I need to replace my existing pneumatic button flush, as the rubber diaphragm that lifts the flush mechanism is leaking, and was wondering whether I should go for another pneumatic, or are cable ones more reliable?
The outlet hole seems to be 40mm internally, but the pipe looks to be 50mm externally, so I don't know whether I need a 1½" or 2" fitting, but I can get one with fits both. The push button hole is 40mm, and it seems that 38mm is a fairly common size, and the button is fitted to the front of the vanity unit.
So I just need to decide between cable or pneumatic. I have read comments that imply cable ones are easier to operate, but the cables can rust up, whereas pneumatic ones tend to be more prone to leaks (as mine is).
Does anybody have any recommendations?
