You are using some sort of wax sealing agent at the
valve? I use Carmex, others use Chapstix...and I am
sure other products work well. Also you are pulling
the valve tight with the rigging tool? Only thing
else I can think of is to work the dump actuating lever
to free up the linkage.

somewhere in between.
I'm looking for help on how to go about sealing them
better.

I will get some new springs manufactured to push the
valves closed but I
would appreciate help on how to renew / refurbish or
repair the existing
seals themselves.
