Electolysis in Solar Storage

solseansolsean Member Posts: 16
Saw this years back but the electrolysis went after the walls of the tank. The original installer used dielectric unions back in '97 and they have formed quality stalactites. Looking for any suggestions on how to get whats left of the unions off of the stainless nipples.

    you may have to carefully split them with a fine tooth hacksaw

    What type of fluid in the tank? Water with high conductivity, like softened water accelerates electrolysis

    I’d re assemble without dielectric unions, they tend to cause more problems

    The plan is the grinder. The tank fluid is water at 0.20-0.22 EC. There will be no unions if the system gets rebuilt.
