Have any of you emptied your tanks successfully using 100' of 3" sewer hose? I need to empty tanks a couple of times and am thinking of using regular sewer hose. it's about 100' and flat all the way to the drain. What are my chances of no mess?

Just like building a septic system - you need a certain amount of slope to the pipe or hose. Too steep and the water runs too fast leaving the solids behind. Not enough slope and nothing flows.Bill

If it's a long term situation you might consider a maceration pump. They make pumps that mate directly to an RV sewer drain, and then I think they pump through a garden hose to the final destination.

Thought about a pump but that's $200+ and only $60 for sewer hose. It will only be used a couple of times.

I use up to 60' (2 x 30' hose) and follow the gravity flow rules with no issues. While draining, you might have to coax the flow by lifting the hose in a few places. It's hard to have too much hose in case of cuts, age and distance to some dumps.
