The cup type is very easy to install. Watch the video below for a guide on how to install one.

Installation

First shut off the water supply and flush the toilet. Remove all the water from the toilet cistern. Using a spanner and some grips, loosen the nut holding the water supply and remove. Remove the next nut up and remove the old valve. Install the new valve in reverse. To alter the water level in the cistern, use the thread on the upturned cup to lower or raise the cup height.
