Gray/Black water flush leak

New owners of a 1999 Airbus. When trying to flush out the gray and black water tanks after emptying, we noticed a good leak coming from underneath outside the bathroom. Upon further inspection inside the MH, the storage area under the bathroom sink was wet. Any ideas?

Sounds like the 'anti-siphon vacuum breaker' on the black tank flush system has failed and is allowing water to pour out top cap .......


DO you see something like this device in the bathroom sink cabinet?




Flush water comes in thru bottom line/connection then goes out to tank nozzle thru the side line/connection
Water pressure is suppose to close off top section which is open to atmosphere
If it doesn't then big leak source inside the RV

Old Biscuit is pointing you in the right direction. It'd also possible the housing for the anti siphon or a fitting is cracked. Best way to check is get a good view of the valve and have your wife turn on the flush. Be sure to use a flashlight as small cracks will often not leak fast enough to make it easy to find the source of the leak.

Good luck!

Hey Old-Buscuit, thanks so much for the help. We did a test on the valves and sure enough, the valve on the line for the black water tank was bad. We've ordered a new one. Thanks again!!!!!
