Black Tank Flush
How long do folks normally run their black tank flush?
Forum Discussion
In one of the informative videos the tech showed how the tank should be flushed, then the valve closed to refill the tank, then flushed again and repeated until the water is reasonably clear. We have a clear plastic fitting between the RV piping and the hose to make it easier to tell the status of the water. I've repeated this 3 or 4 times which is better than just letting the water run.
