I would like to thank Valterra for NOT redesigning the 3" wastegate over the years. I was able to fix my 1999 Fleetwood with a leaking and broken bypass gate system without having to replace the entire system. I unscrewed the 3" flap and reused one side of the bracket that was glued to the tank side ABS components. On my new build I greased and mounted and reassembled on a 20 year old bracket. Reusing part of the original assembly saved me a lot of time and money. My sewage system is no longer leaking and is working better than ever in my 3 years of ownership. Thank you for keeping a great design and not "changing" for the sake of change.
