2 weeks? Maybe someones not using enough water when they flush?
Or they have a very large Black Tank.

Wife and I can go 5 days MAX on our 38 gallon if we are very careful. By then we're either out of or very low on fresh water so...

Best measure I have seen for Black and Gray tank is the fresh water tank. If that is very low or empty, it's a good bet that the black and gray are close. (Unless you use the outdoor shower a lot)
