That still does not overcome plumbers rule #1 if point A is higher than point B. S##t runs downhill.

There is another thread here about the Flojet macerator pump.

Also known as the answer to your problem.. I've used one for that situation. The very model in the thread.

I've been at sites where the sewer tap is high, but never higher than the bottom of the tanks. The stuff still flows, and if what's sitting in the slinky is an issue just drain the hose hand over hand or build a bridge.

Bingo, just like a p-trap, as long as the bottom of tank is higher than cleanout... Just be careful when disconnecting the hose and remember to elevate the end when you disconnect so contents of the hose drains...


Inquiring minds want to know...

Is this a problem just at the place where you are now, or is it a constant problem? A photo would help illustrate the problem, since I can't see how the sewer drain would be lower than the dump drain.

Happened to me once, last Sept. You have two choices:

1. get a macerator pump

2. let the hose fill up then walk it from the RV to the dump station, over and over and over. That eventually empties the tank. It is what I did.

I have a pretty low black drain on my trailer. I have had a number of cases where the campground provided clean out at the site was above the ground. If you run the hose directly to this outlet the last 5 or so feet are below the outlet.

I followed a suggestion I read here about getting a 10 foot plastic rain gutter and cut it into a 4 and 6 foot section. I use these to make a ramp. I have yet to ever camp at a spot where the outlet is actually above my black tank drain. If this happened a lot I might look into a macerator but would rather not spend the money just so I can carry another piece of equipment I would seldom use. Been doing this since the 80's without any impossible issues.

I had this situation at a state Park in Oregon this summer. The sewer drain was 12" above the ground.
When I drained the tanks most of the effluent ran into the sewer inlet, but the drain hose on the ground still was full. I made sure the hose was well connected on both ends and lifted the hose from the trailer end up and drained it into the sewer pipe. I had to do it several times to completly drain the tank.
When I was done I unhooked from the trailer and carefully washed it out.
Only a few of the sites had this elevated drain??

This is a problem that all owners of coaches like mine face. (once 12K+ now only about 9K after 40+ years) Many have installed macerator pumps and dealt with the reliability that is way lower than gravity. I thought about carrying a portable macerator of some kind, but without any external storage, I would not know where to keep it. Most of the better campgrounds have the dump at grade, so they are no problem. If we are at a campground (we rarely are) and they have the pipe sticks up, I look for another slip to go to.

In short, I don't have any good answer for you.
