How to Drain TKS??

[Rotorhead]

Pretty easy question with a hopefully easy solution too. I have 2 gal of TKS onboard that's just sitting there and would rather have better W&B margins living in ABQ. Is there any way to drain/ offload some without opening panels? If the bottom panel does need to come off then so be it, but thought I would ask the guru's first.

Thanks in advance.

Make sure you are cycling the system every month.  That 2 gallons is probably enough for 2-3 months then you are just going to be back to adding more.

I would advise against letting the TKS system sit unused for an extended period of time.  A few thing we've seen from inactive systems:

1) Corroded filter bowl $1,300

2) Seized windshield pumps $900 each 

3) Corroded main metering pumps $2,860 each

4) Panel purging required $ is dependent on labor

We recommend running the system at least once a month.  Ideally twice a month.

Yup, completely understand those factors and prime it on a schedule. Is there a way to offload it in the meantime in preparation of a trip?

You will have to access it through the belly, but inboard of the right wing is a finger strainer.  Disconnect the line going to the strainer and be ready with a bucket.
