Need some input here. The Boss Lady and I have been having a disagreement. When we go to bed at night should the water pump switch be left On or Off? I say Off, just in case something breaks loose and leaks while we're asleep. She says On so she doesn't have to go looking for it in the dark after one of her midnight trips to the loo. So what's the consensus?? Off at night or On (and take your chances)? Thanks.
