Overloads don't trip a GFCI. Period. If there was an overload, it would trip the actual circuit breaker. Since this is a GFCI/receptacle (as opposed to a GFCI/breaker) and the GFCI trips, that is a ...

How can I seal a foundation vent?

I'd suggest that the problem is the flower bed, not the vent. Grade should be reduced and sloped properly to prevent the problem. Consider rain gutters in the area. You could also switch to a flower ...

Is there a reason to replace 50 year old metal ducting in the crawlspace with modern insulated flexible ducting?

I see no reasons for replacing the existing ductwork with flexible insulated ducting unless the existing ducting has rusted out. I would just re-insulate with 3” fiberglass wrap if the existing metal ...

Fastest way to dry a vented dirt crawl space (no vapor barrier) in California (Bay Area)

Fastest, without tearing the house apart: 4 fans sized to your 4 vents - two blow in, two blow out. Less fans will probably work fast enough, but 4 would fit "fastest" as requested. If you ...

It seems to me the biggest problem is if your heater doesn't turn on and you don't know about it, right? If it fails to turn on but you do know about it, you can address the problem. As such, if it ...

Draining to the sump pit is a common choice. Another method is to use a small, automatic condensate pump to lift the water up high enough that it can be directed to another drain.

Fastest way to dry a vented dirt crawl space (no vapor barrier) in California (Bay Area)

For standing/very wet surfaces fans will be the best(besides mopping/sponging/pumping). You want a good breeze blowing in from one end and out the other. Amount of fans will depend on area.
