this is going on to 1 1/4 inch tailpipe
in the vanity.
If this was under a kitchen sink, you'd be looking at
1 1/2 inches.
So, we just got a six inch one and hopefully that will be
big enough for us.
So now we have to cut this tailpipe off right here.
The problem there is because we have this brace here
in the middle of the door so it is gonna be hard
to get back in there.
There's two ways we can do this.
We can do it with this PVC pipe cutting saw right here
and we'll see if we have enough mechanical advantage
and enough movement there to make it happen.
And if that doesn't work,
the other tool that I often like to use,
is one of these here, this is a inside PVC pipe cutter.
So, you put this on your drill and it cuts.
Even though this is made to be put down
like inside of a toilet flange and cut around
the inside of the wall.
You can still use this on the outside.
We would probably just try to get it right in around,
right in around back over here.
So, let's see what we can do to get this cut off.
Okay, so we loosened this P-trap adapter here,
and then I've already loosened the part
in the back there, this one here.
And so, make sure you have a bowl below it because
the P-trap is holding water.
That's why they call it a trap, it's trapped the water.
So, you just pour the water out.
So, you always wanna make sure you have a bowl
or a pot or somethin' there to catch all that water.
Or you're going to have a big mess.
So, now the front part of the P-trap is off.
So, now we have to take our saw and just cut
right behind where it was cemented on there.
And slice it off nice and clean.
Okay, so there we got it with the saw.
Got all the way through it, nice and clean cut.
There's your pipe.
Okay so now, here in our state, Florida,
we use white PVC pipe, right?
So, we gotta use this purple primer
before we use the cement.
You have to prime and it's required by code.
So you have to prime on the inside of this part
and then we'll prime over on the outside of that pipe.
And don't think you're gonna get away without doing it
because you'll just have failure down the road.
And believe me folks, I know two people in the past year
who've had failures from PVC pipes that came apart.
One a friend of ours had tens of thousands of dollars
a damage in mold in their house simply because
whoever put together the PVC pipe for the drain
of their air conditioner, leaking to the outside,
it leaked inside of their wall and it caused mold.
And a huge loss for them.
So, you just take the little purple guy there,
rub some around, and there you go.
And we're gonna take some,
we're gonna put some on the pipe too.
You don't need a lot, you just need to cover the area
where they're going to meet.
And make sure you screw these lids back on
with channel locks because they will tip over,
they will leak, these are notorious for leaking.
K, now the key with this cement,
is you only got about 10, 15 seconds to work with it.
So, you quickly brush the inside of this part with it,
then you quickly brush the pipe with it
and then you put the part on there and you twist,
90 degrees, quarter turn, and push in and hold
for about 30 seconds.
If you don't push in and hold, it could force back out,
that's just the pressure of the cement and all that.
But, the guys that don't do that end up getting called back
to repair it the next day.
K, so the new part is now cemented on there.
All we gotta do is cut and fit everything else to fit
on to that tailpipe.
Okay, so as we dry fit this,
the extension tube comes with this nut here
and it comes also with a green washer.
And you always put it on with the flat side
of the washer upward so that this can rest down on it.
And then the tube goes right up in there,
as far up as it can go, you want the tailpipe here
to fit all the way down to the stop.
And then once you got it, you can screw it in.
So, we'll see if we need to cut it or anything
to adjust the length.
It looks like we're going to because if you look here,
see the bottom of the tailpipe here
is gonna be lower than this stop here.
So we are probably going to have to make an adjustment
to that and cut that piece.
Okay, so this part is now tightened
and we have both sides
of the extension tube here are tightened.
Now remember, this was a six inch tube that looks like
it's cut down to about four inches is what we had
to end up doing with it.
And don't forget to put on the slip side of that tube also,
you gotta put the some thing, that green gasket there,
horizontal side up, and this nut goes on first.
So that you can tighten it onto the P-trap.
And you just tighten it around and likewise,
don't forget as I showed you earlier,
the top part of this also has a washer,
there's the green washer, flat side up,
and the nut.
So, now that your P-trap is now installed,
you do a water test, you turn on the water,
(water running)
and the water should flow nicely,
there should not be any leaks.
So, you need to check here,
you need to check here,
you need to check at this spot here,
you need to check where it connects into the drain pipe,
and then you also need to check
way up here under your gasket.
And look for any drops, feel around for any water,
and what I always tell people to do,
is put down my paper towels, this is from the old mess,
and leave them for a few days and that way
if you see any water land on 'em there,
you'll know you still have a leak.
And if you have a leak and you see it's coming
from the bottom of your gasket there underneath
your vanity sink basin, we have another video for that
and I'll put a link to that down on the description.
It will help you deal with that specific issue
there of what happens when you have a leak
coming out of your gasket there.
That's a very common problem especially when people
put in a new drain and a new faucet and everything
and they do everything by the instructions
and they still get a leak coming out of that gasket.
So, we'll put a link to that down
in the instructions for you.
