Sorry to hear no fast drainage success as yet. The other way to look at it is probably that the real purpose of the AAV is not for sink drainage, but rather to prevent the sink P trap water from being siphoned off when other water devices/drains are being used in the coach. So maybe the odd shape of the grey tank is a contributing factor (for easier blockages) and I am wondering if just using a small diameter flex hose as a snake is adequate to make sure the drain pipe is totally clear. What about trying a proper plumbing snake?
