Pduggs 78 Posted April 8, 2021 Hey Scotty, that looks very nice. If I understand your pics correctly, you replaced the old box Sanicon with the newer version. It looks like the waste drain exits under the coach and is permanently outside the wet bay...so all you do is attach your waste hose. Did you drill a hole in the floor? I have the old box Sanicon and it has worked well, but does the newer version perform better? You still have the grey water bypass right? Link to comment
