Most couplers say they don’t work with flow control faucets. Chi Company has a specific Perlick flow control coupler.
Just adding some finishing touches to my keezer, noticed someone was looking for an idea to store picnic taps. Thought I’d share what I did. I used cup hooks and straightened the hook slightly, then drilled a hole in the tap handle to hang it.
Thank-you! Had the suction-cup type in my hand earlier today.
I’m headed to the garage… 
I try to store the downward so anything left in the tap drips out. They can grow so funk up under the cap over time.
- 1 - while hanging them from the handle works for you, I’m clumsy at times and would likely knock open the valve when moving stuff around.
Shake it a couple times! 
IF you shake more than twice you’re having too much fun.
But seriously, whatever it is that grows in there is nasty. It’s exactly as Stevie describes up above. I change my picnic taps regularly to try to avoid this.
Also, although others have said there’s no issue with staling or carbonation loss I find that the beer in my lines goes flat. I typically pour the first few ounces, drink that (or toss it), and then fill the glass. I don’t pour pints all that often and have five kegs on tap right now, so it could simply be a time-based problem.
I haven’t notice any funk in the tap. I do a thorough disassembly and cleaning between kegs and drain the tap between pours.
The taps unscrew and I have found that the taps can get loose causing leaks.
I have a setup that I pump PBW through the lines filling the keg and let I recirculate for a while. I put a silicone line on the open party tap so it gets a cleaning at the same time as the keg, no funk.
