Need help! Had water all day and then at 11:00 at night we had no water at all don't know why doesn't sound like any things is running and we had a new water system put in about 8 months ago. Don't know if it is the water pump or something else going on. Could you please help...

The first thing to check is the power to the pump. Is the breaker blown? Did the pump lose prime? Give me something to work with here. Let's have more details. Back to you. Tom

Great advice from SB. Also, is your pump above ground or in the well.
