I'm trying to understand how the ejector pump is being used in the building I'm currently helping manage.
The building is 3 stories and there is a garden/basement unit too. The garden unit was built approx 10 years ago (although the building is a century old). In the garden unit there is a sump pump and an ejector pump.
The owner of that garden unit is telling me that the ejector pump is used for the entire building. But is that even possible? My understanding is that it's used to pump water/sewage up out of the basement level only. The units above ground would not need this.
But when I look at it, there are 3 tubes going into the ejector pump hole through the lid. One is the vent, one is actually pushing the waste, so what's the third one for?
