Q: Dear Owlie, 
I have noticed that I need to refill my pool and spa more frequently.  My family and I do not use it too much so I’m assuming it’s from evaporation.  As the summer heats up, I would like to invest in a pool and spa cover to reduce the amount of water that evaporates, but I am worried about the cost.  Do the gallons of water saved outweigh the initial cost of buying a cover?

A: Dear Pool Water Preserver

I am glad you are considering the purchase of a pool and spa cover.  During the summer, water in pools and spas can be lost to evaporation. This evaporation rate may be higher in southern California, where temperatures can reach triple digits.  With a cover, however, you can reduce the evaporation rate by 30 – 90 %, depending on the quality of the pool cover.  Yearly, a pool and spa cover can save the average homeowner 4,844 to 7,161 gallons of water.  To learn more water-saving tips, visit ieuadev.wpengine.com

Good luck with your pool and spa cover purchase,
