I remember a complete replacement kit for the Vent-Away plumbing system that was available for around 50$. It came in a smaller kit if you did'nt want it to vent-away and a larger kit for vent-away. Does anyone now who or where i can get this/these kits from? I'm not looking forward to rebuilding this for a long time after I'm done. Or is the old rubber gasket, seals, o-rings, and flapper replacement a better easier way to go? Thanx
