Replacing Zodiak intercommunication valve
I am attempting to replace an intercommunication valve for a zodiak Mark III and need to figure out a way to break apart the old valve and remove it without damaging the boat or compromising the integrity of the existing glue which is relatively old, (1974). As the fitting is brass I am troubled as to how to cause contraction without damaging any undamaged parts. My best idea thus far is to use dry ice and heat to cause the broken fitting to contract and break off without causing any of the above mentioned potential damage. Am I on the right track? Is there an easier less risky solution? Most of all a cost effective one, that will leave the boat undamaged? Thanks in advance for your thoughts and advice.
