What to do with condensate from condensing boiler

Limestone and marble are good and inexpensive neutralizing agents. The smaller the pieces, the less required as you have greater surface area. If you're going the home-made route with a 5-gallon bucket or big plastic tub, nearly any size stone will work because you have a vast quantity compared to the manufactured units. Do check and add stone periodically as it is consumed in the neutralization process.

    Is it ok for septic?

    Going to install a W/M 230 Ultra in my shop. Am on a septic system. Do I have to treat the condensate before going into my septic system? If so, how? A big Alka-Seltzer? (that was a joke in case you missed it). Have high temp emmitters so I don't think I will be getting a whole lot of condensate, but I don't want to damage septic system. what info do you guys have on this? thanks in advance,
    Rocky.

    PS. It snowed two nights ago and hasn't melted yet. Calling for more snow with temps in the high 20's at night, mid 30's during the day. Sigh. Life as me and Weezbo know it is over! At least til late April!

    Its, (the condensate) suppose to go through a neutralizer. The condensate can be a bit acidic and over time will rot out most things it comes in contact with. There are some folks here (on the wall) that will make their own out of a spackle bucket and some (like me) will buy them.

    If it is a concrete septic tank

    I would for sure deal with the condensate. With a plastic tank the condensate would pass through to the leach fields. Although it may upset the bacterial action innthe tank? A neutralizer is very simple to build, probably worth the time :)

    steel tank for septic

    Will probably use home-made neutralizer. How about the "prilled limestone" that you spread on your lawn? comes in handy 35 pound bags, already a granulated form, should work well, don't you think? A couple of scoops in the Tupperware tub and watch the "fizzle".

    Thanks,
    Rocky

    PS, calling for up to 2 inches of snow tonight. Haven't seen any temp above 40 in a week. I'm afraid I might as well accept reality and gear myself up for 7 months of 7/14's. Sigh.

    Where do you live? Alaska? Canada? Rockies? Sounds like winter is almost there.

    An interesting aside. Around here our "limestone" is dolomite, or dolomitic limestone, which is a better building stone because the base mineral in the stone is also dolomite and not calcite, which is the base mineral in limesone and leaches with water. I suppose the lack of the calcite would mean that it would be useless as a neutralizer. Any geologists here?

    should work fine

    Rocky,

    My home built clear column uses rock, but I bet your stuff will do as well.

    Just have to ask how a septic system works when you have permafrost.

    Did some web searching and both forms of limestone are used for agricultural (acid neutralizing) purposes. Tables showed a slightly higher application rate for dolomotic limestone to achieve the same ph change. A reasonbly small "crush" of either would [seem] suitable.
