Hey, ive got a scooby and have a baileys dump valve that is a loud deep wooooosh sorta sound. What dump valve does the more high pitch sound? also they dump valve with the higher pitch seems to need less presure ta dump, mine needs alot of pressure before it will dump loud?
if i remember rite you can adjust the control settings for your dump valve so that it will dump at a lower pressure and a lower pressure dump should also give you the sound that you are looking for.
