    Default Max Vertical lift of Condensate pumps?

    Anybody got a guess at what the maximum vertical lift a condensate can pump water?

    Today's basement had a 16 foot ceiling and the condensate pump was trying to lift water from the basement floor up and out the sidewall about 3 feet above grade level. Roughly 19ft, over a hairpin turn in the flex line.

    There was rust running out of the A/C unit so presumably the condensate lines were backed up.

    Tried posting pics but apparently there are too large.

    Whatever the pump is rated for, there are several sizes, capacities, and HP of condensate pumps.

    Here is a site that shows your basic pumps. It looks like you are right at the cut-off point for the smaller ones.

    Also be sure the discharge line is properly sized.

    Thanks! Should have googled around a bit. Looks like common sizes provide 13'-15' of lift. Probably undersized pump for the particular installation.
