@whirly omg, that reminds me when i had to clean out the toilet of a old sailboat.
They all are refurbished in a way that adds a plumbing system with a powerful pump, so the toilet getting clogged will lead to the pump having problems and it absolutely should never happen.
but somehow, someone managed to clog it, probably by not being able to adjust to a low toilet paper lifestyle.
so i put on some gloves, got my hands in there and was able to break it up thankfully
