Thank you for the responses. I do my best to thoroughly flush all my tanks whenever I take my rig out. I’ve never had a problem prior to the malfunction of the San-T-Flush system. I will continue to seek resolution for this clog problem.

Question for WRKNRVR; Why do you recommend closing the drain when you see solids? Is there a reason why you would not want them out of the tank? Perhaps I am misunderstanding your comment.

Thanks for the input. This time out, we are using an ample amount of flush water as suggested; we will se what the effects are when we dump this time. Historically, I have always flushed the black tank first and run it out of liquid and solids, as viewed through the clear elbow. Then I close the black valve and drain my 2 Grey tanks as I refill the black tank via the San T Flush valve. Finally, I re dump the black until she runs clear. I might even have to keep the San T Flush running to achieve that. Before I disconnect my sewer hose from the dump connect, I flush it with fresh water. This has worked well until the last 2 times out.

Is it advisable to use an enzyme product like Rid-X I your black tank to break down solids?

G’day, I have a 2004 Forest River Wildcat 27RL 5th wheel TT. There is an external “San-T-Flush” fitting that is used to flush the black water tank when dumping. The last 2 trips out, I connected the hose to the fitting and the water would not flow. Normal water pressure but no flow. I don’t know where the problem lies; has anyone else had this problem? Does anyone have a possible solution? TIA
