I have a 2017 Minnie Winnie and am having trouble with my black tank draining. I dont know if the issue is the gate valve outside that is stuck or what. I let it sit until; next stop about 150 miles. I thought whatever is stuck would work its way out. Before we left i put some chemicals down to include Happy Camper but still no go. I am thinking the gate valve is broken closed? If not I'll have to work my way from the valve to the tank. Any opinions? I am open to any ideas/as always thanks!

Open the toilet and look inside. Is there any water? Add water and drive around, to mix it all up real good. If that doesn't work, it's gonna get real messy. Run something semi flexible up the waste connection. Better have a few huge buckets on hand, or be right next to a cleanout.

What are you basing the issue on:
- If it's the pretty lights on the monitor, they always show up as full even after you drained.
- Do you hear anything when you open the valve?

Tank Flush

You can buy an adapter like this and hook up a hose. It water goes into the tank you are OK. If the water just flushes back out the valve is broken and stuck closed.

Get the model with the gate valve.

Go to Walmart and buy the reverse flush thing. It works good. If that doesn't work...oh dear...

You pulled gate valve “open”, nothing came out?
99.9% sounds like broken gate valve to me.
Start there.

The flush attachment at wallyworld works really good, and is reasonably priced. About $15.00. It also directs the stream straight back into the sewer pipe. Shoots about 25 feet.

Look from under neath to see if the slide valve/gate is opening.
