Water and Boondocking 101 Dumping Gary and Black water


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

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.

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.
