Thanks Tony?

Tony Thanks for the info.
I looked at the pic and ajusted as you suggested although nothing changed.
Looking at the pic.
The ballcock arm, when it fills up and the little hammer touches the part to close the water off. I ajusted the hammer screw and it has made a diference.Tony I would not have done this if you had not given me the advice.
CAN YOU ADVISE WITH REFERENCE TO FLUSHING AS WE HAVE TO PULL THE HANDLE 3 OR 4 TIMES FOR IT TO RELEASE EVEN WITH THE RIGHT LEVEL OF WATER.
It seems the handle has less resistance although pulling the handle 3/4 times rapid it does release.

Regards
