    Soldering Lineset?

    Hey guys

    Customer is relocating his heat pump. I gotta go pump it down and reconnect. He did a nice job. He used lead free solder instead of brazing. I didnít know he was doing the welding. Iíve never even thought about soldering except for water pipe. I read a article other day wasnít sure if it said it was ok or not I thought it said it was ok. Itís s R22 system. Can I leave it?

    95/5 then it should go but if the joints hold under pressure? After all its his system!

    Stay Brite #8 then its fine.


    FWIW 95/5 was used for many years in refrigeration systems.

    Specifically what solder, and what flux?
    I had a customer, soft solder a brand new system in with generic hardware store plumbing solder.
    It ran 3 weeks before the acid in the flux grounded the compressor.
