Draining dehumidifier into sewage pipes in crawlspace?
I'm thinking of putting a dehumidifier in the crawlspace.
The humidifier I like most (dry eaz cmc 100) has a built-in pump. However, it can pump water only 3 feet high, that means I cannot pump the water up one floor into one of the sinks. There is no foundation drain visible in the crawl space that I can use. There are 3 and 4 inch black drain pipes that leads out to the city sewage. Can I drill a small hole in one of these black pipes and stick in the dehumidifier's drain hose? This would be less than 3 feet above the dehumidifier. But I wonder if it would cause any problem if large amount of water is being flushed down from the living area. Is there anything in (USA) building code on this issue? |

If the dehumidifier's pump were strong enough to lift the water an additional twelve feet, and you punched holes in the floor, etc., such that you got the condensate line to a sink, where do you think the water would go then? |

Pump it up 2-3 feet and add a gravity line to the outside. I have a condensate pump on a 90+ furnace and AC that works just fine using this method. You are risking drain leaks and sewage in your crawl space when you tap a drain line. |

Our county code prohibits all sources of liquid that are not directly related to our water supply from draining into our sewer system. So, by our code, air conditioning condensate, and the condensate from our high efficiency gas furnace must be pumped outdoors. If we had a stand-alone dehumidifier, it would pertain to that condensate as well. Don't get me started on the logic of the code. |

You are risking drain leaks and sewage in your crawl space when you tap a drain line. Reasonable alternative but also extend the line at least 10 ft from the house foundation. It's a given if he is putting a dehumidifier in his crawl he has water issues. |

So, let me get this straight: You have a tail-gate party at your home with a few friends. You watch the game. You and your friends consume copious quantities of beer that originated from pristine Colorado streams and brought directly to your town without ever having reached room temperature. Do you have to go out to the street and pee in the storm drain? **** in an empty five-gallon water bottle and FedEx the used beer back to Colorado? Take a large container of urine to your mayor's houe with the notice "It's not mine, it's urine!" Perplexed minds want to know. |

Dr. Laura Schlessinger mentioned that concept as being common with
Jews. She'd ask "What, you don't like my dinner?" and a Jewish guest would reply "what's not to like?". Was Socrates a Jew? Would that be an issue? Which came first, the question or the question?

And doing it the right way, installing a trap is gonna be a major pain in the ass. With a 3' lift capability, in almost all cases, it should be possible to run a small hose outside the crawlspace to let the water drain. |

Perhaps I'm not picturing what you mean by crawlspace.
The crawlspaces in houses I've lived in were not sealed - there was plenty of air transfer. Therefore, running a dehumidifier is equivalent to trying to dehumidify the whole neighborhood. It would run continuously and accomplish nothing. Maybe your set up is different, but I'm inclined to think ventilation is a better answer than dehumidification. |

Another part of the equation might be a vapor barrier over the ground. I have yet to see a crawlspace with a dehumidifier. |

Any water under the house increases the likelihood of mold growth not
to mention a mess and possible structural problem. Dehumidification as you know can produce quite a bit of water. This water is essentially distilled water and is pure water (better than our well water). We collect ours an a 5 gal pail and use it for watering the garden and house plants rather than run it out on the ground to make a summer time mud puddle. |

It looked like the family room was an afterthought and the foundation extended for it. The "crawl space" was excavated down to the footings (7') but there was no floor or access to the area. Maybe your set up is different, but I'm inclined to think ventilation is a better answer than dehumidification. I had vents added to the space (and insulation covered in Tyvec) and left the window open year-round. That seemed to take care of any moisture problem. |

Maybe your set up is different, but I'm inclined to think ventilation is a better answer than dehumidification. Vented crawls used to be SOP here in midwest, until they realized it was easier and cheaper to prevent the moisture, than to give up all that free ground heat in winter. I haven't seen vents on a 'new' crawl in thirty-some years around here. A modern crawl with sidewall insulation seldom freezes hard, even if house furnace is off. That is a lot shorter hill for the furnace to climb in the dead of winter. Of course, few people build crawls now around here, other than on cheap tract homes, glorified trailers, and lots with high water tables. Unless OP has a high water table or a spring, I'd regrade the yard and redo the gutters, and dry the damn thing out, first. Even add an outside french drain, if none exists. Don't have to dig very deep for a crawl, just a foot below frostline or so. -- aem sends... |
