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

This was easy to replace and is holding up great. The water flow is great and it was more economical than buying a new waterpik. It works as expected.

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

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.

After sifting through all the reviews for this as well as other replacement heads and hoses, I ended up purchasing this model as it had marginally slightly better reviews even though it was slightly more expensive. Installation was quick and easy, and it was completed in about five minutes. Now the true test was to see if the water pressure was at least equal to the original, and if there were any leaks as reported in the reviews. I asked my wife if the water pressure was similar, and she thought it had more, while I did not experience any difference. The attachment point was very firm and tight for the jet nozzle, and the on/off switch was solid while moving from the on to off position. I saw no leaks, and noticed that the tubing appears to be a little more pliable, and flexible than the one it replaced. It could just be that the old one had hardened with age, so I don't really know if that's true or not. I would rate this at least as comparable to the original, and would definitely recommend it to others.

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

After taking a chance on this replacement, I can confirm that it is compatible with my 10 year old WP-100 (or is it WP-100W)? When I received the box, I noticed on the back that it not only lists the WP-100, but also WP-250, WP-300, WP-450, and WP-900 models. Hope that helps those looking for a different handle. Why not just order a replacement listed for my exact model? My original handle only had a pause button, but I wanted the on/off feature, so I am glad to report that it has been an exact fit at the attachment. So far no leaks at all. The handle doesn't sit entirely flush, but it wedges into it just fine for overnight storage. The only design element I miss about the WP-100 handle is the positioning dial where you use your thumb to rotate the water spout. You can see in the photo that the replacement handle is so much whiter than my yellowing Waterpik base. I stopped using my Waterpik about 5 years ago, and after a less-than-stellar visit to my dentist, I dusted my Waterpik off and it worked for about a month before springing a leak. The brittle plastic was due, and seems like the weak point in these water flossing systems. The set also includes replacement screws and a filter, which also fit fine.

Aún no puedo creer que hallé este repuesto para mi water pick! Excelente material y fácil de instalar, recomendable para limpiar nuestra dentadura a presión.

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.
