so I came home today to a dead sump pump. Sad. It is a Jebao DC Marine Aqua 6000. It usually runs on full speed. This pump is $101 on Amazon or I can get one double the output for $140. A couple questions ... If I get the higher pump and run at half speed will this increase the lifespan as opposed to running full speed? Do you recommend any other pump that will give similar results for a decent price? I have a back up pump that I'm rigging up but I don't want this to be the permanent solution!
