When a typical swimming pool that does not have an autofill is leaking, it is pretty noticeable considering the water level will drop. Pools that have either manual or electronic type auto fill devices will keep filling the pool even though the pool may be leaking.
Because of water conservation issues, it is rumored that some cities might ban the use of such autofill devices. Cities in Travis and Williamson Counties including Austin, Lakeway, Cedar Park, Georgetown, Leander and San Marcos are just to name a few.
If consumers who have an autofill on their swimming pool would only shut the swimming pool equipment down for 1 day every 2 months, many of these problems would not exist. Normal evaporation rates vary from different areas and different terrains. Example: a house high up on a hill in Lakeway will usually have more evaporation due to wind than a typical home in Austin.
Either way a good rule of thumb is that a typical pool should not lose more than an inch of water max due to evaporation. If your pool is losing more than these rates you need to call a qualified swimming pool leak detection specialist who specializes in swimming pool leak detection and repair like Austech Pools.
