Fluval A20061 X06 AquaStop Valve

Great replacement for my leaking valve on my 306. If you have to replace yours, I suggest ordering the o-ring for your filter at the same time. 2 birds 1 stone kind of thing.

Perfect

Works

Arrived quickly. Push the valve assembly firmly into the seat and youll never have to worry about the locking lever breaking off. It will actually lock itself in place.

Fluval is a great filter and this part was easy breezy to install.

Worked great as it should

excellent

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.

does what the old one faile to do
