I'm looking to replace my sump pump because the last rain storm showed that my sump pump couldn't handle the amount of water. It ran continuously for about an hour or two with the water level still rising.
My basin is 13" diameter at the bottom and 22" high.
I was looking at a Wayne pump and all of them point to the same documentation: https://www.waynepumps.com/wp-content/uploads/woocommerce_uploads/2018/10/600002-001-D.pdf
It states that a minimum of 22" height is needed.
My question is why is the 22" height needed when the sump pump itself is 11.5" high by 9" wide?
