When we pressure test plumbing pipes we use 4psi. Believe me, when a cap blows off there is a loud pop!

Water cannot travel in the tiny crevices where solvent can. I would start with about 2psi and use a spray bottle of soapy water if it doesn't hold pressure. When the tank starts bulging you'll know it's enough pressure.
