Check/Replace Your Tip Also
I read a lot of reviews complaining this unit leaks around the handle.  So I bought the original direct from Waterpik.  Put the one from Waterpik on and it was leaking around the handle.  So I tried this one from Amazon,  and it also was leaking around the handle.  To my surprise when I diagnosed why they both were leaking it was because the old tip was not making a secure fit.  I put in a new tip and the leak was totally gone.<br />Note compared to the original this one has a softer hose material.  Yes it does reduce the flow and pressure a bit compared to the original direct from Waterpik, but otherwise worked fine.
