Dear Subscribers,

 

My AC condenser in the cabin has a port (straight tube approx 3/8” diameter) for water that condenses around the cold unit.

 

I want to get this water outside my pressured cabin. During the LOBO maintenance workshop last year I took a picture of Jeff’s old plane of how he solved the problem (picture 274).

 

With parts that I found from MCMASTER CARR (best source ever for most of the parts with industrial quality you need to build anything) I created the assembly that you can see on picture 212. I have doubts about my dimensions now. My tube is 7/8” inside diameter. The ball is 0.787” diameter. The ball can make about 3” stroke inside. The fittings are the one used for the static port line (1/4” outside diameter line). When I use a nylon nut on the inside of the tube to secure the fitting I still hear a little air escaping when blowing in. When I use an aluminum nut the ball seals the unit completely.

 

I got concerns now that

- my reservoir 7/8” diameter x 3” lengths is not enough for the amount of water produced by the AC condenser

- the ¼” outside diameter of the nylon is not big enough to let the water run down freely inside the line (it might get stuck like in a drinking straw????)

- that when the unit seals up completely (with the aluminum nut) the water will not get to my reservoir when using the ¼” outside diameter nylon tubing

 

Any ideas would be appreciated

 

Thanks

 

Ralf
