Black water tank flush

We purchased a 2019 31 SE Freedom express and it doesn’t have a black tank flush on it. Has anyone ever installed one on this model before? It has an enclosed underbelly.

welcome to the forum its a great place to get your questions answered. I did not think any newer rigs came without a black tank flush with that said rig have survived for years without one. Some options you might consider is the Camco swivel stick I used this on my class A worked great without having to cut into the side of the rig and tank to install a clean out kit. JMHO about $21 for the stick or 39 to 150 for tank flush kit.

Not on that model, but I had a service center (not a dealer) install one on my Sabre years ago. Cheap part but they charged 60 or 90 minutes for labor so it got expensive. That had a covered underbelly and they had to remove a portion of it to get to the tank.

Not sure if this is sufficient for you - but worked for me. I used the stick I think they referenced but my gauges were always suspect. Bought this doohickey and tried it for the first time, and it worked well.

I once had an older coach with a defective flush and used this same device. It works well.

That's good for rinsing out the discharge tube. But the water will never reach the tank itself.

You need one with a built-in valve.

IWC, what is that extra, threaded piece? I’ve had a Flush King for many years… bought from the original FlushKing company but I’ve never seen that extra connection.

The stick is also called a tank wand. Because it is hand held, you can move it around and make sure you really get things clean. Google GEO method if you haven't already. Calgon water softner eliminates a lot of problems.

I honestly don't know. I just did a quick search and that's what came up.

My best guess is that it's a plug for the port where you connect the hose. So if you want to dump without the hose connected, it won't squirt out the top.

It's listed as an anti-siphon valve.

EDIT, I may have been wrong. Here it's shown in use:
