Bleeding a horizontal res

[mike gunnz]

Ive lifted this shot of someone's ongoing build from another forum (yes I've posted the question in the thread - no reply yet), as I'm intrigued to know how he intends to bleed a res that has been mounted horizontally. As you can see its the 800D case and the tube protruding out back is the intended fill port.

Has anyone else mounted a cylindrical res horizontally like this before and successfully bled the loop. It looks to me as if he's gonna have a hard time stopping air from being continually pushed back through or am I missing something?

I hope I'm wrong, as I rather like the idea, if it works I may try it myself in a future build.

surely providing the inlet and outlet are under the level of the fluid so that air cannot get back into the system, it shouldnt matter what orientation the reservoir is.

If its a low flow pump then it shudnt be too much of an issue

My guess is that when he fills it he will stand the case on its front so that both rad and rez are vertical. This will allow him to get all the air out of the rad. He will continue to fill until virtually all the air in the loop has gone such that when he puts a stopper on the end of the tube there won't be any air in the rez, or a very small amount at the most. The rez is then acting like any other bit of tube, which supposedly will lead to lower pressure drop through the res. If any air then finds itself in the res after a while then all he has to do is rotate the case to get the air bubble to go into the fill tube and hey presto, completely air free rez and loop again. I'm not sure why he has such a long fill tube though, I suspect he isn't going to do what I've described, or is going to cut it afterwards.

If he trys to fill it with it stood as shown in the pic he will struggle to get all the air out of the rad imo.

*OR* if that rad has a bleed screw, he could virtually fill the entire loop with it stood as in the pic, without turning on the pump once, but even then I would still reccomend doing standing it on its front for a final air purge as even with a bleed screw there will always be some air either trapped in the rad, or which will accumulate in the rad when the loop is running as that is the highest point.

as long as he has enough fluid to cover the outlet to the pump it'll be fine,

he's essentially got 50% less use from the reservoir as the bottom half in that configuration is useless
