Hoping someone can help with a little problem I'm having. After flushing, my toilet cistern is very slow to refill. It does refill eventually, but it takes a really long time.
Sometimes after flushing, if I turn the bath taps on and off, the cistern fills up at normal speed, but this doesn't work every time.
This is my cistern with the lid off so you can see what type it is
And this is a valve to the left of my cistern
When the cistern is filling slowly, water trickles from this valve. But when it is filling at normal speed, the water comes from elsewhere. I have to say I'm not sure exactly where is is coming from(how embarrassing!) the best I can make out is it is coming from the bottom of the valve/ballcock arrangement to the left.
Any help for someone who isn't too great with these things (as you'd probably guessed by my descriptions!) is greatly appreciated.
