I am trying to decide whether it is worth it to redo a very large traditional cement and chlorine 65-year-old pool that has served me and my large family well for the last 36 years. This year the ancient pool pump motor started getting noisier and noisier, so it needs repair, but I have not been able to get anyone to come to either repair the motor (worn ball bearings?) or replace the entire pump. Also, I am having to add more water to keep the water high enough at a greater rate than ever before, so assume there is more leaking. The pool needs resurfacing or extensive patching, and the tile under the coping (which I did replace a few years ago) is crumbling away. (I have always kept it closed with an automatic pool cover, because of children and pets.) My spouse says that it is more worth it to just fix the pump and pay for the extra water. I, the dreamer, was thinking it might be a good time to put a smaller, shallower fiberglass pool inside the old concrete one so I could keep up my lap swimming and exercise into my extreme old age, should I make it that far. Then I would not feel guilty about wasting water. Downsizing the pool, in other words, since I can't bear to leave my house. My grandchildren now have their own pools or clubs to swim at so don't use mine much. But my first quote was over $100,000!! Maybe I'll need that money if I live for another 30 years. But if I die in just a few years, I will have had the fun of a new fiberglass saltwater pool that does not rough up my thin skin and water that does not break off my hair, and it can be used by whoever ends up with my house. Are other grandparents facing a similar decision? How do you decide?
