Query: water doesn't come out

I just got it, per instructions, tried to prime the pump and....nothing. the water doesn't come out. I called the company, they said that I need air extraction pump or something like that to remove the air from the lines. They are going to send it to me -- will see. Bottom line is it didn't work out of the box as was the case with the other two reviewers. Apparently, when it works it's great (per the 3rd reviewer)so I'll keep you post it. I don't rate it because obviously I don't know how good it is when it works.
