My pool is about 4 1/2 summers old. When it was built they trucked in water to fill it. Since then, I had to top off with well water that went thru a softener, but im sure still had lots of minerals in it. Last summer we had city water finally run in front of our farm, and up to the house. Man is city water nice!!! Over the last few years I seem to get stains often on the steps as well as anything white. It comes off with a little acid poured in that area when I am lowering ph, but comes back within 30 days or so. I figure the water should be replaced. My pool is inground, 20 x 50 vinyl lined. How do I go about replacing the water? Do I completely drain it, clean, then refill?? I plan to put a couple of garden hoses in it to fill it back up.
I have heard stories about pools caving in but dont know if its true. We dont seem to have much ground water where the pool is since I have never seen a drop come from the pipe that drains from under/around the pool.
I also developed a few wrinkles in the shallow end last year when it go so hot. Can these wrinkles be worked out when the water is out and if so, how do you go about doing that??
