Periodically check your pool for leaks if you have an automatic refilling device.
Install covers on pools and spas and check for leaks around your pumps.
Make sure your swimming pools, fountains, and ponds are equipped with recirculating pumps.
Use a grease pencil to mark the water level of your pool at the skimmer. Check the mark 24 hours later. Your pool should lose no more than ¼ inch each day.
When backwashing your pool, consider using the water on your landscaping; some dilution may be required.
Avoid installing ornamental water features and fountains that spray water into the air. Trickling or cascading fountains lose less water to evaporation.
