Wolf Pup - Sewage

The sanitation hose comes standard with most travel trailers.

These things are bulky, need a precision angle to flow properly and are a bear to clean.

There's a better way. A macerator - which empties your tank(s) via a garden hose.
There are commercial varieties at the camping centers.
I'm a shade tree mechanic so I use a cheap model and modify it myself. I like to have a clear section so I know when the flow is clean or stops.

These need heavy amps of 12vdc, so a separate circuit is generally in order, although a battery jumper box may be used otherwise.

To empty the tank.
*remove the cap

*screw on the macerator

*attach a 3/4" garden hose to the macerator

I'm using 1/2" garden hose and haven't had a problem yet.

 *put the 'output' end of the hose in the sewage port
   this port may be at the campground, or a truck stop dump station, even a rest area toilet
*hook the macerator up to 12vdc
   it's nice to have a switch for this circuit, but if you're using a jumper box it's not necessary

*let the current and sewage flow
*unattach the hose and screw the ends together

*remove the macerator
*cap off both ends of the mascerator

*put the cap back on sewer outlet
*throw everything in the storage compartment and head down the road.

At the campground, I run the macerator only when the tank is nearing full, but if I'm at a campground for only a day or two I don't even hookup the macerator - I empty the tank into my septic system when I get home .

For convenience to a high amp 12vd circuit, I tapped into the TT power panel with 10g wire and made a port to get hold of the wire from inside the trailer.

 

 I also incorporated a lit switch in the circuit so if the macerator trips out (if run too long or it gets jambed) I know I still have power to the unit.

To me, this is the simplest and easiest way to deal with emptying the gray and black tanks.
