Narrative:
When working this MEL I discovered debris under the lavatory dump valve and removed it. There was no damage to the valve and it operated properly. No other discrepancies were noted and I svced the lavatory and found no leaks. There is an airworthiness directive out on this system, and a task card should be used when repairing this system. The task card was not used in this case, hence the report.
