How can I prevent condensate drain line from freezing on my Navien tankless water heater. I have a high efficient furnace and the 3/4" condensate drain line that protrudes thru the wall just enough to install a ninety to direct flow downward. I had problems with this freezing and didn't have room to install heat tape. I built a small enclousure and installed a small light bulb. Light was emitted thru open bottom which my wife complained about ever since I installed. I recently cured that by installing a ceramic bulb which emits no light. However, I don't wish to do this again. Also, I can drain into septic tank thru neutralizer I purchased from Navien, but that will require testing the ph of the neutralizer. Also, how do you know when to test it? Love the high efficiency heater, but this stuff has been a thorn in my side. Appreciate any suggestions.
Thanks.
