Custom Loop Draining Very Little

[Bloxlord]

Hello All,

 

A little while ago I built my first custom loop and everything has been going great. Recently I wanted to drain the loop to preform some maintenance/upgrades, but when I opened the drain valve and my reservoir's fill port, very little coolant came out and I could see that my reservoir was still half-full with the coolant not flowing anywhere. This and some online searches have led me to think I designed my loop wrong in some way, but I'm not sure how. Could you please take a look at my loop and advise me on how to fully drain it and how to improve it to make draining it easier in the future? (I'm thinking of adding quick-disconnects but first I need to safely drain this thing.)

it's not all bad. you need to open your fill port to let air in too.. and connect a loose hose with a fitting so you can blow air into it to get fluid out.  a hose clamp might be nice to stop flow in one direction so you can blow out the other part of the loop too.. 

 

My setup has 3 radiators.. and is an open case TT AH t600 so i have a drain port at the top of the loop in the back.(my radiator had a port there  ), and at the bottom... and a valve to close one of the directions so it's easier to blow out fluid. you will only get all fluid out if you do a total disassembly. 

i currently have all ports on the side mounted radiators on the top so it keeps fluid after blowing most of it out.
