Super easy to replace, great value!
I've always hated when something on my Waterpik gives out and I have to throw the whole thing out and buy a new one. Now that I've found that there are easily obtainable  replacement parts, I was able to revive my 7 year old WP with this fairly inexpensive replacement part and was up and running in just a few minutes. It only took a small Phillips screwdriver and about two minutes. EASY EASY EASY
