We are happy to send replacement pumps however often times you can get it working again. What happens is that air get caught in the bottle and / or pump. Follow these directions:
Once the pump is screwed on, place your thumb over the mouth of the pump tightly, where product comes out.
Press down on the pump as if you were dispensing product while your thumb covers the opening. This forces the air trapped in the neck of the pump, out. Voila, problem often fixed.
Please let us know if that doesn't work and we can send you a new one.
