If you have a valve on the cold pipe going in to the toiet you can turn it down to reduce the flow going in & hopefully the noise. No need to call a plumber for that
If its a ball valve you will need a flat blade screwdriver.

Dear David,

Do not turn your mains stop tap down. This will have an impact on pressure potentially in the whole house particularly if you have a combi boiler. With regards the toilet I would simply replace the inlet valve (torbeck) there are various options with most having adjustable heights to cater for different cistern shapes/sizes some also come with restrictors which you install for either high pressure (HP) or low pressure (LP) the HP one for mains fed. With regard the tap that may simply be and issue with tap and needs replacing difficult to say with out seeing that one.

Isolate feed to toilet cistern and strip down the filling valve, can just be a small blockage, or replace the unit.
If you don't feel confident enough then use ourselves or someone on the site to come out and change it.

This is normally the diaphragm on the float in the toilets cistern, occasionally it could be the ball valve, if there is one. If I was you, for the price of them I would replace the whole lot.

Hi
Inside the ball valve their is a changeable part called the orafis, this can be for mains pressure or low pressure I would of thought you have the low pressure one inside.

Hi there,you may have an old style ballvalve,which you can try replacing. or it may be your pressure is too high from the mains in which case you can fit a pressure reducing valve........Brian
