Well, like any other responsible pool owner, I am always checking the water level in my pool, so my strainer, and filter operate perfectly.
I notice the level going down a bit, check the weather forecast for rain and see that they are predicting typical summer time patterns (a pop-up shower forecast for the afternoon) with less than 1/5" of rain forecast for the next week. So I top up my water in the pool (leaving a bit for the rain that MAY come by).
The next day... 3+ inches of RAIN!! Forcing me to drain some of the water out of my pool.
This has happened to me BOTH times so far this year.
So I am convinced that I can indeed make it RAIN!
