We recently put a new water pump in. We have had 3 of them because each one has seemed to last a week and then stops working. This last one has been in for about a week and a half. Today it cut off 2 days and each time after a few minutes it comes back on. This last time I got in the shower and it had a metal smell. When I got out I also noticed the toilet water was a cloudy color. What is it, and is it safe?

Are you talking about a well pump? The only way to tell if water is safe is too have it tested in a lab
