Condensation pump tubing is frozen
As some of you may know from my previous posts, I installed an Aprilaire humidifier. I routed the drain out to my condensation pump. However, last night the temp dropped down to 7F and the water in the tubing froze where it exists the basement.
I have a bump out from the floor above so the tubing does point straight towards the ground before exiting the floor, which I thought would be enough to let the water drain from the tubing to prevent blockage.
However, the tubing must not be wide enough because the water stays in the tubing like the way milk stays in a straw when you put your finger over it.
So, what's the best solution?
My idea is to pierce a pin size hole near the pump side so that it allows air in to let the tubing self drain, yet not be big enough to interrupt the pumping ability. My only reservation is that the pump may endlessly cycle on and off, as water within the tubing yo-yos back and forth from the tubing to the basin. Uhhhgg.
