Flojet Question

[wbwood]

Considering the Flojet system for dumping at home into our septic clean out. Our clean out is behind our home and no way to get RV close to it. I saw a thing from the manufacturer that with a 3/4" hose the maximum length is 50' on a horizontal surface and nay further could burn up the motor. My yard slopes from the road to beyond the back of my house towards the clean out. I assume that if I used it at the top of my driveway (at the road), that it wouldn't make much difference of the length of hose due to gravity and it going down hill. It would be about 100' (twice the length for horizontal).

Anyone think otherwise?

I bought two 50' lengths of 1" gatorhyde hose (doesn't kink) and have no problem emptying. If you use 3/4" hose I would watch the heat of the motor (monitor it with your hand) and stop to cool it if it starts getting too warm.

Thanks...ours will be downhill with about a 15-20 drop in elevation over about 100'.

Awesome....

Years ago I wrapped white vinyl tape around the handle of my fresh water Aquatainers ...



... and red vinyl tape around the handle of the grey / black water Aquatainers ...



Obvious, and no one has ever confused the two. :R

That is a cool idea for using Aquatainers, but I worry that someone would get them confused with potable water, chug one, and expire messily. Maybe if someone could make some rotocast containers designed for non-potable water with obvious, "do not drink" markings, as well as a proper color container, so someone doesn't confuse it with gas cans or diesel cans either.

7: This isn't the OP's use, but if using a "blue boy" waste tank with a pickup truck, place it in the truck bed while it is empty, use the macerator pump to fill it up, drive to the dump station, hook up a slinky, and let gravity do the work. This is a lot easier than trying to heave a full tank into the truck bed.

Easier still - don't use a "blue boy" at all. Instead, I use 7 gal Aquatainers labeled for grey / macerated black water use, each of weighs 60 lbs when full so lowering them from the truck tailgate to the ground for emptying directly into the dump station sewer inlet is easy and avoids the need for a stinky slinky entirely, along with the need to flush out a slinky. K.I.S.S. :B

I love the clever use of connectors. I wound up using jumper cables and a "poop battery" whose sole job was to provide the 20 amps for the pump, and was kept trickle charged.

I would highly recommend the FloJet. A few items I found:

1: Get a stool or portable chair to sit on. kneeling to attach and man the pump is not fun for the back.

2: Get a transparent sleeve between the sewage port and the macerator pump. You want to shut off the macerator pump just as it empties, because it will burn out and destroy itself if run dry for more than a few seconds.

3: With the pump in place, you can empty the black tank, then open both valves, allow the gray tank to backflush the black, then empty that... saves a lot of water, and does the same job for clog prevention.

4: I personally use a black rubber hose with words on it plainly marked, "NOT FOR POTABLE WATER". The hose I use to flush out the macerator pump is green, and has vacuum breaker check valves on both ends. My white fresh water hoses are stashed in a separate compartment.

5: I used an extra-wide hose, especially when going distances of 50 to 100 feet.

6: The pump gets stored in its own plastic tub with a tight-fitting lid, and it, as well as the hoses get capped after use.

7: This isn't the OP's use, but if using a "blue boy" waste tank with a pickup truck, place it in the truck bed while it is empty, use the macerator pump to fill it up, drive to the dump station, hook up a slinky, and let gravity do the work.

Have been using the Flojet "Poop Cannon" for 3 seasons (this being the 4th)... never a problem.

Ours is set up with 10ga wire from battery to a trolling motor plug installed at tank outlet.

I've chosen to convert all my exterior 12 volt connections using Bargman connectors, including a Bargman next to the trailer's sewer outlet for powering my FloJet macerator. It's located ~ 15' aft of the battery so 12 gauge cable is quite sufficient.

Have been using the Flojet "Poop Cannon" for 3 seasons (this being the 4th)... never a problem. Haven't had a 3" sewer hose on board in as many years. (2) 25' black rubber hoses that are used for grey water with a grey water cap...when needed Flojet hooked up to same hoses and empty 32 gal of black in 3 minutes or so... dump at home all the time into a 2" sanitary sewer line ran specifically for this.

We have been using ours for 2 years now to empty our tanks at home as well.
Ours is a 30' run and about a 3' uphill grade.
Other than it getting pretty warm we haven't had any issues. We have a dedicated black hose for it. We have two drains on our RV so we ran connections at both dump valves. We did you 10 garage wire as it is just about a 40' run from battery down to last dump valve.
Thought never hit us to try a 1" hose but we just bought a new house and are planning on putting in a pvc line just for the RV to make it easier.

Tried the dumping you're describing a couple years ago at a campground. Used 1 inch swimming pool hose with PVC couplings to go from the Flojet to the dump station (about 100' and slightly up hill, maybe a foot of rise. Didn't work so well as the swimming pool hose would easily kink and stop the flow. I believe it would work on your application. The drop you describe you may even be able to dump using just the swimming pool hose without the FloJet. The 100 + feet I bought rolls up into a plastic storage bin just a bit larger than a shoe box.

FloJet is a Macerator and doesn't use any extra water as it is motor driven.

Think you might be confusing it with the 'Sewer Solution' which uses high pressure water as prime mover.


I have a Portable FloJet Macerator that I use at my sisters house.

From RV to septic clean out is 75' with a 2' rise.
I pump 50 gallons of black then let motor cool down for 15 minutes then pump 50 gallons of grey....cool for 15 mins and finish up with last 28 gallons of galley tank and rinse water

Had my FloJet for 8 yrs now
