flojet macerator questions

I have a wire chart instruction sheet in my hands from a different manufacturer. It is most likely the same chart. Most likely the same pump as it has the same info. Mine says that the #10 for 15' would be for 3% voltage drop. You can use 10% voltage drop and be within specs. Mine has 2 columns. #14 is good for 15' @ 10%. Keep in mind, that is total footage pump to battery and back to pump. So you are talking 30' of wire. Mine will be 50' total and I will be using #12 per my chart at 10% voltage drop. It does work out. I am a master electrician. I have not done the hard math but I do know that #10 is way overkill for a 15' run. This makes for a much easier installation. The pump will dump a 40 gal tank in less in 4 min. I'll be using a 12 ga extension cord and blue crimp connections.I will be pumping 50' thru a standard 3/4 garden hose per the instructions.

I used Powerpole connectors, this company will make up whatever cables you need.

Trying to decide how to set up Flojet macerator pump. I need to make an extension cord and it looks like I will need 10 ga wire for a 15 ft. run. Any suggestions on what type of connections to use? It comes with sae to sae quick disconnect but I can't seem to find a pre-made cord in 10ga. that is 15ft. long.
Does anyone know what size wire is used on the cord that comes with the macerator?
I was also told to make sure to use the backflush as the reduced size of the outlet slows the flow and can leave stuff in the tank. So I was thinking that maybe I could run my stinky 3" hose to where my batteries are and hook flojet at end of hose. I would do away with the need for a dc extension and maybe have better flow out of the tank to the macerator. Any thoughts?

I bought a pair of 12g SAE connectors (12g for 6 inches is not a problem) and made my own 10g cord.

Using the backflush is a good idea. Instead of that, I use my tank rinse to achieve the same result.

Running the stinky as the initial stage won't help unless you have enough length to take the entire contents of the tank. All you will do is have the tank dump a couple of gallons of "stuff" into the stinky, then slow down to the same rate it would be if you had the Flojet directly on the outlet. Only, now, the backflush does no good, whatsoever.

I have a Flojet Macerator. What I found that worked best for me was to use a Harbor Freight Power Pack. Around $100 after a 20% off coupon. Just use the booster cables, a clear 45 degree fitting so you can see the discharge, a 1" diameter garden hose and you're all set. Easy and portable. If you already have a power pack, even better. I always use my black tank flush after getting rid of the "contents" until it runs clear. It takes me about an hour but well worth the time spent to be able to do it from home.
