Long distance dumping

[HarryStone]

I'm setting up an RV pad on the side of my house, am working on putting in a power drop, but the big problem is this; My Sewer access is on the side of the house, about 75 or 80 feet from the black/grey tank port, the good thing is that it's flat. I've looked into macerators, and it seems the only one that can push that far is the Clean Dump. And it requires 1" hose, but only comes with 10 feet. What can I use to extend it the extra 70 feet I need to get to the sewer drain? The only dump station in our town, according to the campendium app costs about 35 to dump, and I'd like to use the RV as a temp guest room. Thanks for your help in advance.

My Flowjet does 75' in a 3/4" hose with no problem when it's flat.

The dump station charges $35 to dump????

4" ABS drain pipe is about $10 for a 10' stick with bell ends.
Nice thing is the joints are deep and do not require glue for temporary on the ground installation.
70' would require about 7" of drop following the 1" of drop per 10' rule.
Food for thought

PVC pipe? Macerater to pipe with the 10 ft hose. Bury pipe if terrain permits. I had setup similar to yours several years ago, this worked well for me.

Here's a kit you can use to make a macerator from a garbage disposal. I'm using a 1/2 horsepower disposal thru a 3/4" 50' garden hose with no problems. Drained and pumped 30 gallons of black and 40 gallons of gray somewhat slower than a gravity dump but still seem quick enough. Disposal ran smooth the entire time with no surging or slow downs.

The kit seller claims that using 3/4" hose that a 1/2 HP disposal can push the liquid 100 foot and overcome 7 foot lift. I wonder what a 2 HP disposal would do (insert a Tim "The Tool Man' Taylor grunt here).

Like others said, bury a 4 inch pipe, and have the inlet beside your pad. It will cost a bit, but will be so handy.

Maybe even start a small cash for dumping business with your buddies that have RV's. 10 bucks a dump, and it will pay for itself.

My flojet will pump no issues to 90ft uphill with a 3/4 Inch hose

I have a DIY macerator setup made using a pump like used in a boat and some pieces from Home Depot and my shop.

I pump to a sewer cleanout through 150' of garden hose.

Did you look at the SaniCon products, they dump that far.

For temporary use, try a fold flat 1 inch or 1.5 inch roll up hose. Very light weight and compact. Get them at farm store or pool store. They are also very cheap.

why not just install a small septic tank next to the RV pad. 50 gallons once in a great while won't require much.

[HarryStone]

Thanks for the replies. Digging and putting a pipe in the ground is out of the question, as is a septic system. I'm in a dense residential area and septic isn't allowed. A pipe or hose above the ground for a couple days/week at a time is what I'm looking for. We Be Gone; I did consider the flat hose. Will that hook up to the macerator? Thanks.
Unicorn Driver; What model Flojet do you have? I looked at the 18555-000A, but the manual says no more than 50 feet?

That's the one I got Harry. I am piping 5 foot up hill also.
