Was a little frustrated at first because no matter what I tried it leaked right where the pipe from the wall and bracket meet. Followed the instructions and didn't use pipe tape. It also says to hand tighten only. A quick call to Waterpik customer service solved the problem. Simply use bar soap and coat the threads of the bracket and pipe. I did use a wrench to gently tighten and no more leaks. :) Also had a little trouble removing the orange water flow restrictor but needle nose pliers solved that problem and I was able to pull it out.
