Transfer pump question.

The park we stay at during the summer has 115v hook-up, but no holding tank drain or potable hook-up at the site. Have any of you found a pump to empty our black/grey water tanks into the Totes in the back of my pick-up? I'm getting a little old to lift those Totes after draining. As as retired irrigation contractor, I'd be leery (my pun) of using any of the units where the potable is hooked-in: there is no way to test that the "anti-syphon" valves are working and "backsyphonage" (a fire or heavy pull on the water supply) would be a huge concern. I'd think most parks would frown on those units. Thanks, M

Get a 12V Jabsco Macerator pump. Works great, and they make fittings that adapt to regular drain fittings.

I appreciate your feeling about backflow prevention. Thanks.

Thanks Mark, I'll take a look. Since we don't use TP in the black water tank anymore, simply use a sack and garbage it (don't ask why we quit using TP in the tank, the fix was not a pretty situation), I'm wondering if a macerator pump is needed?
Yes, the backflow/backsyphonage problem is huge in campgrounds, drives me nuts!

If you get a Flojet pump kit from PPL, I think it will be just as cheap as building a system without the "macerator" capability. Comes in a nice storage box and hooks up to the regular 3" drain pipe.

I'd been hoping to use 3/4" hose to do the transfer, but these pumps look like it'd be a bush-down nightmare.

For your application, the types that use potable water for the pumping action would be of little value anyway. The potable water used flows out the pipe with the waste and you would fill up your tote long before you emptied the tank.
