Alarms are mandatory now on radon systems Hi Bob,
The power outage thing is a real wildcard, not really part of a normal operational expectation, though it obviously should be, once you've experienced it.
People are amazing, no amount of signage or warning helps, if people don't read. We get calls from sellers fairly regularly who read the first sentence of our closed house door hangers that go like this, "how am I supposed to go into or leave my house if I can't open the door"...my response is to ask them to read the 2nd sentence, also in 1" tall print. "Ohhhh except for normal entrance and exiting, I probably should have read that". So folks constantly disable mitigation systems regardless of signage too. Usually because that motor is either "too expensive to run", it keeps tripping the breaker or its too loud. The last 2 should warrant a call to the mitigator.... but it's easier to turn it off or unplug it. Jeez.
I have seen mitigators use a small water proof tackle box, mounted with tapcons to the exterior of the home to house the U-Tube outside. They seem to cost from US $5-$10. I've seen clear, translucent and opaque. Drill the correct size hole for the U-Tube, properly caulk the gap around the U-Tube line and presto, awesome little U-Tube housing. I'm not sure what temperature the fluid freezes up at, I suspect the tackle box scavenges some heat from the structure, helpng that a tiny bit.
