For folks from other parts of the country, it's rare to have an "in well" pump in Florida. Most pumps sit on the pump head. Wells just don't need to be that deep.
For the OP. In the nearly 40 years I've been pumping water out of the ground in Florida I can tell you it's a PITA. Get ready for a tumultuous ride. Earlier this year, the weather, it was dry. My pump kept losing prime. Eventually, I had to replace the burnt out pump. I'm guessing that may be your problem. If municipal water had been available years ago, I would have been thousands of dollars ahead. Septic tank was a worthwhile investment. It's the sewage treatment part of a typical municipal water bill that is the big hitter.
Well rules:
When the well fails for whatever reason, it will be on the weekend.
Repair costs will usually be triple what you expect.
Finding a reliable well guy is like finding a good car mechanic and if and when you do find one it's gonna cost.
One other point, check to see if you have a check valve inline to your house. You should. At any rate, the water pressure in your house may bleed down overnight. Turning off the pump at night may save the pump, but pressurizing then releasing pressure allowing air to possibly enter the system will raise cane with your plumbing.
Just wait till a hurricane takes out your power for a week to 10 days and you've got a house full of females. In 2004 I got triple hit with hurricanes. Lost power every time for at least 5 days. The worst was nearly 3 weeks. I had a pool full of water, but I couldn't make those women understand that you didn't need to pour a bucket of pool water in the toilet tank, then flush the toilet, just dump the water in the bowl, it'll flush. I did have a generator, but it was time shared trying to keep food refrigerated, frozen and cooked. Naturally, the TV has to blast 24/7.
