My new WP-100 would not prime initially. I filled the reservoir with water and placed the reservoir in the unit and pressed the power button. The unit started running, but no water was coming out not the nozzle. I tried adjusting the pressure dial but still no water coming out. In removed the reservoir and reinstalled it with the same results. In finally pressed down on the reservoir and then unit primed and started working. This is my 2nd Water Pik, the first one worked fine and lasted several years, disappointed in this new one tho.
I would recommend this to a friend!

I love my new waterpik. I have never used one before, but now I am glad I have started. The cleaning along the gumline and between teeth feels really good. After brushing and flossing, food particles still exist. The waterpik flushes everything out. What a great , useful product.
I love the functional part of the product, but I can’t use it every time I need to because it is so loud. I have a roommate and neighbors in my apartment.
My dentist REALLY wanted me to get a Water Pik and this model was the one she demonstrated at the office. It’s reasonably priced and it was readily available.
