A little annoyed with a Koolance reservoir...

post #1 of 13
Thread Starter 
So I purchased a Koolance RP-402x2 reservoir a few months ago for my dual MCP35x pumps. I also purchased a 180-degree connector for the back so I could run the pumps in serial.a

I wasn't in any rush so I had a custom faceplate created for me and had Jim at Case Labs powdercoat the connector. I was using a different computer for the time being.

Once I took my computer apart to use the new reservoir, I noticed that the 180-degree connector was leaking. I couldn't for the life of me figure out why so I RMA'd to Koolance which was very smooth. They shipped me out a new piece immediately without even taking the old one back. This was great service.

However, while waiting for that connector I chose to just use one pump. I plugged up the two holes that the 180-degree connector would use with fittings and was on my merry way for a few months up until yesterday.

Yesterday I moved all my components into a new case. Yay! I put the new 180-degree connector on the back and filled up the reservoir to test it. Low and behold, it also leaks. Sure, it's very slow - but it does leak. It drips out the bottom right outlet. I'm not sure what to do at this point. Apparently FrozenCPU nor Koolance even sells the 402x2 anymore and I am forced to believe that the reservoir is at fault.

What should I do?

It is leaking around the fitting? Not sure by what you mean by leaking out of the outlet.

If it is leaking on the fitting use some Teflon tape on the threads.

I had this exact same problem. It's caused by over tightening the 180s. I am a nut when it comes to tightening and I have the scabs on my fingers from my last build to prove it. biggrin.gif

Remove the 180 connector. You will probably see that the gaskets have receded into a small groove which I think it meant to hold them in place.
Remove both gaskets. When you bought the kit, you should still have all the parts from the pumps. Mine came with some barbs with tiny little gaskets. Place the smaller gaskets on the 180. They should just about fit into the grooves. Then replace the factory gaskets and reinstall.

Mine has been running for over a month like this with no drips. Let me know if this works for you. thumb.gif

The reservoir I believe is the latest revision, 1.2. The connections are indeed tight. There is definitely a physical problem.

Originally when I had the 180-degree connector powdercoated, it was leaking both from the hole where the o-ring is supposed to seal as well as leaking from the connector itself where you screw it in. I originally believed the powdercoating process may have damaged it. I'm not sure at this point. The new connector is leaking strictly from the supposedly sealed o-ring connection. I haven't tried plugging in it up top or backwards to see if it's the connector or the hole itself yet. That will be a project if I have time tonight to deal with this.

I'm not too crazy when it comes to tightening, but boy is this one annoying. I do get blisters on my fingers though when working on a new project mainly due to the constant removal and addition of Bitspower fittings! thumb.gif I'm not sure what you mean when you refer to the gaskets and the groove. It sounds like you're talking about o-rings? I know this is a long shot but do you happen to have pictures? Last night was the first time I used the brand new 180-degree connector. I tightened it up as tight as I felt necessary and then filled it. It very slowly dripped. I loosened it a bit to make sure, but it just dripped barely slightly faster. If you could let me know what you mean about these gaskets I would be happy to give it a whirl.

Sorry, you are correct I was talking about the o-rings. I pulled a couple of tiny ones off 2 barbs and installed them under the factory o-rings from Koolance.

I was talking car stuff with a co-worker and got stuck on gaskets.

No worries! So you left the factory o-rings on the tube but also added smaller o-rings? You didn't just take the factory o-rings off and put on different o-rings?

I'm surprised that worked. I'm not sure if I'll be able to find the barbs you are referring to but I think that's ridiculous if they can't ship the part with the proper sized o-rings.

I have extra o-rings so I'll try them and see along with flipping the piece over to see if it leaks from the same area on the reservoir. If it does, I guess we'll see. Pretty stupid stuff.

So I flipped the piece over last night and didn't see any water or droplets coming from either of the holes.

I'm still really skeptical to put it into my machine this way but I mean it's not leaking right now. I don't know how that makes any sense.

Can't agree more. I love the reservoir but that 180 fitting is not the best. I really think it's just a manufacturing defect. When I took mine off the first time after wrestling with the leak, the o-rings were nestled into grooves on the screw fittings. I think that the smaller o-rings just keep the larger ones from settling into that groove when you tighten the fitting.

It's a ghetto fix at best, but mine has been running like this for over 2 weeks now without so much as a drop. I think you are correct. Slightly larger o-rings would solve this issue as well, but my local HomeDespot is desperately under supplied in this area.

If you can run the loop with the 180 in place and your pumps on full blast that is probably the only true test to see if it will leak.

Let me know how it goes.

If you're scared of it, you can always use plumber's tape to be 100% sure.
