Greetings. I have purchased a house in Baja Mexico and I live there during the winter. During summer, I plan on being in Seattle for 6 months. I have a concrete pool with 1 inch square porcelin or glass tiles. They are grouted. My question is about draining the pool for 6 months. The water table is non existant. Am I looking for trouble by doing this? Is there a anger of the pool cracking? Danger of tiles coming off? Danger of seals in pump drying out? Other considerations? To keep it full will require a pool service of approx $1000.
