Black Tank Flushout Tip
On Tuesdays, I write about technical tips and products.
Some higher end rigs have a black tank flushout. This is an inlet to which a grey hose can be attached to direct high pressure streams of water into the black tank to flush it out.
A hose should be hooked up to this inlet only when the black valve is open at the time of dumping. This is because, as some RVers have learned, leaving the inlet hooked up can cause the black tank to overflow, seep up into the toilet, and flood the rig with sewage. This could be caused by a valve failure or someone inadvertently opening a valve.
The convenience is not worth the risk; only hookup the tank flushout when using it!
