Waste Macerating System

We have parked our motor home on a lot which has a sewer discharge located approximately 300' away. I was considering installing a macerating system to pump our waste to it but not sure if the distance is to far. What do those of you with experience say about this idea? Can a macerator push waste this distance. The distance is a gentle downward slop.

    I doubt you'll be able to push it 300'. It won't get it done with a hose smaller than 1". I've done 150' and that was pushing it using 5/8 hose.

    You don't want 300' of poop in a hose that won't pump...just sayin.....Dennis

    I have a Flojet also....use it to pump 75' with a 2' rise using 3/4" hose. Motor gets pretty warm so I take a break between pumping tanks.

    I don't think Flojet will pump 300'

    Per Flojet Tech Sheet:
    Hose Size---------Maximum Hose Length
    5/8” (16 mm)---------25 feet (7.5m) max
    3/4” (19 mm)---------50 feet (15m) max
    Recommended lengths are based on horizontal discharge. Longer discharge runs create higher resistance and may result in the pump motor over heating

    That garbage disposal set up posted by 'rv2go' most likely would pump 300'

    I use the Flowjet. 75' uphill about 7 feet. I use a 3/4" hose. If I needed to go 300', I would want 1" PVC pipe, if possible. But, you would then have a 300' hard PVC pipe running down the path. They make 1" garden hoses. But, that would cost a fortune.

    I think it would work though!

    Good luck.

    I use a Flojet Macerator Pump Model 18555 with a 3/4" hose. It will do the job with ease. It uses 12 volts from your battery. Here is the best price I know of: http://www.adventurerv.net/flojet-portable-macerator-waste-pump-p-629.html

    Take a look at Sewer Solution! It's a lot cheaper and it uses water pressure to push waste to the sewer. You can also use PVC for your piping.
    Good Luck

    I'm guessing that it would work, perhaps slower than normally.

    Use as large a diameter hose as possible, and it should not be a problem. I have a 3/4 inch hose for mine. They make a 1 inch hose, but it may take some looking.
