could u help with y it is coming off? also wat can i do 2 stop it many thanks

 

maybe the diaphram has gone in your valve mate or just cut the end off the pipe and refit might be stretched. if not that check its not blocked by anything stooping the air getting through the pipe.

 

hi the air is geting throu wen the pipe is off so dont think anything is blocking it. it only seems 2 have stared 2days ago. thanks
