Hey thanks Emery, that's the best advice for a poor relation like me having just one black tank and no mascerator can get.
After emptying, should I leave the gate valves on the black tank open? (I have two; an extra one with a cover at the very end of the discharge pipe)
I ordered both of the kits you recommended, should be here on Thursday. The access to the tank mod you did looks like just the thing, there sure ain't
a lot of room in there to work beside the toilet in a wet bath unit like mine. I might just do the same mod as I don't use that lower cabinet for much
and with the mod you don't lose any space anyway, right?
As far as the toilet goes, do I need to run the pink through to a flush (so I can see pink in the bowl) to make sure the toilet lines are protected?
Cheers
Larry
