Pressure testing question

post #1 of 22
Thread Starter 
Hi all, first post.

I got the Dr. Drop testing kit for my first build.

The instructions say test the loop for an hour and there should be no loss of pressure.

There didn't seem to be any drop, however I left it overnight @ 0.5 bar and lost 0.02 bar.

Should I be concerned about this?

that is probably always going to happen overnight, i usually go for an hour or maybe 2 if I've got something else to do. Are you sure you were testing at 5bar though? That is 72PSI and I feel like my rads are going to pop at 10psi... I know alphacool claim something crazy like 8 bar but the other components could possibly be damaged from such pressure
edit: the max that that gauge goes up to is .6 bar so you didn't damage anything.

Haha, oops. It was at 0.5 bar and I lost 0.02 bar.

But yeah, that's cool. I realized I never checked the drain plug on the reservoir and it wasn't that tight so that may be to blame anyway.

.02bar is definitely ok to lose overnight. .5 to .48bar, Thats fantastic really, especially if you had a plug that wasn't quite snug thumb.gif

fill that loop up! smil3dbd4e4c2e742.gif

I am too excited, been wanting to do this for years.
Sort of procrastinating atm because I forgot to put the I/O cover on the motherboard so I gotta pull that all off.
Right now I'm just trying to decide if I should run pre-treatment or just put coolant in.

Cool looking rig man! I was going to ask if you would post a pic, but decided not to be too demanding rolleyes.gif

did you flush the rad with lots of warm water already? What brand of pre-treatment is it?

This ! The gunk from the manufacturing process of the radiator can damage your pump redface.gif

I didn't flush the rad mad.gif, another noob mistake. I read that EK rads come very clean... but if I must pull it off I will (?)
I just have the sysprep pre-treatment that the Primochill tubing comes with.

Your loop is pretty easy to take apart, remove the radiator and clean it with destiled water + vinegar thumb.gif

Yeah... I really should. Especially if it makes running pre-treatment less important.
