When reopening your pool for a new season, make sure your pump and filter are working properly before adding chemicals to the water.
When cleaning the surface of your pool with a leaf net, work your way around the sides first, then clean from the middle of the pool to the sides.
If you use your pool only on weekends, reduce your heater thermostats settings by eight to ten degrees during the week. Furthermore, when leaving for vacation for more than a week, turn off the pool heater, including the pilot light.
When closing your pool for the season, coat all accessible o-rings, rubber fittings, and gaskets with a silicone O-ring lube to keep them from drying out.
Store your pool chemicals out of direct sunlight to prevent breakdown by UV rays.
If you are buying a house that includes a swimming pool, plan to have the pool inspected separately by a pool specialist, not by your home inspector.
