I am finding I am losing quite a bit of butane in the hose from the tank to the terp and then the hose from the appion to the tank when done a run and disconnecting everything.
With the blue hose from the appion is there a reason it does not push all the butane into the tank when done? I leave it running for about 5 min after I close the recovery valve on the terp.
With the red hose from the tank to the terp, after the last flood and column dump can I turn off the valve on the tank and then reopen valve 4, will this suck out all the butane left in that hose? I was concerned that some material would somehow get pushed into that hose during the final recovery down to-22.
I was having the same problem. My solution is:When I'm almost done with my last recovery, I close the valve to the recovery tank
and turn off the appion. Then pull up on the on the safety valve and vent off some off the pressure (Propane).
Then finish the recovery with 15-20 psi in the tank instead of 50. When I unhook the lines, there is no wasteage.
