Need advice on drain port

post #1 of 9
Thread Starter 
What are some of the ways to implement a drain port? I'll be using Alphacool XT45 rads, so there are extra ports all around. I was thinking of using a ball valve on one of the extra ports, or a quick disconnect, but these options are pricey.

My loop design:
Alphacool XT45 280mm (roof)
Alphacool XT45 140mm (rear)
Monsoon Series Two Res/Pump (5.25 bay)
CPU Block

If I set my case on its backside, the rear 140mm rad will become the lowest part of the loop, and could theoretically be easily drained through one of the extra ports on the rad.

Just use a tube and a plug. Easy and cheap. Having a decently long tube can make draining a lot easier as you can just stick that in a bucket and not have to worry about spilling or dripping the liquid. To get all the coolant out you are going to have to tilt the case most of the time anyway so again the tube comes in hand to keep the wrong things form getting wet.

Just make sure you place the drain plug/port/valve at the lowest point possible in your loop.
Trust me, it makes it 10x easier when you don't have to tilt, rock, or hold a case in weird angles to get all the liquid out

If you do it on that backport like you mentioned seems like it will be easy and without a mess

I'll go through my most recent setup. Maybe it'll give you some ideas of your own.

I have a 480 rad up top and a 360 on the floor of my case, both facing in an up/down orientation (as opposed to side-to-side). So what I've done for fill and drain ports is to use the top-facing ports in the top rad as fill ports, and a bottom-facing port on the bottom rad as a drain.

I had to drill holes for the top-facing fill ports from the top rad, but they get covered up out-of-sight when the top panel/ filter-cover is snapped back onto the case. The way it worked out is better than I expected. I can fill my entire loop in one go with only the tiniest bit of trapped air left to bleed out. I'll first open up both fill ports in the top rad, one to add a funnel to fill and the other one to let air out so an air bubble won't get stuck over on that side of the rad, and then before I start filling I'll crack open slightly the fill port in my tube res just to let air escape from it as I fill the loop from the top rad, and I'll close the fill port on the res when the water has filled up into it to the very top and then I'll continue filling up the rest of the loop until the top rad is full.

An added benefit of using the two top-facing ports from my rad as fillports is it gave me an excellent / easy place to screw in a schrader valve and an air gauge so I can air-pressure leak test my loop prior to filling with any liquids. Sure beats putting down paper towels and crossing my fingers I don't have a leak.

As far as the drain port goes I just have an end-plug capped mini-valve into a 90 degree rotary in one of the bottom ports on the rad. It points towards the back (right) side of the case out of view unless I take the right-side panel off. I just make sure the valve is closed, unscrew the end cap and screw into it a barb with a short piece of hose pointed towards a jug/bucket, open the fill-ports to let air in, and crack open the valve to let it drain.

Bottom drain port

Aaaaand, if I get impatient I have a drill-pump I can hook to my drain port and using a cordless drill it'll drain the entire loop in about 30 seconds, more-or-less.

edit:
Another cool thing I should mention about the drill pump (besides the fact that it's cheap - as long as you already have a drill) is that, unlike watercooling pumps, it's self-priming, which means it doesn't need water to feed into the pump. It creates a suction that can pull water through the hose to the pump. That way it helps get out little pockets of water that otherwise usually stay trapped in the loop, and that helps reduce/eliminate dribble when disassembling components from the loop.

Like unicorn hunter I would just put it at the bottom somewhere. I have mine connected to my pump and I just hook up a tube to it with a barb and let it drain that way.

Thank you guys for the suggestions! I may just go with a port at the lowest point of the loop and let it naturally drain, I'll let you guys know what I end up with if I figure something out.

Those are some sweet chain gun fittings you've got there, 15goudreau. I'm looking to use those for my loop, how good are these things?

I love them except for two issues I ran into. I got the 1/2 3/4 fittings which I would recommend under a few circumstances. MEASURE the holes on your cpu block. Mine were too close together so I had to set one up with a 45 degree angled fitting to get it to work. Not a huge deal but was annoying. They do mention this on their website and provide the specifications you'll need, but I didn't see it until it was too late. The 1/2 3/4 do not work with the new monsoon hybrid compression fitting for rigid acrylic. If I had known this I would have gotten the smaller size so when I upgrade in a year or two I don't need to buy all new fittings! Oh well. Live and learn I suppose but at least I can pass on the information to people like you!

So if you measure and aren't going with acrylic I would buy the 1/2 3/4 in a heartbeat they are awesome.

Sidenote if you get colored fittings the paint on the barbs chips super easily. Not that it will be seen but you might want to sand them a little before you install them so the chips don't get caught in your pump or blocks. thumb.gif

Thanks for the feedback! I'll be using 3/8 x 5/8 versions of these fittings, and the CPU block I plan to use has ports on opposite ends, so spacing won't be an issue. I'll most likely stick to flex tubing as well, rigid tubing is just a bit too much work for me. I'll definitely look out for the paint chips, very much appreciate the heads up!
