Vitra dual flush running constantly....Help?

[Mick590]

Hi,

Can anyone advise me on how to stop my dual-flush Vitra toilet running constantly?
Firstly, how do I open the cistern lid?
The toilet was fitted in our new house in late 2007.
Any help greatly appreciated. I have isolated the in-line valve & flushed the cistern.

The push button should screw of, when that is of you can just lift the lid of, you may need a new ball valve as I suspect the water level is getting to high and is going through the overflow and will cause the water constantly running into the pan

Hi Mr M,

Unscrew the outer ring?

 

[MrMeek]

yes the push button in the picture it should just screw of if not, you need to prise the buttons out of the ring and there will be a screw under it, try just screwing it of first though

Hi,

Got the lid off....thanks Mr M.

The water is still trickling into the bowl.

The noise I've been hearing is like a release of bubbles, it happens now when I push the float to the left of this photo.

The water level never seems to reach the overflow tube on the right?

 

[MrMeek]

its the ball valve, go to plumb centre etc and buy a fluid master brass shanked fill valve, best you can get for instructions on how to change the valve watch this video any problems reply to this thread, and watch the video first : How to install a toilet water inlet valve - Torbeck valve - Ultimate Handyman DIY tips - YouTube

Thanks Mr M,

Hopefully will return only to say thanks ;-)

Happy New Year

Have you tried adjusting the height of the float to lower the water level in the cistern?
The white plastic rod with a cross on the end - turn it (closkwise I think) to adjust the height of the float about a centimeter lower than it is now. If that doesn't fix it, then yes, replace with a quality brand like fluidmaster.

I think you will find it will be the seating washer on the flush section being gunked up
not sure if your one will allow but most twist about a quarter turn and lift out to expose seating washer for you to check/clean ....water will continue to fill as level cannot be reached untill you stop water passing by the seating washer hope this helps regards turnpin

would of advised that but the valve is one of them crappy ones you get with b and q toilets, better doing what I said and get the best one on the market no more problems

 

[Mick590]

Mr M, Turpin,

Is the seating valve on the other component?

I had to but the same ball valve mech that is fitted, short on time & work o'sees.

Will fit tomorrow & see

Cheers, for all the input guys, hopefully have a dribble free new year ;-)

better doing what turnpin says, flush valve is passing, you may need a new one, probs nothing wrong with your float valve.

I have just re read over this thread and didnt see that you said before that the water is not reaching the overflow, just read the bit about bubbles from the ball valve, Turpin is most likely right, the "other part" may have something stopping to fully sealing, the other bit should just twist and pull out clean it up and clean up the part what is left in the cistern put it back in and see if this solves it.

sorry for any inconvenience

 

[Mick590]

No probs,

Not unboxed the float valve yet.
Will have a play tomorrow & see how I get on.
I have spent many an hour replacing parts on aircraft only to find it still not working, usually because of a simple fault we dismiss!!

Many thanks for all the inputs.

Over n out for now ;-)

Hi Mick590 yes the sealing washer is under the other component the flush valve good luck regards turnpin

I thought you meant there was a seperate overflow out of picture on the right. If you mean it is passing without reaching either a seperate overflow - or the integral overflow in the flush valve then 'oops'...

 

[Mick590]

No mate, the tube in the original picture I presume is the overflow into the bowl?

Yep that's it. and it must be kaput as mentioned previously. Looks relatively clean in your cistern but who knows, it may need just cleaning or replacing as mentioned above.

 

[Mick590]

:banghead: OK, what can it be?


I've replaced this complete unit & it's still running into the pan!!!
The area on the base of the cistern seems damage free & clean.

Help!!!!

 

[Mick590]

Have taken the flush mech out now, is a bead of silicone a good idea or not?

 

[MrMeek]

question, does water still run into the pan when the lid is of?

edit- use plumbers gold its better but yes silicone will do the job but you will have to leave it for a few hours to set

 

[MrMeek]

3 things what I can think of whats the problem:

ball valve is letting to much water in and its going through the over flow but you said this was not the case
flush valve is broke but you said you replaced it
next thing I would do is take the lid of and see if its still running if not post back please

 

[Mick590]

Hi,
Ball valve does not keep filling, water stops well below o'flow
Flush valve old & new seem in perfect order. Cleaned old seal before I bought & installed new valve assembly.

When water is isolated, flush toilet and leave........the cistern totally empties which leads me to believe it's getting past the flush valve to cistern seal?

 

[MrMeek]

theres no cracks in the cistern is there?

 

[Mick590]

Can't see any mate, gonna let it dry out completely then see.
Will silicone do the trick or not?

Was looking at putting a layer all around the area then fitting the valve stack.

I would use plumbers gold, put a thick bead around the "black ring" you can use silicone but it doesnt seal instantly.

did you replace with complete new unit or take out and replace?

regards turnpin

my thinking was the flush valve, if not dirt, some develop air bubbles and constantly dribble

 

[Mick590]

OK mate,

Will look tomorrow & get some.

Will post the results tomorrow...........

Cheers for the help,

Hi,

I took the old unit out & cleaned all the seals first then re-installed it.........no fix!!
Bought new unit, set up identical to old unit & still the trickle!!!

Must be a problem around the outlet hole, will try plumbers gold as suggested, then maybe a hammer ;-)

 

[JCplumb]

Without being there it's really difficult to diagnose.
Given what you have said about the cistern totally emptying after flushing it must either be the top seal on the flush connection or the bottom seal in the flush mechanism. You could easily diagnose which if you take the cistern off but leave the flush mechanism in place then put it over your bath and pour some water in it. Look from below to see where the water is passing. If it's dribbling down the threaded part then it's the seal between the valve and the cistern base, if it's dribbling down the inside of the pipe then it's the mechanism.
If it turns out to be the mechanism then take it back to the shop for a refund and get down to a screwfix for a fluidmaster button operated syphon - that is of course if a fluidmaster will fit in there, best to measure first...

Well,

Could not find plumbers gold, so bought some Evo Stick "sticks like sh*t"
Put a bead around the hole & screwed the flush assy in & it seems to have dome the trick!

Thanks for all the advice on here

Mick
