Winterized cabin/well questions

Hello everyone. I have a cabin that I am fixing up to live in full time, but I'm not there yet. I'm zone 4a, our last frost date is June 1. We winterize our cabin in fall and keep it off until last frost in the spring. I want to plant a lot of plants this year, and would rather not hump water up from our pond. Here are my questions:

1. For the pipes inside the cabin, is there a difference between a frost and a freeze? Like, if we turn it on mid-may, but we get another frost or the air temp hovers around 30-32 for an hour, will that burst the pipes? FWIW the cabin is usually 10 degrees warmer than the outside air temp.

2. We have a frost free electric well spigot outside. Would it be possible to turn the electricity on to the well, but to keep the electric off to the pressure tank in the house?

Hi Rachel;
I would say as long as an artic freeze doesn't happen in May...  you'll be fine.
It takes much colder temps for many hours to freeze and split copper pipes, plastic pipes tend to stretch if temporarily frozen.
Although I doubt it , you might temporarily freeze but as long as the temps come up within a few hours they will quickly thaw.

You definitely should be able to power your well without sending any water to the pressure tank.
Or any water to the house at all if it has an inline shutoff at the pump house or perhaps under the real house.
Using your outdoor frost free would be the safest until you live on site.

Thank you Thomas. I don't think there is a shutoff outside. It is a spigot that is next to the well, maybe 100' from the house. Although I do believe there might be a shutoff by the tank, also the tank is on a separate circut from the well.
