There are several
options
when handling grey and black water.
The old stand by is
the “blue boy”.
All I can say about
it is that it will work, but that it is messy, has limited capacity,
and
has to be drug behind the truck to the dump station. Everyone seems to
have one and they are not cheap. So here is a better way to go if
you want to think outside the "Blue Boy".
We purchased a
macerator
pump and have a 50 gal. tank rigged up to dump.
The 50 gal tank was
about $120.
It stores in the center
in front of the hitch length wise. See if this would fit for you in
front
of your hitch. W 19 H 20 L 38. This even fits with both our black
storage
boxes on each side of it. The pdf link for the tank we got... http://www.norwesco.com/PDF/LST2004.PDF

PCO tank part 40664
Updated links => We got our Tank and parts from www.sprayers.com
And you will need a 2 inch through the tank fitting NORWESCO TANK FITTINGS ( part number Norfitt 200) at http://www.sprayers.com/SprayerCat_2007/191-192.pdf We called them and they will UPS. And then a 2 to 3 inch reducer from your RV dealer that goes to the gate valve. Which is the RV slider shut off valve.
We bought our pump from ABS Alaskan as a stand alone unit.
Also see RV SANI-CON for prices etc. They have units with attachments so you don't have to build them from scratch.
We added a clear
curved
3 in. RV connector on the end of the hose, a short section of HEAVY
duty
3 in hose. The pump has good suction and a weak 3 inch hose may
collapse.
A short clear short
1 inch section on the outlet.
We want to see stuff
going in and out to make sure the pump is working.
A quick connect,
release
connector to the longer 1 inch heavy duty hose. Which we got at a farm
and market store. Was intended for a farm sprayer.
We have found we can
go two weeks before having to dump gray and black. It takes about two
trips
with the 50 gal tank. There are two of us, your volume may differ. We
have
been accused of being full of it though!
The 12 volt pump chops up the waste from
the 3 inch hose and pumps it into the smaller hose.
It pumps uphill to the tank in the
back of the pick up just fine. Feed the 1 inch hose into the tank.
(below)
We have a quick disconnect on the 1 inch hose.
We store the pump and short attached 3 in
hose in a cheap plastic tool box. No mess no fuss.
You do need a 1 inch hose, a smaller one
will not handle the pressure or volume. Do not use a 3/4 inch
garden
hose.
We first found a 1 inch flat fold up type
one (like a smal cheap fire hose) and when hooked up it blew with many
pinhole leakes. So we went with the strong sprayer hose.
On the left bottom
(above) is the 3 inch drain hose connection as in the pic below.
Has a drain pull handle
just like on the 5ers drain system.
The 50 gal. tank
goes
between our two black storage tubs when traveling.
And you will need a 2 inch through the
tank fitting NORWESCO TANK FITTINGS ( part number Norfitt 200)

We called them and they will UPS. And then a 2 to 3 inch reducer
from your RV dealer that goes to the gate valve. Which is the RV slider
shut off valve.
Hook up a 3 inch hose to the tank at the
dump
site (pull the value handle).
Remember to close the value handle
as you do not want to remove the drain cap with the value open and no
hose!
When this tank drains it drains with a huge wosh! And the best part is watching the faces of the blue boy users at the dump site as they watch us dump.
