Fix Fluval Aquastop valve for 106/206/306/406

My Fluval 406 filter started to leak around Aquastop valve around 2 years after purchase. I could temporarily stop the lead by squeezing silicone grease around the rotating parts. However, the leak came back and this time I couldn't fix. But there is a way. You need silicone grease and plumbing teflon tape. I have to disassemble the white lever. In order to do that, pull the white level all the way up, then pull down the red latch to "close" position. Now you can pull out the white level from value body. Next, you have to slide out the rotating cylinder  by pushing to either side. Clean the cyclinder then apply dap of silicone grease around rubber rings. There are 4 rings. Then wrap each ring 3 times with teflon tape. Now you're done. Reassemble. No more leak!
