Condensate pump leak

Condensate pump started leaking today from the base has it has never leaked from 2012 and it's leaking through a hairline crack at the base. Has anyone ever seen this before? I can only assume that the crack was there all along and the acid in the water eventually just ate through it .

    Can you provide nameplate brand info and pictures?

    Usual condensate pump leakage is due to leakage at shaft seal. Sometime leakage will wick to other area giving false impression.

    Typical shaft seal life is 10 years.

    I've never seen leakage due to acid in that short a time period. Do you know what the pH is?

    It's common to have a 20 yr. warranty against corrosion failure of cast iron condensate pump receiver tanks.

    If leakage really is due to a crack, these will sometimes seal themselves up due to rust build up. Of course this would have to see no pressure until the rust sealed the crack.

    You know what happened when installer must of installed it with the crack and adjusted the float to kick on earlier. So years later it's kicking on later so it's hitting the crack and leaking. Just replaced. It's Liberty pump

    Probably got brittle over time and the stress of the screw holding it on influenced the cracking
