Hi there, and welcome to this brief instructional video on how we change over
an old lever type flush to a new push button, dual flush unit.
I hope enjoy it. Right so the first thing we need to do is turn off the water supply, we're very lucky because we've got a nice
little shut off valve just here.
now, we pop the lid off the toilet
and pop that to one side, and flush the loo. Try and really get as much water out
as you possibly can. In the bottom of the cistern now you should have about an inch of water.
what we need to do is just get a towel and towel all of that out into the loo.
do that for as long as he can.
Get as much of the water out as possible.
Once you've completely emptied the cistern you will usually find there are two screws
that hold the cistern back to the wall, get yourself a screwdriver and undo those now.
Now we remove the old handle assembly. This is usually held by a
back nut on the back to hold the handle nice and tight to the toilet cistern.
and to attach the handle to the flushing mechanism you usually have a screw just here.
Once you've removed the screw, you should be able to wiggle off the arm.
then unscrew the nut and remove the old handle
now this is the tricky bit, because we've got here a close coupled cistern
underneath here we have a clamp with two wing nuts, what you need to do is get underneath the toilet
take off both of those wing nuts, by unwinding them, you might need some sort of lubricant to do this.
if they have been on for a while, and keep those wing nuts and washers to one side.
sometimes if you're unlucky you might have to cut them off and replace the bolts.
Once you've either cut off or nicely removed the wing nuts, all you need to do is
slacken off and remove the water supply that you valved off earlier
do that using a set of grips and a pair of adjustables.
there we've got those done, just lay down a couple of bits of cloth, you should just be able to lift your toilet
off here. If there is still any water in the bottom of the cistern now, now is
a good time to pick it up and pour it down either the bath or a sink or the toilet.
So now we are at the mucky end of the job, what I'm gonna do is just remove
each one of these screws, and remove the one that we cut a minute ago cos were going to replace that in a minute.
Now that we've got those two screws off we're going to just slacken off this nut here and we're going
to keep the doughnut
attached to its metal clamp...... Now it should
just lift this clamp off nice and gently without damaging the doughnut, pop this to one side.
Now we should easily be able to remove the old flush unit, and there we go there's our old
ancient flush unit out of the way, you can now throw this away.
So then, now we unpack our new flush unit.
We've got a washer here that if the hole on the outlet here is bigger,this will actually convert
our washer so it will fit in different size cistern holes. We've got
our button, nice push button, we've got our flexible cord that goes to the button.
and then we've got our flush unit itself, on here we've got a nice new nut
and a lovely new rubber washer at the bottom, we've also got an integral overflow built
in, so if the water level rises too high due to a failed valve
the water will flow down here and into the toilet, thus eliminating the need for a
an external overflow outside of the house.
You've also got a really innovative way of gauging how much water comes out when you want to do a flush
this is for the half flush here, usually what I will do is I will set that to five,
and then on the other side we've got our full flush here, and what I will usually do is
set that to around three. They're just easy to do just push them in
and then after you've installed the toilet for a little while you can move these about easily from
above to get the type of flush that you desire.
What we need to do now is, we will install our flush unit
so the overflow is the opposite side to the fill valve here.
So if you watch carefully now that's how I'm doing it. So we'll just pop that in
Make sure our rubber washer is already on and nicely seated, make sure very quickly
that the seat on the inside that the rubber is going to sit on is nice and clean, pop that in like so,
now we get our doughnut and metal washer that we put to one side
pop that back in, and then pop our new nut on. All you need to do
is grab yourself a pair of grips and just tighten that up a little bit, doesn't need to be a lot.
Now we've got that tightened up I'm just going to pop my two new bolts in here. Now were ready to pop the cistern
back onto the toilet.
Make sure that your screws line up with your holes
once you've got your cistern back on the wall,
you can go about re-doing up your wing nuts on the bottom, making sure that they are equally done up
so you get a nice seal on the bottom.
you can then put your two screws back in a the top, and lastly
re-attach your water supply. Now before we continue much further
make sure that the ball valve or any fill valves aren't hindered by the
new flush unit you've installed. The next thing we need to do
is remove the packaging from the button and remove that from the mecanism using the small clip
then you can remove the nut from the button and actually attach the button itself to the front of your
cistern.
Once you have done that you can pop the mechanism back on
turn the water back on and watch the cistern fill up. Right then, so we've got everything ready, we've got our button on here
Now we can test the flush and make sure we've got no leaks.
Here we go...... Great, so there we go we've got no problems, now all we need to do is
pop our lid on, give everything a wipe down and a clean,
and were done. You can also change your old type lever valve syphon unit like this
one we've got in here,
to a modern dual flush valve here that has half and full flush
and uses the same technology as the push button flush inside here.
Simply lift up for a half a flush and down
for a full flush. I hope you have enjoyed this video
thanks very much for watching. Bye Bye
