Having the power on is a major win for sure. Now let’s plan on it happening again and get you ready.
Using a tarp and building a “tent” around the equipment would be a major help. This will block any wind and rain plus help keep some heat inside. Assuming you’ve got power, place a heat lamp or incandescent bulb under that tarp. This will help block the wind plus provide small amounts of heat to your equipment. This plus keeping your equipment running on high should help while you have power.
If it goes out again be prepared to pull any plugs in the equipment to drain all the water. Know how to drain everything. Don’t worry so much about the plumbing if the power goes out, focus on the equipment. Once everything is drained then go ahead and wrap the pump with a blanket and such to give extra warmth.
