So I thought our pump was going bad, Saturday it made some unusual noises like a coke can full of marbles being shaken, so I opened up the crawl space (i don't have a basement) and trekked on over to inspect. Looked ok, sump container was about 3/4 of the full but no other water than what was in the collection sump. I tapped on the float (I also turned off breaker to make sure I didn't get shocked) and took measurements so I can go get a new one. I came backup and flipped the breaker back on and all of a sudden it was back to normal. The sump ran for 30 seconds pumping out the water (I can hear it from the next to breaker panel) and it sounded normal again. It ran 5 or 10 more times for about an hour or so pumping a little water. after about an hour it stopped, since it wasn't raining anymore I assume it's empty or empty enough that it won't need to run until it fills a little more. So should I get a new one or let it keep on? It's 14 years old so how long do these things last. Thank in advance for any input. .
