Toilet Flush Button Stuck

[ShaunCorbs]

Remove the old one from the valve totally

find one that will fit where the old one was put the one that fits into a cup of water for 5 mins

after 5 mins put the fibre washer on the valve and install the fill valve and carry on

Thanks so much for your help. I've put the washer to soak now. IS it absolutely paramount I remove all the old silicon? some of it is really difficult to get off especially around the main outlet hole in the cistern.

 

[ShaunCorbs]

Yes get as much as you can off

Ok I've fitted everything except for the lid and buttons and checked for leaks, I think I've got everything tight enough now as I can't see any drips now.
I've turned the water back on but the water level just keeps rising until it reaches the overflow pipe and flows down the back of the toilet bowl. Basically it doesn't stop filling, I assume I need to do something with the fill valve. I'll have another look at the instructions.

 

[ShaunCorbs]

Does it stop if you raise the float?

And does the float move freely ?

 

[andytbker]

The float moves freely but no matter where I move it to the water continues to flow in.
I've made a short video of it and uploaded so you can stream it online: https://mtbker.b-cdn.net/toilet.mp4
I've tried adjusting the height/length of the float with the adjuster but it hasn't helped.

Would say it’s faulty then

worth a punt cleaning the washer just in case anything is keeping it open

 

[andytbker]

You were right the valve needed flushing out, there was small bits of grit in the valve!!. After cleaning out the valve worked perfectly.
The slight problem I've got now is whoever installed the toilet pan/bowl put it slightly too close to the wall so when I flush I'm getting a leak because the 2 plastic bolts holding the cistern down onto the bowl are at a slight angle sigh Its probably why they put so much silicon on, gggrrrrrr!

 

[ShaunCorbs]

Did you replace the donut washer and bolts ?

Did you replace the donut washer and bolts ?

Yep but only did them hand tight, theres no leak from the water just sat in the cistern only when I flush. Also I cant get the lid back on properly as the back of the cistern is at a very slight angle. Looks like I'm gonna have to dis-assemble it all re-align/retighten. I've had enough for today so will have to look at that another time.

 

[ShaunCorbs]

Is it a rubber donut or foam

 

[andytbker]

Is it a rubber donut or foam

Rubber doughnut, my toilet has a 2 1/4" hole so the instructions said remove the seal already on the threaded shaft and fit the rubber doughnut which I did.

 

[ShaunCorbs]

No the one between the toilet pan and cistern ?

 

[ShaunCorbs]

Eg like this top right rubber

Ah right, so theres supposed a rubber doughnut on the flush valve steam (which theres is) AND on the underside of the pan where the locknut is? I didnt replace the original one that was there.

 

[ShaunCorbs]

Correct you have the one that seals the flush /siphon to the cistern but your missing the one between the pan and cistern

Can I just use the original rubber doughnut?

 

[ShaunCorbs]

Yes aslong as it’s not damaged or misshaped

 

[andytbker]

Got another problem now, I've disassembled the toilet again. When I put the old rubber doughnut over the new lock nut its loose and I don't think it should be like. Basically the diameter of the hole in the doughnut is much bigger than the diameter of the locknut. The old lock nut was a bigger diametere but will not fit on the new flush valve thread.
Does this mean I need a new rubber doughnut of a different size? The kit came with one but it said use that on the upper side of the thread because I have a 2 1/4" outlet.
I've attached photos of old doughnut and new locknut. Also my toilet didn't have those metal brackets that come in those doughnut kits.

 

[ShaunCorbs]

If you can put the old one on the toilet centre it as best you can in the hole if you have any silicon grease or vaseline you can use a small amount to stop it moving around

then to the best of your ability centre the cistern over the hole and slowly lower it down onto the toilet being careful not to move the washer too much and then tighten the bolts up

try that might work if not you need a new foam or rubber donut

 

[andytbker]

Now I can't get the inlet valve to thread onto the bottom of the fill valve, I did it before so not sure whats going on. Will just have to keep trying.

 

[ShaunCorbs]

Be careful not to cross thread the valve
