I bought one of those hoses with a spinner on the end at WalMart. Works great. Especially if the sensor is not reading properly after dumping. Just hook up the hose and stick it down the toilet and it seems to clean most of whatever is still left behind. I do not back flush any more with this tool.
I leave my black tank valve shut until the tank is full before dumping even when I have full hookups. Leaving the tank empty just encourages dry areas that will not come clean as time passes.
Plenty of water is also part of my regimen when flushing. No chemicals at all.
I do not see how anyone can have odor problems with a good seal.
