RV park sewer connection issue

[Tommie]

We are on our maiden voyage with our new Eagle HT FW and ran into a small issue hooking up to the RV park sewer connection. Their connection is in a depression with concrete around it. When I screw my sewer connection down in the pipe there isn't enough clearance to install my sewer hose. It hits the concrete and want connect.
I was wondering if anyone makes an extension/riser that can be screwed down into the park connection that would give enough clearance for a solid hookup? At this point in time, my wife just stands there with her foot on top of the sewer line so it won't come out and make a big mess.
So far the new FW is working great. No issues in two days! [keeping fingers crossed]

Get a rubber donut. Connect you elbow, slip the donut on it and push down tight.

Thanks Grumpy! Never though of that. RV dealers carry the donuts? I assume they are all the same size.

Yep and many campgrounds have them in their stores.

Thank you sir! I'm learning slowly but surely.

The rubber sewer donut is required for each camper at some RV parks.

Camco makes an inexpensive one;
