The other day I was washing my hands inside my trailer and I thought I'd check to see what the level was at. I checked the grey water level and it said full.
I thought wow thats weird I haven't used the water that often.
So I hooked up my 27gal Thetford portable waste tank and drained the tank.
After about 15 mins I shut the valve off. I pulled the portable waste tank and it felt very light.
Thought ok there must be gunk or something that are hanging up on the sensors.
I drained the portable tank on my lawn and seen some black slime substance.
I thought hmmm, maybe I need to fill and drain the tank again.
I did so and more slime stuff come out.
Any ideas as to what this is and should I be worried ?
