Maximum length of sewer hose?

Similar to what others have mentioned, I used about 30' thin wall PVC to get from my driveway to cleanout. I glued a 90* elbow and short pipe on one end to set into cleanout. On the other, I used a short piece of regular RV sewer hose and clamps so I can easily attach my 10' hose. After dumping, I rinse fresh water down the PVC pipe, tilt up to drain and store under back porch which is next to the cleanout.

Works like a charm and makes tank maintenance a breeze or dumping after weekend of tailgating with no dump station.

Over the holidays we went Redneck style with 30' of 4" black hard sewer hose running across my brothers lawn to his cleanout. We used our 20' flex to connect for a total of 50' of sewer line above ground. Worked great for the 3 weeks we stayed. As long as you have the elevation drop and neighbors who won't call the city.

Boy, the stuff you people come up with. I have been using my sewer solution for almost 10 years now with no problem. It goes 35 feet and UP 30 inches with NO problem to a bathroom cleanout on the side of my house. It uses a lot of water especially when I give the black tank a good flush. NO, I can't use a macerater. My MH's sewer terminal end is in a compartment with a 6 inch hatch, NO room.
Using my house's new sewer line cleanout will work fine by backing into my MH into my driveway . Stopping with the MH even with the cleanout would be just like using a dump station everywhere. I asked the question of how long a sewer hose can be is because I wanted the option of dumping from the usual spot atop the driveway. I normally pull forward into the driveway very close to a hedge on the leftside, thus allowing access to the MH's right rear door.
I will buy a 20 foot and 10 foot sewer hose and connected them. I have an extra elbow and will attach that to the end. I'm sure now looking at it, it will work fine.

A few years back I was at a Van Nationals which was being held at a fairgrounds. Had the daughter and grandkids with us so every few days the tank needed dumped. The sewage dumper missed us on his rounds and we needed to dump the tank bad. Well, I went around to the other folks that had RVs and borrowed four twenty foot lengths to add to my thirty feet of hose. Looked like something out of the movie RV when I had it put together (without the leaks) and I had to 'walk' the dump to the sewer cleanout all those feet away and not even downhill, but it worked. Shortly there after I got a maserator pump in case I ever had to do it again.

The plumber is installing the replacement sewer line tomorrow with a clean out near the bottom of my driveway about 8 feet away. It will be 35 feet from where I park the MH normally at the top. I can back the MH into the driveway and be 10 feet away from the sewer clean out for dumping only.

I had the plumber install a PVC line near my motorhome spot with a screw on fitting for my sewer hose. Priceless! After reading that you were near the end of the driveway, I had a picture of Randy Quaid holding the sewer hose at Chevy Chases house in Christmas Vacation, I think?

35 feet is .. Well, that is 2 of my 4 houses (I have 2 10's a 15 and a 20).

You said that you have sufficient slope to the cutout and want to know the max length of hose you can use. The answer is that, in theory, there is no maximum length with enough slope. 10 ft., 1000 ft. makes no difference it will drain if you are patient enough.

I'm waiting for someone here to do a write up on the max. feet of sewer hose one could use! LOL

I would not want to be one of the testers!

Here's your answer, answer

Well he probably won't read this, my error. He solved it without reading the instructions.

Why not let the plumber run a line to where you park the RV.
I use my Macerator pump for difficult situations but you need something permanent.
