Condensate Neutralization & discharge to building serwer

hr

Get some PVC or ABS reducing couplings and a section of pipe. Toss in some marble chips, get them from companies that do marble counter tops.

Actually I use limestone gravel :) After seeing what condensate has done to a slab where a condensate line from A Voyager drained, I can tell you that condensate is powerful, and will eat a groove in a concrete floor in short order.

I imagine if the entire plumbing system was plastic, and the home was on "busy" city sewer, I'll bet that condensate gets pretty diluted before it can cause harm.

However if the home is on a septic, with a concrete tank, you best be neautralizing. Especially a low temperature radiant boiler which can condensate 5- 10 gallons a day!

What are you doing with your condensat?

I have a readily accessable laundry sink near by to discharge my (High PH) condensate from a new condensing boiler into.

*What type of neutralization is required?

*Where should I be looking for this device?

* What would ME do? Hi Mark:-)

Key to success on condnsate disposal

is to not put it into a metal DWV Taht is at the end of a line. It is best to treat with limestone as HR describes and try to locat in the drain system where it can be diluted with water rom other sources. Back in the mid 80's a Sutch boiler manuf (Remeha?) of condensing gas boilers had done a thorough study on this topic and found taht if disposed of as described it had no deleterious affect on the plumbing system. I once had a guy use a condensing oil furnace for temporary heat while building his house. He just let the condensate run out on the basement floor. Idiot! He called me in the spring and wanted a new furnace "cause the other one ani't no good." The bottom of the furnace was gone and his 4" slab was about 2" thick. So, don't just drill a hole thru the concrrete floor either.

What I'm doing with my condensate...

I'm distilling it even further and making boiler beer out of it:-) Figure I can sell it to Wallies.

Just kidding. Personally, I've got a 5 gallon bucket with 6" of white landscaping marble in the bottom of the bucket. On top of the marble there is a condensate pump with a float actuator. The condensate sits completely immersed in the marble. My pH meters batteries are dead so I can't tell you the net effect on pH. I'll get new batteries tomorrow and let you know how it works.

By having the 5 gallon bucket in the laundry room, I figure I'm colecting about an additional 8,000 btu's per gallon of condensate produced. Obviously, production depends on demand. In any case, it's better than pouring the btu's down the drain. I've tested the pH of the condensate coming out of the condensing boilers I work on, and it is low, around 5 to 5.5. I've seen this take the bottom right out of a cast iron floor drain. Can only imagine what it did to the branch drain between the floor drain and the point of substantial dillution. I know it is illegal to dump untreated condensate in Europe. I think they know something we don't...

Here's a picture of my personal neutralizer.

Too bad you couldn't bring us some of that yummy sounding "Wallie brew" to Iron-n-beer night Thursday.

Which is better at neutralization, limestone or marble?
If you've got the pump on top of the marble, what do you expect the lifespan of that pump to be? I like HR's flow-through idea.

8,000 btu's per gallon of condensate produced? You save that? What a Heat Miser:-)

Wallie Brew.,,, LOL

Mark,

Too bad you couldn't bring us some of that yummy sounding "Wallie Brew™" to Iron-n-Beer night on Thursday. Probably better than that Coors stuff. (not hard to do)

Which does a better job at neutralization; limestone or marble?
