I am in the Keys..in Marathon..which is like a third world country when shopping since Irma. Will probably have to go online to get a pump.
I read somewhere that you can open the tiny little drain at the bottom of the cylinder if you need to empty out some water, but the only time I use that drain is when I am cleaning the filter. It did not sound like something I should do while the pump is operating!
At any rate, the water overflowed the pool last week, over the next few days the level only slightly receeded, new rainfall overnight brought it back to the top of the tile right at the line of the rust colored coping. We will be getting up to 4 more inches of rain tonight and tomorrow.
