this is a very
common type of tap this one's actually
started leaking it's actually dripping
from the spout where it's actually
dripping down the side
and down the back is it what happened
it's actually stopped doing it now since
i tightened the top up because the tap
was actually loose
but it's not going to stay out for long
it won't be long before it starts
dripping again
it's actually filling the unit below
with water
so we're going to change the cartridge
in this tab new cartridge
looks like that's
so you've simply got a ceiling ring at
the bottom
and then you've got the lever on the top
so these are normally very
easy to change they're not cheap that
one was
nine pounds when you compare that to the
price of an actual tap washer these
do work out quite expensive we're going
to start off by
putting the plug in and then nothing can
get lost down there
then we're going to take a pair of
pliers and we're going to pull out that
part
just there that is indicated that
indicates
which side the else in the cold is
so i've now removed that small piece and
you will notice there's a small rubber
piece still in there
we can grab that with a pair of pliers
and pull that out
like so it can be difficult getting the
actual lever off these taps
because what happens is you tend to get
a build up of lime scale etc
which tends to fuse it onto the actual
lever so that plastic part there the
metal bit actually slides on that
i do have a scrap one here and you can
see that there is considerable
pitting and corrosion in there and what
tends to happen is that tends to get
stuck
in there so it can be difficult getting
that part of the lever off
the actual cartridge before we go any
further we're going to isolate the water
which as you can see is now being
switched off we're not going to get a
torch
we're going to shine that into that hole
sometimes these are a slotted screw and
sometimes they are an x key
and if you look through there you can
just see that this one is actually an
x key so we're not going to feel in
there until we find
the grub screw
and then we're going to undo that
i've actually just lost that inside the
top for the minute we're not going to
get all of the handle and pull it up
these can be quite difficult to get off
so we're just going to give it a spray
in there using some wd-40 on the straw
and that is actually coming but it is
very difficult because it is very tight
and eventually it will come off like so
as you can see that is actually full of
water
so i'm just going to recover the glove
screw
then if i put him back in later on
we now need to remove the shroud that
can be incredibly difficult to remove
without damaging it
so to remove that we're going to use a
strap wrench
these are very useful pieces of
equipment and these can be used to
remove things like this without actually
putting any tea marks on them
or anything like that so if you've never
used one of these before
it actually has a narrow one which shows
the direction which it needs to be
pulled in
so we're going to hook that around the
shroud
and we're going to push it on
and then we're going to try and undo it
using that
and we can't actually undo that at this
moment in time
so i'm just going to put some tissue in
there
and try and soak up all of the water
and then i'm going to give that a spray
with some spare penetrant
and i'm just going to leave that to soak
in for 10 minutes or so
we're now going to take the strap wrench
again
you can see that that has now undone the
shroud
so that is the difficult part
in fact that is very unusual we've
actually removed the shroud
and the nut normally those two
components are separate and normally you
remove
the shroud first and then remove the nut
so we can now pull the cylinder out
if you look at that you can see that's
got some white bits on it
it's not supposed to be like that it's
supposed to be all blue
so that seal is probably the bit that is
causing the problem
we're not going to put the new cartridge
in position it is important you get this
the correct way around
it is pretty easy to do because of those
two lugs
which meets up with two holes that are
drilled into the actual tab
so we know that it definitely fits that
way around so we can now just push that
in until it goes into the
two locating looks now that we've
separated these two components it will
be a lot easier
to stop this part from every seizing up
again i'm going to apply some silicone
grease to it
this is suitable for use on possible
water just in case
so that has now got a good quartinger
silicone grease on it
we can now carefully screw that back
down
when you do this you need to make sure
that you do not get it cross-threaded
you can see that that is screwing in
there very easily
now we can simply take a suitable sized
spanner
and then we can just tighten up that nut
you don't need to go crazy when you're
doing this it just needs to be tight it
doesn't need to be
really tight all you're doing is
compressing
the ceiling ring at the bottom
we can now refit the shroud you don't
need any tool to do this at all
simply put it on ensuring it's not cross
threaded and then just tighten that up
by hand
it's now a good idea to turn the water
back on just to ensure that you have
done it correctly before you actually
put the lever back
on the tab i have now turned the water
back on but i've only just cracked the
stop tap
open just enough so that we can actually
test
it and you can see that the water is
coming out of there
and we have no leaks so now we know that
that is not leaking anymore
we can now go and open the stop tap a
little bit more
i have now cleaned out in there using a
square file
and i'm just going to apply a little bit
of grease
to that part and then hopefully
next time when somebody comes to service
this
it won't be quite as difficult to do i'm
also going to apply a bit of silicone
grease to the grub screw
and then we can start that in the lever
before we put it back on
so i can now push that back on
and then we can tighten up the gloves
through
i can now test the top
so the boss is working perfectly
that is the call now all we need to do
is take the
rubber parts that came out earlier push
that back
in the hole
and then push the collar indicator back
in
obviously the red goes to the left hand
side
so that's how to change the cartridge in
a top like this
it is normally very simple but you can
come across
a few problems which i have demonstrated
so i hope that's been a useful video
and if you haven't already please
subscribe
i want to give it a really good spray
now with some stray penetrant
in the hope that it breaks the seal
between the two components
i'm not just going to leave that for
about 15-20 minutes and then i'll come
back and have a go at separating the two
components
and i'm just going to take it and i'm
going to drop it into some boiling hot
water
so we're just going to leave that in
there a few minutes that might help to
break the bond
between the two components
now emptied most of the water out i'm
just going to fish that out here glove
on
and we don't get burnt
you can now grip the nut with some paper
towel and successfully undo that
before we put these back we're just
going to give them a clean so i'm just
going to wire brush that
