Took out old sump pump pit, dug it a little wider/deeper. replaced the pit, and added dual sump pump + battery backup. Dug a whole new pit on the other side of the basement.. and inserted a new pit & single sump pump with batter backup. Wow is all I can say. They were on time, very professional, and answered any question I had. They arrived at 8:30 and were there until 5:30. They ate lunch while they worked… This was a lot more manual of a job than I expected.
