A customer email about inside odor in Winter Cabin
Posted by on
I have owned a cabin for 10 years and was very pleased that the septic smell went away this summer after installing your device on two vent holes on the roof of our cabin. During the winter I leave the heat on 50 degrees and went and checked on the cabin this weekend after some bitter cold in South Dakota. The cabin smelled like septic gas. I turned on some fans and filled all the traps with water and it did get better but by the next day the smell was coming back. Do I need to remove them in the winter? I just wonder if the charcoal got wet then froze and is not allowing the gas to escape. This is the first time in ten years I have ever smelled the septic in the house. Please advise, and thank you.
Hello OdorHog Customer,
Thank you for your email. We're sorry to hear about the inside odor you encountered. It sounds like your cabin's vent system isn't being used during the Winter, so no water is being run, no toilets are flushing, which means no air moves up your vent stack. Unfortunately, this leaves the roof vents on the outside of the cabin, exposed to freezing temps. Your vent system, when in use, has a warm, moist stream of air moving through the carbon media continually, which means your vent pipe is a wet environment. With the sub-freezing temps and no continual moisture wicking up through your vent pipe, your carbon has probably frozen into a block and is restricting air flow.
If you aren't using the cabin continuously, then yes, I would remove the filters until things warm up in Spring. Leaving the heat at 50 degrees inside the cabin won't keep the OdorHog from freezing up on the roof without the vent system being in use.
Our filters contain a freeze protectant similar to rock salt that will keep a filter from freezing, only if it is in continual use during the winter. Please let us know if you have any other questions.
