The septic hoses on my boat became clogged the last day of vacation, I have dismantled most of the floor and I'm going to replace them all. It's a literal shit show of a job...
Yeah that does sound fairly unpleasant... Nothing you could try to flush with a pressure hose? Or is there a chance of literal shit bursting out at the seams?
Well, apparently urine and salt water will eventually create some urine stone that you need to use some sort of acid or heavy vinegar to dissolve. That is not compatible work aluminium tanks. And you should really change the hoses every 10 ish years as they start to smell. It appears to be time for that, so I just have to bite the shitty apple and replace them...
