I live in California and want to keep using my pool while minimizing water usage.
In the winter, I uncover the pool and let the water level fall due to evaporation. When we are lucky enough to be getting some rain, I drain the pool a few inches. The water level is below the skimmer which must be turned off. My skimmer isn't much use anyways due to poor design as I have been told and in the swimming season the pool is covered when not in use making the skimmer irrelevant.
What problems could occur if I let the water level fall all summer? I will probably have to keep it above the inlet ports as it looses siphon when dropping below them. (I might experiment with tubes from the ports into the water to solve the siphon issue). Could I experience damage to plaster which is exposed to the summer sun? Are there other problems that could occur. The pool is actually deeper than I want and lowering the level would have other advantages besides saving water.
Thanks to all who take time to answer.
