Winterize pressure tank
Hi guys, I have been reading a few things on this site and your information is very helpful and much appreciated. I purchased a fixer upper in northeast PA. Which has one of those blue water pressure tanks in my crawlspace. I drive for a living and I winterize when I leave. I drain the pipes that I can and add RV antifreeze to my traps and toilet. This past week however was very cold and the ball valve and a pipe came apart from freezing as well as water freezing inside the pressure tank. My question is until I move the tank and inclose it will these next five steps work to winterize my tank?
1 - Turn off the power to the submerged well pump.
2 - Run the water until it stops.
3 - drain the tank by the drain valve on the tank, also emptying the pipe with the ball valve on it.
4 - When I return home put a small electric heater near the tank to warm up the bladder.
5 - Turn on the power and refill the tank.
Are these step advisable?
Thank you for your input, Sincerely, Ron
