I always use RV toilet paper and also use quite a bit of water to flush. I have never had a problem. Oh, I also backflush for about 2 minutes with valve closed, then drain, then backflush for 4-5 minutes and drain and if water is still slightly off color, I do it one more time and usually it is clear then.

I am always at FHU parks and drain every day we move on and also every 3-4 days when stationary. One time I stayed at Chicago Naval Station and they had no sewer and the dump station was about 200-300 yards away so you had to hook up and move rig. That time I managed to get about 5 or 6 days before dumping.
