Drill pump/ grey water transfer

[Chris Retired]

Has anyone ever hooked up dump fitting cap with the hose outlet, hooked to hose-drill pump-discharge hose-then to black water flush fitting to move water from grey to black?

If so, chance of plugging up the flush fittings with any debris from the grey tank?

Myself I would not do this having to deal with a full gray tank is much less problems then a full black tank. My concern would be for plugging the nozzle of the black tank sprayer and also any scum left behind from the gray water. Gray water to a bucket to the toilet seems like a better method to me. JMO

You are likely to. Clog the inlet screen on the pump or the flush line before the spray head. Why not pump it to a tank and take it to the dump?
Or is it that you need more gray capacity than black?
We wash dishes outside when out for a while. The screen in the dry sink keeps food contained so we can toss it in the trash. Not so sure I would do it in bear country though. I'm sure there is still food scent to attract them.

I would not do this as it is very easy to clog up the sprayer in the black tank flush and it would be difficult to clean with out a major effort.

DONT DO IT !!!!! I see plugged flush fittings...
We have had a few occasions requiring to move grey to black.
Leaving the cap on the discharge,
open the grey dump
open the black dump, grey will flow to equalize between tanks.
Close the black 1st then the grey.
use a basin under the discharge and slowly open with caution...

We use a basin for washing dishes and that water goes into the toilet to begin with.

If you want to pump the gray water somewhere, why not just into a tote and take it to a dump station.

I use a Flowjet macerator pump to empty whichever tank is filling up when I'm boondocking. It goes into a 28 gallon Rhino tank sitting in my pickup bed. Dumps easily through a regular dump hose from the side valve. No lifting on either end of the process.

We do dishes most of the time inside. So we wipe them down good with a paper towel before washing them which saves a lot of water and gray tank space. It also keeps the gunk out of the gray tank as there is not a flush for that tank. Your gray tank can also get pretty nasty with grease and stuff left in it for a while.

Yep, pump costs a few bucks but super handy setup to use at home or on the road.

The pump to a tote to dump station, or if we go home with full tanks, the pump to a 50' 3/4" black tank garden hose in through the bathroom window and down the hopper.

Also how we know using Happy Campers tank treat eliminates black and gray tank odors...
