Fluval A20061 X06 AquaStop Valve

The red latching mechanism that locks it to the filter is cheap and easy to break. It works fine, but be careful because once its bent it never straightens out and each time you lock it itll bend out of position and youll think youre going to snap it off. Shipping was good and no defects.

After a few years my 406 canister developed a leak right at the Aquastop valve, specifically at the flow control lever. I lost probably 5 gallons of water into my cabinet and carpet overnight before I discovered that the valve was leaking. Oddly, the valve only leaked when the flow lever was set to anything more than about 75% -- so I reduced the flow until I could get a replacement and the leak disappeared in the interim. The locking mechanism and flow control mechanism on the replacement feels tight. So far its working as expected and hasnt developed any leaks, but Im only a week into use. Its unfortunate that this valve seems to be a relatively common failure point for the Fluval canisters (as well as the impeller assembly). The replacement went in right in the place of the original, but took a bit of wiggling and fussing to get it to seat correctly the first time. One difference between the original and the replacement is the red compression nuts. My original were hex-shaped and could be (if you really wanted) gripped and tightened with a wrench. The replacement is knurled. Presumably this stops people from over tightening and snapping them.

This replacement product is exactly like the original part that came with my Fluval filter. Unfortunately I broke a piece of plastic off the original, necessitating the need to order a replacement.

Received this a day or so sooner than expected. I wish that this part was sold locally, but aside from that, everything is great!

Good quality

fit my filter but the handle is so easy to break

Was just what I needed pump is working great!

My original valve was leaking water from its side and the replacement fixed the problem. The levers also seemed much easier to use. Overall, EXTREMELY satisfied!

Muy bueno

Showed up earlier than expected. Has been installed for months now and has worked without error. Very satisfied. Thanks!
