Toilet making hissing sound

Bobby3210

Hi folks,
Hope someone knowledgeable can help.

Our toilet has been making a hissing sound for about a week and I understand from googling that it is something to do with the fill valve.

I took the lid off and can see water sprays out of the white thing. I think I need to take the diaphragm out to have a look at it but cannot get to it.

Please can anyone help on how to get to the diaphragm. TIA

I vaguely remember taking one of these apart and I think I unscrewed the bit that's half way between the ends of your two orange lines - you can see it almost looks like the cap of a bottle, with ribs to help you get hold of it whilst unscrewing. I seem to remember there being a kind of diaphragm inside there with a pin going through it and I cleaned it out. Someone else may be able to give a better description.

Thank you. Upon further googling it appears the diaphragm is indeed inside the bit that looks like a bottle cap. I will unscrew tomorrow and check the state of it. Thanks again

 Untwist the screw that resembles the lids of the bottle. And replace it with a toilet fill valve. It will work perfectly. It is the only one that fits in the tank.

We should hope that 329 days later the OP had already solved their problem a long time ago. So resurrecting a very old thread may not be that helpful to anyone.

Welcome to the forum BTW.
