Just a head up.

I learned this the hard way. The condensate from the combustion of natural gas in high efficiency gas furnaces is highly acidic. I know because it destroyed my basement sump pump in 2 1/2 years. The pump started spraying water and when I removed the radon cover I found the pump covered in white corrosion. I did some research on line and found out that the condensate is high acidic. From what I read it can completely destroy a cooper drain line in as little as 5 months. I am investigating adding a filter that will reduce the acidity of that condensate to prevent the destruction of my next sump pump.

I am not referring to condensate from air conditioning but from the combustion of natural gas in high efficiency gas furnaces. Some municipalities are requiring these devices to reduce the acidity of the condensate.
