We recently had a tremendous rain overnight and all three pumps in the basement failed…so we got a ‘nice’ flood downstairs.  What is insane is that the back pumps – there are two – one was on a marine backup on a car battery (in case the power went out) — the battery, though hooked up to a charger — was dead; must’ve been old.  The other main electric sump pump was completely dead, so I replaced it.  The other front pump seemed to be gunned up as — you can see in one of the videos below — once I shook it it began to work as it should…. too late.
