Bypassing Blackwater Tank

Hi

I recently acquired a 1971 31' AS and would like to direct the blackwater and grey water material directly out instead of going into the holding tank first. Is there a way to do this?
I see some valves but don't quite know what position they should be in.
I don't have a service manual yet.
Any instruction would help.

Thanks

The toilet usually empties right into the black water tank.
You could hook up to the sewer and leave the valves open.
But the common method is to let the black tank fill up
and it's mass, weight , and liquid will help the evacuation. Then use the toilet to flush the black tank and the grey water to flush the hoses.
If you rig is new to you, maybe you could experiment with water.

You can take the drain cap off the sewer outlet, hook up a sewer hose to a sewer, which will take care of the gray water.

under no circumstances, attempt to open the dump valve and leave it continuously open.

If you do, solids will not be washed away, therefore they will accumulate. When that happens, your in deeeeeeeep trouble.
