Not sure what plumbing you're talking about modifying. If you did
go with a new 240V powerpack, you may just have to change that, and
not the heater, pump, etc. That's how mine was set up. It uses the
same heater at 240V, it just puts 240V across it instead of 120V,
giving you 4X the watts. The pump, blower and light in mine all work
on 120V either way.
If it were me, I think I'd just rig up power to it temporarily to
verify what works and if it's worth salvaging.
