Fluval A20061 X06 AquaStop Valve

Perfect

I bought 2 of these. I haven’t had any problems. If you don’t set it in properly and force them down will break.

Stopped the leak as soon as I put it on

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 has lasted longer than the valve that came with the filter

I received the part broken. It came in a bubble wrap envelope and the plastic piece was broken when the passage was opened.

Came quickly and fit right into my fluval filter. We were back on track to a clean title tank in no time.

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.

EZ to replace broken part on filter. no

Good quality .... no more leak.
