Cistern only filling part way up/weak flush

[thomasbrig]

Hi all, quick one here - my flush is pretty weak and doesn't always get rid of what's in pan...my cistern only fills a third/half way up. Is there any adjustment I can make to get a bit more strength in the flush? Cheers!

Turn the threaded plastic rod to allow more water in. You want it about 25mm below the top of the Syphon (the underside), can't quite make out where yours is.

You can fit a taller syphon if it is too short, the existing could be a country pattern (shorter in height).

Use a Phillips screwdriver to rotate the threaded white plastic rod of the fill valve clockwise to raise the blue float.
