Hi SGT! Mike in WA state: I dont know how to ask a question yet in the Forum. Bad plumbing problem here. In our Silverback 29lr the toilet is not draining. Have tried most usual methods to unplug. RV repair guy says we have a stuck or broken wastegate in line. Ridx does seem to loosen jam or the wastegate is partially open, if this is the problem! I use a Shurflo macerator to pump to empty black tank as there is a rise to the septic tank. Can you advise or know someone who does ? Appreciate any help.
