in this video I'm going to replace this single basin mixer tap this can
be very difficult to do because it is difficult getting access because the
basin is actually in a vanity unit so that is the tap and as you can see the
water is leaking quite badly down the side of it there and then it is actually
leaking and pooling all the way around the basin this tap also has a pop-up
waste at the back there so we will have to ensure that we fix that on to the
new tap it is very difficult tightening and undoing the nuts which hold the
taps in position but you can make it a lot easier by getting a box spanner like that
you can actually buy a set of these and these actually go from about 9 mil up to
13 mil and you can see that that's a good fit on there and then on this end
I actually get a socket that will fit that end and then I can use the ratchet to
tighten and undo the nuts on the tap that we are installing it actually has
two nuts that need tightening and the one that we are undoing only as the one
nut which is holding the tap in position this is going to be very
difficult to film because of the restricted access underneath I've now
been downstairs I've isolated the water and I've opened the downstairs tap in
the central position like that so it's actually drained the hot and the cold
water so now on this one if actually open that up you'll hear that making a
noise that is the water draining out of this tap and that will be going
downstairs if you have a conventional heating system you may need to close
a gate valve on the hot water side you can actually put a new cartridge in
these taps but a lot of the time it's not really worth it you're better off
just fitting a new tap as you can see that the top on this one is all corroded
and that is where these zinc is actually corroding
so after a few more years that would be so badly pitted that it would look
really bad. in order to make it easy I'm just going to disconnect the pop-up
waste I can that can do that simply by undoing that small screw so I've rigged up the
Box spanner and the ratchet and we're now going to undo the nut which holds the
tap in position as you can see the whole stud has actually been removed from
the tap there we can now just grip the compression fitting with a pair of water
pump pliers and then we can undo the nut on the top there that's the horse shoe
that has just fallen down as you can see that is in pretty bad condition we
can now simply lift up the tap and you can pull the flexi's through the hole
let's give that a clean with a multi surface wipe so I'm gonna take the new
tap and in there we put this O ring which is called an anti-rotational
washer in the instructions we then take the two tails and screw those in and it
does say in quite a few places that you should not use a spanner to tighten
these up, so you only need to screw these in by hand they are both now tight
we also need to put the two studs in they simply screw in the back like so
I'm just going to nip those up with a screwdriver we can pop the waste through
there the waste on this tap is actually in two pieces so we're just going to
push that through there for now and then we'll connect up the other side later
so we can now take that we can push the hoses through the hole at once
and then from underneath we need to put the rubber washer on with the metal
horseshoe washer and then we need to put the two nuts on and that will hold the
tap in position at this point you need to ensure that the tap is perfectly
straight and finally we're just going to tighten those up using the ratchet
obviously you don't need to go mad when you're doing this you don't want to
start breaking anything we can now reconnect the flexi tails ensuring
we get them the correct way around obviously the cold one is on the right
unfortunately the new flexi's are a little bit shorter than the ones that I
took off with only about an inch shorter but that means that this is very taut
which is no good so what I'm going to do is I'm going to swap this part for an
isolation valve like so that will give us a little bit extra height and then in
the top of that I'm going to put a flexi tap tail adapter so this is a little
bit of extra work but it's one of those things that you really need to do
because you do not want a flexi tail like being taut because it can lead to it
failing
because this one's more difficult to get to I'm going to put the Flexi tail adapter in
there there is a copper olive in the top obviously, I'm now going to tighten that
compression nut and obviously we're going to ensure that that is very tight
once that's tightened in there we can then get the Flexi Tail, we can screw
that directly onto the adapter ensuring it's not cross threaded, we can just
type that up using a spanner obviously we don't want to go mad when we're
doing that because it is only a rubber sealing washer in there you do need
to ensure when you're fitting the isolation valves that the arrow is
pointing in the correct direction, this time I'm going to make it a bit easier
I'm gonna get the isolation valve put the tail adapter in there and then I'm going to tighten
this up before we put it in position
obviously it's a lot easier now we can just put that in position and tighten up
the bottom compression nut so they are all now really tight we now just need to
screw on the final flexi tail and then finally I'm just going to re-instate the pop-up
waste, unfortunately I can't film this bit because it's absolutely no room
in there whatsoever I've now de-isolated the water and
checked for leaks I'm just going to get piece of kitchen
roll which I'll cut into two pieces I'm just going to wrap that around the pipe
if you do this if you do get a tiny weep it becomes immediately apparent because
the tissue will be soaking wet in no time so you are a lot better off doing
this rather than waiting for the water to come through the ceiling so that's
the new tap you can see the pop-up waste is working when you op the top for the
first time you need to be aware that is going to be air- locked so it's a good idea
just to crack it open very slowly I have actually had this tap open and they
have actually bled all of the air out of the system, I hope you found this
