If it’s anything like a regular house sump pump (which i suspect it’s not, they should be way higher duty in a building like this), I’ve seen the pumps last 10-20 years without too many issues.
- koolba 5y agoThat depends on how often they cycle on/off. In brutal conditions of constant use, I’ve seen them fail after 3-4 years.
- MattGaiser 5y agoBut that would point to this being a case of brutal conditions with constant use. My real question was to try and grasp how much water they were pumping compared to others.
- cratermoon 5y agoYes, which is exactly the problem here. Those pumps should not have been in constant use. The fact that they failed so often means they were being run far more than would be expected under normal conditions.

- verelo 5y agoYeah, i imagine in cases where this is to be expected, the sumps themselves need to be much larger (or have more of them) and the pumps need to be higher duty and intended to move more water. Certainly exceptional, but i'd hope anticipated in the design. Our sump here runs all the time when it rains, but then it goes for weeks without moving any water (especially in the winter). When we moved into this house, the pump was broken, but there was also water damage in the basement. First thing i did was replace it and now its a common sound to hear the pump running.

- na85 5y agoI lived in a place in Ontario where the grading wasn't correct and my sump pumps were failing every 18-24 months. It would run for days after a heavy rain.
