toilet doesnt flush great..what do i need

[steveo3002]

we have a 9 ish ltr cistern mounted behind the toilet in the normal position , tried a few flusher valves over the years , like screw fix and turbo flush

trouble is it doesnt always clear the pan in one go

what do i need to upgrade to for a more powerfull flush

[steveo3002]

pan swapping sounds like hard work...i was hoping a new cistern would sort it

but yeah i would like something to cope with heavy duty remains
