Threadjack alert: I owned a house in KC for 11 years. It had the same sump pump that came with the house; it was probably 20 years old. It had always worked fine and I never touched it.
We put the house up for sale and had it under contract, handing over the keys in 10 days. We get some pretty massive rains but everything is fine. The next day I go to pick up some boxes to pack and the wife calls - there is water in the basement.
I get home, the pump has failed. It won't turn on at all. There is probably an inch of water on the floor but the drain appears to be doing it's job the best it can (it's on the opposite side of the room). It's 8:30pm on a Sunday night so I scream to Home Depot to get a pump. Get it put in, I avoid electrocuting myself, it starts pumping out water. It was a sub-basement that wasn't finished but it did have old carpet just laying on the floor with no pad. The shelving was elevated a few inches and nothing was damaged other than the carpet and some luggage that was sitting on the ground.
I roll up the carpet, lug it out to the garage, put it on plastic bins, Febreze the hell out of it and fire up some fans. Stuck it back in the basement three days later.
I guess I should have put a new pump in sooner. Seriously, it couldn't have given me another two weeks after that many years?
