Hello and welcome to this video about how to change a faulty fixed central push button flush unit.
In this video were going to use a FlushKING fast fix repair kit. I hope you enjoy it.
The first thing we need to do is find the water supply.
and that's just in here and turn that off.
Once we've turned the water off we need to gain access to the inside of the cistern
A lot of top fixed push button units need their button popped off and then there will be a screw under there that you can undo.
This has a flexi underneath it so you can just lift it off.
but sometimes you can lift the cistern lid off and find you can unscrew and remove the button from underneath.
and as you can see this is the type we can un-screw and remove from underneath.
now that we've got the lid off the cistern and we've removed the old button, what we need to do is get
the water out of the cistern
As you can see now we've flushed it
there's also a small amount of water in the bottom so we're still gonna have to
towel that out as well.
Now that we've got the water turned off and the cistern is empty, we have to go about trying to remove
the cistern from the toilet itself.
Most cisterns have two screws at the back that go into the wall,
and then two butterfly screws at the bottom that hold the cistern on.
What we are going to do now is get those removed, we're going to lay a towel on top of the toilet then
so we can lay the cistern on top of it and work on it.
This type of toilet has bottom screws that go through the top of the cistern and through the toilet.
then there is a screw and a nut that clamp up together, make sure you get a nice long slotted
screwdriver, and pop that down onto the slot at the top of this nut here
and get your hand down underneath and undo the nut. If you've got the different clamp type you have to remove the two wing
nuts on the bottom and then the cistern will be able to come off.
Once we've got these two screws off and the two bottom screws off, all we need to do is disconnect
the water supply and then we can lift the cistern off
and lay it on top of our toilet.
We get a towel on here..... and lay the cistern on there.
Now its the easy bit, undo this nut on here, what we need to do is get a large pair of grips
give this a twist and loosen it off, you should be able to undo that with your hands.and then, come round this side, you can easily pull out the old flush unit and throw that away.
now is a good time to check the condition of the doughnut, that's just sit there and will seal up around the bottom of our cistern.
also if you've got the different type of clamp where you have the metal clamp that goes around here and the wing nuts on the bottom
You might also want to think about changing that now.
Right, so were now going to un-box our new unit, we've got our new button with adjustable legs that push down.
On the flush unit paddles here, on the bottom of the flush unit we've got a new rubber washer, we've got a sealing nut.
to tighten that up onto the bottom of the cistern, we've also got another rubber seal that we
can change for this one here for a different size cistern outlet.
So, all we need to do is, spin round our toilet and we insert it so our automatic overflow
is the opposite side of the cistern to the fill valve.
Now you may notice here that our thread kind of hovers in the middle of this larger hole.
That's why we can replace this washer here, and pop this one on for a much better fit.
as you can say that's a much better fit
Now, we can pop on our nut, tighten that up by hand and give it a little nip up with your grips.
but don't over tighten it, remember, there's a really large, very thick rubber washer there so it will only need a slight tighten and that should
easily create a water tight seal.
Once you've got this bit done its a good idea to make sure these two nuts are still nice and tight.
Obviously if you've got the clamp version these two wont be there, but right now its a great idea.
If you find you've got a problem with these two nuts FlushKING also produce a little repair pack for those.
And now, we can lift it back into position
Make sure when you do this that the sealing doughnut doesn't move out of place.
Now we've got the toilet back in position we can redo our two bottom nuts, re-tighten them up.
We can re-screw in our two top screws, and also we can reconnect the water supply.
What we do next is adjust the fill on the fill valve, but most importantly we adjust the amount of water that comes through
on the half and full flush.
If you look closely on the side of the flush unit itself, there are two sliding scales,
One called half, and one called full. Usually I will set both of them in the middle and all that does
is determine how much water is released from the cistern when you press either a half or full flush.
After a couple of days you might think one or the other isn't adequate
and it's very easy to move the dipper up or down with a plus or minus sign
to get the flush that you require.
Then I will just twist this round, back into this position ready for our buttons.
setting up our button couldn't be easier, just get the old lid, remove the packaging from the button.
Take off the nut, make sure that your full and half flush buttons line up with the dippers on the top of the flush unit.
Once you've done that, pop your screw over and do that up
The great thing about these two plungers is that they can be removed and you can cut theses two threads down to size.
You have seen how easy it was to get that in, all I have to do now is turn the water on, test the flushing capability
and also test the leaks
Great lets pop this on and have a look.
I've now given the toilet a few flushes and there's no problems, I'm just adjusting the flush to how I want it.
You now don't even have to worry about having an external overflow because these flush units have it built in.
if this valve fails, the water will go into the internal overflow and flow down the toilet, letting you know that there's a problem.
So there we go, we've quickly changed over our flush unit for a fixed top button flush unit
We've adjusted the buttons, we've adjusted the flush, we're going to save more money now and also we've got our integral overflow
as well which makes the cistern a load more safer.
I hope you've enjoyed this instructional video and you've learnt something, and thanks very much for watching, goodbye.
