This may be dumb - but what is the process you use for flushing out the black and gray tanks?
Some black tanks have a tank flusher installed. It is a nozzle inside the tank and attached to a water supply that ends at a hose connection on the side of the trailer. The recommended process is to open
the black tank drain - connected to a dump, of course - and then attach a hose (one not used for potable water) to the flusher connection. Turn it on and let 'er rip until you are tired of it. Grey tanks don't usually have a flusher attached, and don't need it as much as black tanks. One thing we usually do is after we dump the black tank is we add two to four full toilets full of water to the tank. The sloshing that occurs when driving helps to keep the crud from sticking to the tank walls. The amount of water added varies as the perceived cruddiness of the tank and how long we might be boondocking at the next stop.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
