Replacement Hose & Handle Parts for Waterpik Aquarius Water Flosser (WP-660 & WP-670 Series)

Fit perfectly, and includes the little flap gasket it apparently needs. No instructions - but here is all you need to know. - unscrew the old hose/wand assembly from underneath, then get a flat head screwdriver and carefully pull out the little flap gasket at the bottom of the hole you just uncovered. Then clean up the hole with a paper towel and install the new gasket they give you. It has a flat side that needs to line up because the bottom of the hole isn't actually completely round at the bottom. Then install the new part. They give you new screws, but I simply recycled the original screws that I knew fit correctly. For someone reasonably handy, you can replace the hose and wand in less than 10 minutes. It seems to be identical to the OEM part as far as I can tell, and the little clear tips click into it the same way. It doesn't leak at all. It is certainly a lot cheaper than buying a whole new one.

It appears to be a quality product but the "O" ring does not seal properly. The screws were inserted carefully and fully tightened but when the pump is running, it leaks. I would estimae about 1 to 2 tablespoons of water accumulate on the vanity top during use. I have re installed it once and will try again. If it still leaks I will return it, if I'm still inside the "return window" I just installed the replacement hose and handle. I carefully cleaned the installation site, put a tiny amount of olive oil on the O ring to help it seat... tightened the new screws and filled it. NO LEAKS. I consider it a perfect replacment. I change my review to 5 star

works fine and the replacement procedure is simple and straightforward requiring just a philips head screwdriver

This saved me a lot of money on a new Waterpik even on Black Friday. When I figured out how to install it, see below, it worked better than the original, and does not leak. That was the problem with the old one. The water pressure seems greater so dial it down at first! The button on and off on the handle is helpful. It seems durable However, I open it and there are zero instructions. Not sure how hard it is to print up a small sheet or even something on the back of the box instead of graphics. One half point off for that. Then what do with the extra fabric “gasket “ ? I assumed it went on the pump that attached to the machine even though it looked like it would block water. One half point off for that. I should not have to rely on the opinions of reviewers to get basic information, which is what I did. In sum, great price right now, does the job well, and installation is easy actually, so I do recommend it, I just wish someone wrote a small guide. AI can do that for you!

The hose on our original Waterpik broke in half. Bought this replacement hose for our Waterpik model "WP 110W. Was very easy to replace. Looks and works like the original. The handle may be just a tad bit shorter and narrower but hardly noticeable. Picture on left is the new hose. On the right is the broken, original hose.

Perfect replacement for my waterpik. The original hose developed a cracked and water leaked everywhere. The motor was still good and I decided to replace the hose and head. Works perfectly now

Perfect replacement for original WP 660C hose and Handle when original hose broke off and couldn’t be repaired. New hose appears more flexible and hopefully will not harden with age. Very easy to install the new hose and handle.

This after market replacement arrived quickly. I couldn't find it in the matching gray color (its white) but it attached easily and didn't leak. My only slight gripe is that ithe handle easily falls out of the holder unless one very carefully sets it back in. Some have complained that it isn't has strong presure wise. Since I use mine on a higher setting i really can;'t tell whether it is different. Sometimes I think maybe it is and other I can't be sure since I neer paid that much attention. I use setting 8 and otherwise it works fine. Waterpic wanted like 20 bucks + shipping so this was a better value.

Apparently the hose on these Water Pik units often spring a leak after awhile. This replacement was a perfect fit. It took less than 5 minutes to remove the old hose and install this new one. Works just like new!

I have a "A box" and it fits. Works great when you take the screw out of the attachment area. Lol. Works as described when you make sure you don't have an extra screw in the way.

Happy so far. Bought this to replace my OEM one. Great price! Works just as great.

Much cheaper than replacing whole waterpik. Easy to change. Would purchase again.

The item I received is dirty. I can see dirt particles over the hose, the tapes, and the handle. Very nasty. I hope I will get an refund.
