Hello I have a slight drain problem with my 2013 Flagstaff 8528 RKWS. When you flush the stool you get a air bubble before the stool flushes. I assumed that a vent on the roof was obstructed so I checked them and didn't see a problem, it did not act like this the first three camping seasons. This is the first problem we have encountered and hope some on has a suggestion. Thanks Rocketick
Thanks 5picker, the problem occurs tank empty or any amount at all. It did not act this way until first trip this year. I still think its a vent problem, I haven't found where the vent pipe on the roof tees' Into the large drain pipe that I can see in the basement of the unit. I was hoping some one else had experienced a similar problem and could offer a little guidance thanks Rocket.
I was on the roof and looked under the vent caps. I could see rite down the pipes, there are two up there every thing appeared in order and clean. Does any one know how and where the stool vents? Thanks Rocket.
Mine did this for the first time yesterday. At first it burped then the water went down then it got to where the water barely went down. I turned off the water so I could shined a flashlight down the stool to see a blockage of about 80%. I poured some water out of a pitcher down it to clear it out and that solved it. What started it was more solids then liquid since we had only been setup for a couple hours.
