Fluval A20061 X06 AquaStop Valve

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.

The product was received broken. Not happy at all.

Works great, this saved my 4 year old fluval. I had replaced the pipes with just some clear tubing from the local home improvement shop and had them clamped on really tight which caused the spots to shear off with age and wear. This part saved an otherwise good filter.

Arrived on time. Worked as advertised. Very satisfied.

As usual, they work great, for a while, and then they go South. Im gradually switching over to different filters because of all the parts you have to continually replace on the Fluval filters.

Thanks

The valve starts leaking after a few maintenance cycles. Its very annoying and poorly designed.

worked as expected.

Fits perfect. It works great on my tank
