Toilet flush running on

[rjm2k]

Our loo keeps running on after flushing, I've altered the height of the fill float as much as possible but it still continues.

I can't see anyway of adjusting the syphon float, is there one? Is there a seal or something to replace or am I better off just replacing the whole lot with something like this?

Thanks

If the water is actually running over and down the central tube, then the Torbeck float is adjustable to some degree, but on most models the whole fill valve is telescopic.
If the water level is below the central tube, then its the seal at the bottom that has given up.

I think the level is above the base of the blue part (just above the white tube it's in) so I'll have a go at working out how to adjust the flush float.
Thanks

is the cistern filling up ? or just a shallow pool at the bottom?

 

[rjm2k]

it's filling up, goes just over the white pipe in the syphon

if its filling up and overflowing down the centre of the siphon then your torbeck valve has failed, you can change the ''gubbings'' easily enough, but inho from experience id change the whole thing, cheap enough to buy a replacement

yeah thanks, I'll probably get one of the fluidmasters I posted a link to, I assume they have the inbuilt overflow too?

providing your toilet is flushing fine, you dont need a new siphon, just a new fill valve, (valve on the left)

ok ta, might just take the opportunity to renew the lot though

you will most likely have to remove the cistern from the toilet to change the siphon, to change the fill valve you dont

Update on this, we've had visitors for a while so not been able to do anything until last night when I isolated the loo water supply. Today the cistern is completely empty and the loo has not been used so I'm guessing it's the syphon that's at fault rather than the flush?

you should be able to twist the syphon to remove it & just leave the bottom part in the cistern (leaving the cistern in postion on the pan) & check the washer at the bottom to see if it's split or has some crap on it

The syphon IS the flush.

If the cistern was empty yesterday then we've gone from too much water (overflowing) to too little (empty).
Confused!

I think the inlet valve must have been running because the bit in the middle of the cistern (the syphon?) is letting water out, hence once the supply of water was cut off it all drained out.

I'm sure I'll sort it even if I end up replacing both.

Thanks
