My walk-in freezer's drain line froze up last Tuesday night
I thought it was a quick fix, maybe an hour with a shop vac and some hot water. Ended up being a full clog in the line under the floor slab. Had to pull the evaporator unit to get to the cleanout, and the whole thing took me almost nine hours into the morning prep shift. Lost a case of duck breasts and a whole hotel pan of demi because the temp spiked. What's your go-to method for preventing this mess when the humidity gets wild? I'm not doing that again.

Ugh that's the worst kind of night. Honestly, I just pour a little hot water down the drain every single night before I lock up. Like a small coffee pot's worth. It's cheap and it keeps things moving. If I know a big humidity spike is coming, I'll hit it with the shop vac first to pull out any sludge, then do the hot water. It adds two minutes to closing and saves a nine hour nightmare.

That hotel pan of demi is a real gut punch. I run a small line of food grade RV antifreeze down my drain once a week. Just a cup. It's cheap and stays liquid way below freezing to keep things clear. @dixon.james has the right idea with nightly hot water, but the antifreeze is my backup for when I forget. Also, make sure your drain line has a proper slope all the way out. A flat spot under the slab will always collect water and freeze solid.
