Amazingly, our basement did not flood despite our home being without power to run the sump pump for several hours while the ground was saturated with water due to melting snow and heavy rain fall. We were very lucky. The sump pump cycled on and off for a long time after the power came back on. It never used to run even in the spring. Now, with the rising water table over the last few years, we will probably be purchasing a battery backup in the very near future.
Have a great weekend!
