Hello, I'm about to order my new pc and I'll be doing my first loop, and I just have two questions that hopefully someone can answer.

Just a quick note, all parts in the loop will be thermaltake, except for the rads (getting thinner ek rads).

I want to have a drain point at the bottom of the loop, but the lowest point in the loop is the pump itself, i was thinking of doing it like this:
Pump > F-F Extender > 4 Way Valve > Drain. With a plug on the bottom hole of the valve and an RGB fitting in the top hole of the valve going into the tubing.

So.... Would this configuration cause some sort of backward pressure or slow the flow of the loop in any way?



And secondly, I obviously need a fill point.. I'm using a pump/res combo, and my pump and res will be at the lowest point of the loop....

So, will having the fill point at the top of the res be a problem since the res is at the bottom of the loop?
By problem I mean will the res just overflow out of the fill point when I turn the pump off as I'm filling the loop?



Both are probably incredibly stupid questions, but any explanation on how this would work and/or effect the loop would be insanely appreciated.

Thanks in advanced.
 
Solution



couple of inches of tubing from the outlet then the t-piece

part of t-piece with the ball valve is aimed downwards

so the part of it with the main flow so to speak is straight across
for my drain point

i used a t-piece screwed a ball valve on there

then a plug/blank on other end of ball valve--just in case--though takes a bit of force to turn the ball valve any way so unlikely to get accidentally opened

any way

to drain i take the plug/blank off--screw on a length of tubing then open the ball valve

there will be a bit of back flow into the res as you fill the loop--but it wont all run back

thats why i have top rads with more than 2 ports--much easier to fill from the top rad as gravity is on your side

Is the t-piece connected directly to the Pump outlet? My only concern is that naturally the fluid would want to flow straight, not up. which would bring it straight to the drain maybe causing some backward pressure?
