A pneumatic flush has become increasingly difficult to operate so much so that the button has to be kept depressed for the whole duration of the flush. I disconnected the plastic tube from the button and gave it a good blow but to absolutely no effect. So the push-button would appear fine but I am guessing that something in the valve has failed. I have not had this happen before so would appreciate advice on how I might sort this out. Thanks.
The valve is Armitage Shanks conceala 2 SV80367.
