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

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 was exactly what I needed. It was easy to replace and fit perfectly. Thankfully it was also very sturdy because UPS completely crushed the box but it still works great with no damage. It arrived quickly also.

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!

Excellent replacement hose for waterpik. I've had the waterpik for probably 6-7 years and it works great but the hose finally developed a small pinhole leak. This replacement hose fit perfectly and works great. Great price as well.

I have bought my trusty waterpik in 2019 and I have used it probably 300 days a year. I love that thing! And in order to keep it clean and o mold gathering anywhere, I replace the hose and handle part yearly. I’m attaching a photo of the moldy looking thing that’s inside the base of the handle. Gross. This is an easy and cheap replacement for my peace of mind.

Works like the original! Doesn't fit as well in the holder, but it does fit. And saved me from buying a new Waterpik.

Almost perfect clone of the OEM replacement. Includes screws and a replacement flapper valve. The old valve was deformed and there is no documentation but installing the new valve restored the pressure that I felt had decreased over the years.

Works ok but hose is a littler larger than the original. Because of this it has lost some pressure. It did fit perfect and easy to install.

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.

Works as it should, and fits well on my unit. Only downside is that the bottom is not a soft plastic like the original part. The original part had a silicone-like bottom to it so that it would hold in place on the unit. Without the grippy plastic, it doesn't stay in place like the original part, but it's good enough!

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.
