So a 3 way T shaped fitting with a plug in one end? Seems do able. I do have very limited space - evolv itx case so going to be a squeeze.
Thanks for them tips. I never thought of doing it that way.
How would I drain from it? Turn that he hang off and turn upside down to let that hehe liquid move out of the way and that he hehe hen unplug it and turn it back?
Thinking the tap might be the safer option.
Is it OK to have a T junction with a tube leading only to the tap? Or would that cause some sort of awful flow disruption?
Its sort of depending on your loop.
Just having a plug can work if a few drops of fluid below it is acceptable once you need to drain it (you just put some paper below).
Because due to physics and stuff, if you only unscrew that plug in the loop, and assuming it is not leaking in air anywhere else, the fluid will not come gushing out as there is no way for air to get inside. And you can simply attach a piece of hose there and after that unscrew ex. the fill port in the reservoir to let air in (and fluid out through the drain)
But yes, a drain valve or a piece of hose with a plug at the end that you can aim outside the case before unscrewing the plug is obviously the superior choice.
As for having t-junctions and a dead end, its no problem, fluid will flow wherever there is least resistance, and in this case its around the loop.
If you have a dead end, you might want to, when you fill your loop, open it once to fill it with fluid.
