Really bad Rowe changer problem

Today, I tried to put the t-handle back in the changer.  Which you could do but when you turned it the t-handle would not catch.  The t-handle was round inside with no hex nut to turn the vault arms.  But I am not sure what it should look like.  I just know it is broken.  But anyone could come to that conclusion.

RO Reject water project

I installed pvc and 1" hose today.  For my RO reject water reclaim project thing.

A pump will be used because the ro reject tank could not gravity feed the holding tank.  The float switches on when the holding tank is low then it provides power to the solenoid and the pump.  This is through the "Magic" box.  The magic part I do not know how to implement yet.
