i just installed TWO tornado's this week....beats the hell putta hauling a hose inside & risking a wet interior !
In my particular install i could not get high enough at the back of the tank, so i installed them in the side - I've never had an issue with tank odors (but then i throughly rinsed my black tanks by sticking a hose down the toilet).
I added some quick disconnects & have a short bit of hose that i connect to the water/rinse source....which makes it easier to connect the hose to the tanks.
the QD fittings make it easier to put the "cap" back on too.
my only regret is that i should have done this years ago - but was too apprehensive about putting a hole in my tanks.
