Try it; a good buddy of mine used a similar system to draw clean water from his urine. I will get the exact method he used and share it here. And no matter how cool some TV hosts look drinking their own urine; just avoid it. if you are dehydrated especially, the effects can be similar to drinking sea water, but that’s for another article. in the Ranger Handbook, they actually recommend you run a drinking straw from the surface down to the water catch basin; in this way you can drink collecting water without disturbing the entire set up.
