We have a bleed back water pressure tank installed so the well water pipes wouldn't freeze. It did, anyway.
Why would the pipes freeze if we have a bleed-back pressure tank? I have been told that the PRESSURE TANKS aren't "bleed-back" but the valve on the pressure tank is. I am so confused over this and my plumber is making a lot of money off me.

The bleed-back valve is designed to dump the water from the bladder tank back into the well when the pressure drops in the tank. This will keep the lines empty so water doesn't sit and freeze in them. The problem is for the bleed-back valve to work properly, you have to drop the pressure in the tank, essentially to zero.
What you should be doing prior to freezing temperatures is shut off the pump and open up either a manual valve on the tank itself, or the faucet lines to a slow drip, or both to relieve the pressure. Only then will the bleed-back valve be doing its job of draining off the excess water from the tank down into the ground where it won't freeze. No water in the system means your pipes should be safe from freezing.
Sorry to hear about your problems. I hope this information helps you out.
