INTENT Owners...

Did yours come with a hose fitting for a black tank flush? It says in the brochure that it's a standard feature... and yet my 26M doesn't have it.

This tank REQUIRES a good flushing.

I've been using a clear elbow at the drain with a hose fitting, but back-filling all the plumbing and then slowly filling up the tank just doesn't cut it. There needs to be a fill, or a Tornado would be even better, on the tank itself. This way the tank would fill and drain properly. Well, better anyway.

Anyone else missing this feature?

I've contacted Winnebago, but no reply yet.

This is the worst black tank design I've had. The tank has a large footprint, shallow height, and sunken in the center - rather than an angled bottom that naturally forces everything towards and out the drain. When you first open the drain, the mighty Mississippi river is unleashed, but then it just turns into a brown, trickling stream.

The drain plumbing is in the side of the tank, so anything that may have been "dumped" into the tank has a tendency to sit there at the center low point. It's been taking me 2 full, back-filled tanks to get the drain water clear. What's that - 70 gallons?
My last RV took half a 5 gallon bucket poured into the toilet to flush it clean. Then I'd close the drain and add the other 1 or 2 gallons with the chemical pod. Done.

The toilet doesn't sit directly on top in the 26M. The drain makes a left turn towards the tank. And as far as I can tell, the outlet plumbing exits on the rear, center, SIDE of the tank, with a 90*, a 45*, another 90* before making ANOTHER 90* to exit through the drain hose.

Also, the days of just dumping a few gallons of water in the freshly emptied tank, along with the deodorizer chemical pod, are long gone. That amount of water just fills the long drain line and leaves the tank bottom dry.

End of rant.

I don’t have an Intent but have a Vista with a long, wide black tank without a flush connection. When I’ve emptied, I fill to 1/3 then dump again. Then, I’ll scientifically add water for 30 seconds, hoping that it’s enough to cover the bottom when level.
