For your pool
What this means for your pool
-
Digging
Soft bedrock is typically about 18 inches down in the main soil here, over limestone. Ask every bidder how they price rock excavation before you sign. [3]
-
Slope and views
The ground within 5 miles rises and falls about 547 feet. Sloped lots often need retaining walls, and the same slope can give a pool a view. [1]
-
Plaster and scale
The city's water averages about 321.6 ppm hardness, which counts as very hard (over 180). Hard fill water leaves scale on tile and plaster, so test calcium hardness when you fill and top up. [7][14]
-
Covers and top-ups
Open water here loses about 53.3 inches a year to evaporation. That is more than the 37.5 inches of rain and snow a year. A pool cover cuts how often you top up. [6][5]
-
Freeze protection
About 40 nights a year drop to 32°F or below. Run the pump through hard freezes or fit a freeze sensor, and protect exposed pipes at the equipment pad. [5]
-
Fill timing
Your water supplier can limit outdoor water use in a drought. Check the current stage before you drain, fill or refill a pool. [10]
-
Filter care
Ashe juniper (cedar) sheds pollen from mid-December into early March, and oak leaves drop into the water. Empty skimmer baskets and clean the filter more often then. [13]
-
Critters
Scorpions, rattlesnakes, copperheads and chirping frogs all live in this part of Texas. Keep the equipment pad clear of clutter and check before you reach in. [9]
