My closed couple toilet has been leaking for sometime,(mop bucket needs emptying every few weeks) my boyfriend tried to patch it over with silicon seal.that didn't work. I think it's the seal inside the tank by the syphon that needs replaced. The thing is I can't get the valve to turn off. Though there is a ''tap'' above our front door. Its brass. Would that be the mains.and if you think of any other reason it might be leaking/solution as we live on the top floor.
Any suggestions please
Thanks. Have a good one

OK.well you know how the tank/cistern sits on the toilet, how the seat curves up and toes into the cistern, its dripping from there.but I mean there is silliacone seal all over the joint between them.
I live in a onebedroom flat.3rd floor the bathroom is opposite the front door

Thanks very much, I have one more thing to ask. I want to get this done right so Id like to know where he flappers are, what do they look like, do you have a picture(if possible) The toilet tank doest rock, butwhen I sit on it it definitely leaks more. I just want to make sure that I get it done right
Thank you
:)

Can you tell us where the toilet leaks specifically. Is it leaking at the floor or is the tank leaking into the bowl or the supply line leaking. Where do you live, most mains are located below grade usually in a basement.

What's leaking is called the flush valve and if you can rock the tank back and forth the tank bolts, located in the tank next to the flapper, need to be snugged up to stop the leak. Do not overtighten them, just snug them up to the point of allowing the tank to rock back 1/4". Now see if the leak doesn't go away. Regards, Tom

Tom's advise is the right fix for your proble. When I asked where you live I was wondering what conutry not where the toilet was located in the home.

The Bull's Eye Flapper (500) costs a bit more, but it's very much worth it:
Fluidmaster | The Most Popular Name in Toilet Care (http://www.fluidmaster.com/usa.html) and use the menu bar to navigate to the flush section.

It has a rigid frame that seems to align the plug better. The portion that is made of rubber seems to hold up longer, although durability might depend on your local water chemistry. Mine last at least four times as long as one of the cheap flappers. The less expensive ones are all rubber and may lack the removable adapter that allows the Bull's Eye to be attached to an overflow tube that lacks the pivot pins.

If you ever need to replace the fill valve, the Fluidmaster 400A Anti-Siphon fill valve lasts long and works well too. It fills at full speed until the tank is completely full instead of the faint annoying (and expensive) flow that occurs when the flapper starts leaking. Mine went ten years before it finally needed a replacement 242 Fill Valve Seal .

You asked what a flapper looked like. A flapper is the rubber gismo that's hooked to t5he flush lever with a chain and let s the water out of the tank when you flush. To install you must cut the ring off on the lines provided. Install the flapper on the hooks and not on the ring that sliders over the white overflow tube. Good luck, Tom
