A swimming pool is a body of water where people may swim, exercise or relax. These water features can range from inexpensive portable play equipment for kids to major landscape features that cost hundreds of thousands of dollars. Budget, lot size, local codes and availability of materials will all influence which type of swimming pool is ideally suited for your home and family.
Pools are usually constructed of vinyl, fiberglass or concrete, and are often finished with a plaster surface. Concrete pools can be poured, shotcreted (a mixture of cement and sand) or made of Gunite, a form of precast concrete. Gunite pools are often built with a more rugged and durable surface than poured concrete pools.
Swimming pools need to be sanitized to control levels of bacteria, algae and other pathogens in the water. Chemicals, mechanical sand filters and other means are used to achieve this goal.
Water quality is important, and the ideal pH for a pool is between 7.4 and 7.6. Anything lower than that can lead to metal corrosion in the pool. Anything higher and chlorine becomes ineffective as a sanitizer.
Proper weekly maintenance of a pool can cut down on costly repair bills. Regularly cleaning the hair and lint pot on the pump, keeping the water level up, and adjusting chemicals can help keep your pool in tip-top shape. It’s also a good idea to consider alternatives to chlorination for sanitizing your water. These include ionization, oxidation, natural plant-based methods and solar thermal heating.
