Condensate Pump?

will attack iron, yes. It may not happen right away but will eventually. I would not only pump the condensate I would neutralize it first using marble chips. If you had PVC plumbing I would not be concerned.

    Condensate Pump?

    Recently had a CGi-3 installed. But the installer ran the hose from the tee on the safety-seal exhaust into a piece of 3/4 tubing he put through the basement floor. Our house is on sand, pretty much. The length of the exhaust is about 20 feet. I don't know if it's worth pushing them to install a condensate pump or not? Will the condensate water cause any damage to my cast iron main drain line? Any suggestions will be greatly appreciated.

    Brad... would you agree that it may not be a good idea to pump that into a septic system?

    I do not have a strong opinion on that one way or the other especially if neutralized.

    When you run the condensate through marble chips there is no "control" on the outflowing pH but the low flow rates would indicate a much higher pH (closer to neutral that is). Given that plus occasional normal acidic pH discharges with all the dilution inherent in that kind of system, I do not see an issue if you have PVC piping. If iron piping I would find another way.

    As to how it affects the bacteria necessary for septic system operation, I really do not know. Perhaps others do?

    Absent better information, I would dispose of the condensate in a drywell where, if you do have a septic system, your laundry would also be discharged. (Chlorine bleach and septic systems can be a problem. Naturally this would also be separated from the boiler combustion air, right?) Point being, a neutral location (so to speak) would erase any doubt.

    One thread here some months ago had the condensate discharge below grade but offered that blueberries thrive on the stuff.
