Replacement Hose & Handle Parts for Waterpik Aquarius Water Flosser | Compatible with Waterpik Water Flosser WP-660 WP-670 WP-100 WP-300 WP-900 Series Oral Irrigator, Plastic Handle, Slide Switch

Very pleased with the performance and quality. I was reluctant to purchase not being an actual WaterPik replacement but it was a perfect fit and works just as well. I have a grey unit and chose white but it’s just fine. Saved money and shipping!

This replacement wand works very well and is easy to replace.

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

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.

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.

Easy install and a good replacement

I was worried that buying off brand would be a mistake, but, this replacement has been working great! It's just as good as the original.

Hose on my Waterpik WP-150 snapped the other day, so I used my Prime Amazon account to get a speedy replacement. First up – this is clearly NOT OEM replacement, so anybody saying that is non-stop spouting – just like this non-OEM part. I was able to replace screws and filter just fine. The handle does not fit flush in the holder. As I was filling the reservoir, I realized the handle was spilling water over all over the counter. Ah, second up – there's no on-off switch on the handle; the default mode is to have water running all the time in accordance with gravity. So you have to be careful to always have handle pointed up. The switch on the handle is a shut-off switch only and needs continuous application to keep water turned off. Default mode is on. I'm only going to rate this three stars since I've only used it once. Wouldn't hazard a guess as to its longevity, but wouldn't be surprised if it quit working soon. Hose is softer plastic than original.

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!

Exact fit easy install. Looks feels and works exactly like the original. Highly recommended.

This replacement hose works fine, not like the first one I bought, which leaked all over. This one is easy to install and the water makes it all the way to the end without leaking. The off switch doesn't keep water from leaking out the end if the wand is upside down, but it works if the wand is upright as it is when it is in your mouth. I'm satisfied.

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.
