Re: Pump in basement
This might be a booster pump to provide extra pressure to the faucet. Is it an outdoor faucet? Perhaps the normal pressure wasn't enough to adequately run a sprinkler, so the booster pump was installed.
Another possibility is that is an irrigation pump and the pipe going into the floor is a well point. It may also have been installed to lower the water level under the floor to keep it from flooding.
Here's a test: find the main valve for water coming into the house and shut it off. Then open that faucet. If you still get water out, then it's not a booster pump and is probably an irrigation pump.
