If there is residual water settling into to sump in sub-zero temps, will it freeze?
I could see this being an issue if so...

Water freezes at 32* F. That's a pretty good threshold for sumping/not sumping. My quick drains are frozen solid from October until April.
but just trying to figure out with the myriad of CFIs I've had over the years, I've not once had one tell me not to sump the gas below 32*.
...that really is the answer though.I'm happy to have a heated hangar now.
Remember to put the EPA fast response team on "speed dial" if you want to sump below freezing.
Just use your cigarette lighter to warm up the quick drain for a moment...
Do I sump or not when the DPE is monitoring the pre-flight?
Gawd NO! Just in case someone does try that, DON'T!
I don't recall being "monitored." I'm pretty sure I did the whole preflight and gathered up all the logbooks prior to his arrival. After the oral was completed he said "let's go fly" (which is secret code for "you're about to be a pilot") and when we got to the plane he asked a couple of questions about what I had done for preflight but he didn't have me re-do it.
If you do happen to have a brain fart and have a quick drain stick and drip? A blow dryer works to thaw the ice and allow the drain to seal. That's a pirep. We learn from our mistakes.
From my experience they do watch and ask questions as one preflights. Be able to explain what you are checking and for what. Know which antenna does what, stuff like that.
Interesting. So the message to @Sinistar is to talk with your CFI about how your DPE will be doing things. They'll be able to answer much better than SGOTI.
If he want you to do a pre-flight then Yes Sump.So here's one for ya....if all goes well I will do my PPL checkride sometime soon this winter. It will most likely be somewhere between 5F..20F. Do I sump or not when the DPE is monitoring the pre-flight?????????????????????????
SGOTI?
Ha! So True! Sometimes the sarcasm gets lost in translation.
Blow dryers blow the fumes the other way. Like I said....pirep.
And suck air in from the other end, but yes, I have seen mechanics in Alaska use a heat gun on fuel sumps in a closed hanger.....but I only watched them for a second before I felt a strong need to go outside and look at the stars.....
Sure, run a cheap, sparky motor in close vicinity of gasoline fumes. Kaboom!!!If you do happen to have a brain fart and have a quick drain stick and drip? A blow dryer works to thaw the ice and allow the drain to seal. That's a pirep. We learn from our mistakes.
Just have certain POA pilots breathe on it. The hot air should thaw it in no time...
