Custom loop drains minimal flow.
Custom loop drains minimal flow.
Hello everyone, I've been working on my first custom loop and everything is running smoothly. Recently, I planned to empty it for maintenance or upgrades, but when I checked the drain valve and fill port, very little coolant was coming out. The reservoir still had half its capacity with no flow detected. Some online research suggested my loop might be misconfigured, but I'm not sure. Could someone review the design and give advice on how to fully empty it? I'm considering quick disconnects first, but I need to safely drain it before that. Thanks for your help!
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.
