    What happens to pump if water to house is shut off?

    Had some work done to a (currently vacant) rental house (600 miles away) this weekend. Turned out there was a water leak in a bathroom and water had to be shut off - for a few hours is our best guess. We are not yet sure if the handyman cut the water just for the bathroom or to the entire house.

    If the main water line to the house was shut off and the pool pump was running during this time, are we likely going to be looking at replacing the pool pump?

    There has always been a maintenance co to care for the pool, so we are pretty clueless.

    Thanks.

    Welcome to TFP!

    Turning off water to the house shouldn't have any effect on the pool at all in the short run. Eventually you may need to replace water due to evaporation, which will require water. Now, if they turned off the electricity for an extended period that would be much more of an issue.

    And this is because the pump, essentially, works from the water already in the pool, correct? And considering we lose about 4" per week (which is a venture we plan to undertake [sigh] in the next 2 months, that's another whole issue) we should be fine. But if it had been for several days without electricity, the concern there would be the chemicals and the water turning green. Correct?
    Thanks so much for your reply!

    Basically correct. Although even without electricity, you can maintain the FC and prevent the pool from turning green.
