uneedav8 Posted February 16, 2007 Posted February 16, 2007 How long do you guys usually run the pumps to make sure there are no leaks and its good to go? I have read overnight in some articles. After the fill, some suggest jump starting the PSU to power the pumps while leak testing. Is that jump start method with connecting the two pins on the ATX ok on the PSU? I have heard some in here say that you can destroy the PSU if you leave it on without devices connected. Thanks for any help. Share this post Link to post Share on other sites More sharing options...
red930 Posted February 16, 2007 Posted February 16, 2007 I very much doubt that jumpering a PSU (for any length of time) is going to be hard on a power supply. I usually wait about...oh...an hour or two, mostly because thats about how long it takes to fill it (for me). But then I'm an impatient bastard as well.

CPDMF Posted February 16, 2007 Posted February 16, 2007 I'm with danvan on the however long it takes to get the system bled leak test but you might want to give it a little longer if it's your first time just to be sure. 4 or 5 hours will be long enough to determine if there are any leaks in the system. From that point I just mark my fill line where the water level is with the computer off and check it daily.. Share this post Link to post Share on other sites More sharing options...
HITandRUN Posted February 16, 2007 Posted February 16, 2007 I agree with the guys! I use an old 300W PSU to fill and bleed the system because most of the modern PSU won’t turn on when you jump them without load. So you need to connect some drives etc. to do the trick. Like I said use an old PSU and you will be fine. Share this post Link to post Share on other sites More sharing options...
UncleDavid218 Posted February 16, 2007 Posted February 16, 2007 lol I know it sounds horrible but I leak test with everything installed. As long as I know that the blocks aren't known to leak, I trust my clamps. But I don't just power up the system and go, I make sure the loop is filled and run it without the system on overnight usually.

radodrill Posted February 16, 2007 Posted February 16, 2007 I personally use my main PSU to power the pump for leak testing. I don't leak test for any given amount of time; I just use the system as soon as all the bubbles are out of the line (often w/in about 2-3 hrs). I've never had any leaks in my rig; but I do secure the clamps quite tightly. Share this post Link to post Share on other sites More sharing options...

walternowi Posted February 17, 2007 Posted February 17, 2007 I am very conservative and my leak test ran > 48 hours. By that time, the system is properly bled (bleeding with a T-line is a PITA) and good to go. Share this post Link to post Share on other sites More sharing options...
RubberDuck Posted February 17, 2007 Posted February 17, 2007 Overnight for me. Just use a old 300w psu & jump start it.:cool: Share this post Link to post Share on other sites More sharing options...
Voltes-5 Posted February 17, 2007 Posted February 17, 2007 I'm with the first 4 responders, he he he. I'm impatient too. I use a psu that came with one of my cases to power the pump with an Asus board. As soon as the air bubbles are gone, well it usually takes me about couple of hours to do, then I run the system right away. But, it never hurts to be cautious about this things. Do a thorough leak test for at least overnight with the line, then when you are comfortable with your clamps and what not then run it.

PhoetuS Posted February 17, 2007 Posted February 17, 2007 The longest I have leak tested is 8 hours. The only reason I let it go that long is it was my first time. Now I let it test for a few hours, really just long enough to bleed the air out of the system. I too am impatient about it. Though, I am very meticulous about all the connections & am generally confident that there won't be a problem. I also test it in the case with all the components, but I don't power anything up except the fans & pump. Share this post Link to post Share on other sites More sharing options...
