When I was getting my motorhome for it first trip, the Toilet water would not drain. I flushed out the blackwater tank two or three times before I put the rv up for the winter. When I went to check out the system for our spring trip, the toilet when I filled it up would not drain. I tried snaking a garden hose down and that would only go about 10 fit and stop. What could be blocking the toilet water from going into the black water tank? Right now the only remedy I have is to take it into an RV Service center and see if they can fix the drainage into the black water tank. Any idea what the problem could be or do I need to take to an RV Service center to fix.

Read the comments on your previous post, you'll get some ideas.

I tried those post and they did work or apply. So I thought I would clarify that the clog was during the spring start up and not during usage. The water is clear indicating no poop or toilet paper. I guess I am left with taking it into a RV repair service to solve the problem.

You will get the same answers here. You will also get better information if you answer the diagnostic questions that were asked to learn more about the problem.

For example, what tank level does the black tank level gauge read?

I solved the problem, there was a switch on the wall I had not turned on the pump that takes the water flow through the grinder and into the black tank. I have flushed the toilet several times with the switch on and there is no back up of water into the to toilet and flushes normal. Something so dumb that I overlooked.
