how to neutralize boiler condensate?

I have a Munchkin mod-con boiler running in the basement of our 90-year old house. Untreated boiler condensate drains through some PVC then into the basement floor drain. I checked the pH out of the PVC and it is right about 3; I don't think the old pipes are going to like that for very long.

So I read on this site (I think?) a great thread earlier this fall (?) with instructions for how to use PVC etc and some kind of stones to build a cartridge to neutralize the condensate. But for the life of me, and search as I may, I can not find the thread. Sure would like to find that thread but ... any ideas on a DIY solution for this problem?

Condensate

The manufacturer sells a neutralizer kit for the condensate. Their number is N1100. If you check Munchkin's site you might be able to get an idea as to how to make one.

I believe you could get calcite, used for pH control in water conditioners, at most plumbing supply houses.

If I recall correctly, the neutralizer is basically a PVC cylinder filled with marble chips. The acidic condensate is neutralized when it reacts with the marble. I've directions on how they are made, but can't remember where? They can't be that expensive...

that's what I saw, it was a thread over in boilers, marble chips in a PVC cylinder. I'd rather not buy from the manufacturer if the DIY method works fine.

Where do I get "marble chips" or something similar?

I had some kind of browser refresh issue, I saw 5 minutes ago that there were zero responses to this thread so I posted the same thing over in boilers, where I meant to do this anyway ... sorry mods ...

Marble chips can be had at a home store. Usually used as cover on flower beds or something like that.
