I have purchased an older home in south Texas and it came with an older pool. The former owner had died and I purchased the home from the estate so I have no access to historical information on the pool.
The in-the-ground pool is about 12,000 gallons in volume. This pool does not have a screened enclosure and it is directly exposed to the sun for the majority of the day. Temperature here has been in the high 90's, the humidity has been in the 75-80% range and the wind blows here almost constantly at 15+ mph. I have tried (multiple times) verifying that the water loss is from evaporation and not from leakage.
I have noticed that the pool has a high evaporation rate (based on my experience from my former central Florida pool). It is not unusual for this south Texas pool to drop 1" in a day.
Is there anyone on the forum from central or south Texas that I can compare their evaporation rate to mine?
