Hi all… I have just replaced my MY95 with a MY97 and with it came a DUMP VALVE. One which seems to be NEW (certainly newer then the can because it is very shiny!). It also makes a lot of noise. Anyone know if I can ‘quieten it down’, replace it altogether (and what do I replace it with?), or anyone want to swap it with whatever is standard? Trev (Harrogate)
