Actually, It wasn't in reference to ac condensate, but rather the furnace condensate as they usually combine into one location. The pH could be a concern for components but a small pump and hose isn't too big of a deal to replace if ever needed. Septic systems, maybe, but still not sure of the daily quantity that may go into the septic tank and then it is diluted by all the existing tank water and fresh grey water coming in on top of it.Interesting thanks.
Nothing here surprises me outside of the company pushing a installing condensate neutralizer systems for high efficiency gas furnaces very hard -- just to put the condensate in the wastewater system. I am a little skeptical that is necessary for homeowners to (Ph?) treat condensate to release into the into a wastewater/sewer system to make it less acidic. I maybe can see the point a little more if you have a septic tank and a very big air conditioner system draining into it. But it is news to me (I am just a DIY guy though, but also a scientist) if hardly any high efficiency gas furnaces come with a condensate neutralization systems. I very much doubt that little acidic water mixed into the large waste stream will not do any significant harm. I also doubt any modest treatment system is going to remove trace heavy elements (the real problem which will also depend on your system, the gas supply etc) also. This company may be targeting people wanting to be responsible citizens for profit. The money that their customers spend on a such condensate neutralization systems might be better spent on things that potentially matter more and be more doable: Like putting a microplastic filter in a washing machine drain to better keep micro-plastic shards from synthetic clothing out of the waste stream.
My point really was, DON"T DRINK IT (as mentioned in above post). Not even sure I would want it on my garden veggies. Flowers ok, but you may find they croaked one day too! A hole in the basement floor has worked well for me for 31 years.
