My toilet keeps running after I flush it. When I open the cistern, I can see the flap is stuck in the upright position. I have taken the flap off and cleaned it in the hope that it just got stuck up because it was dirty, but this doesn't seem to help. It would seem if the flap was heavier it would close - other than gluing a penny to the flap does anyone have any suggestions please! Thanks Britami

 

Britami,

First, you need to determine why the flapper valve is not going down. Most probable cause is not enough slack in the chain connecting flush handle with flapper, next most probable is the chain is hanging on the float arm or something else. Find out what is keeping the flapper valve from closing and you will solve your problem.

DO NOT PUT A PENNY, or anything else on top of the flapper valve. There are 114,587,589 toilets functioning properly right now, without a penny on the flapper valve <ggggggg>.

BTW, most people refer to your cistern as the toilet tank.

 

Thanks for the suggestions Rick - but the chain is long enough and does not get caught on anything. It really is just a case of putting more weight on the flapper (normally my finger as it runs every time I flush it)and it then closes. And I guess my english background makes me call it a cistern (not sure of the spelling) rather than a toilet tank - but thanks for the tip - hleps me to be clear in the future! Britami

 

Clean the rim of the flapper seat, and replace the flapper.
Good Luck!

 

Try a new flapper %99 of the time this will solve it.
