My basement flooded during the storms of last June here in the Midwest. My sump pump simply could not keep up.
I am going to install a second sump pump in case this should happen again. I've decided the back up should be battery powered in the event of a storm + power outage.
Here's my question: Do I need a separate line out of the basement for the second sump pump or should I just join the two pipes and run one line out?
I have 1 and 1/2 inch pipe with the current sump pump. If we had a repeat of the tremendous amounts of rain of last spring, would the size of this pipe be enough to allow both pumps to run at or near their capacity?
Thanks in advance for your advice/opinions.
