Just a quick FYI for anyone out there who may be considering setting up a water cooling system from DIY parts and components.
System in sig. The Danner pump started leaking from the inlet barb threads. I used a nice even layer of teflon tape and had installed the barb finger tight. The reason for this was concern that the housing piece the barb threads into is notorious for cracking when overtightened.
Well, about 3 months after installing the W/C system, it just started sweating a bit. I noticed the water level in my rez slowing going down, I'd have to add a few ounces every day to keep it topped off.
Well, last night it seemed to really be leaking fast. I could actually see water puddling up under the pump. So, I turned off the PC overnight and awoke to a BONE DRY rez. Good thing I was paying attention. Anyhow, I had tightened the barb down with an adjustable-end wrench, and when I did so the housing cracked, just like I was afraid of.
So, I took it all apart, grabbed a tube of epoxy, and went to town. I unscrwed the impeller housing cover, which is where the inlet barb threads in. I didn't want epoxy getting inside the impeller or anything. When I went to remove the 4 screws holding it together, one just spun. The plastic "poles" that extend from the main pump housing, which are threaded inside, are very easy to break off of the main housing. This one broke off trying to UNSCREW it!
well, I just said hell with it and epoxied the whole thing back together to get a really good (unserviceable) seal. When I went to screw it back together, another one broke. Oh well.. more epoxy
.
So, moral of the story is that this pump excells in its NUMBERS on paper, ie good head, good flow, etc.. but, it is a little fragile. I say this as someone who is very careful and gentle with these kinds of things. I'm not some big overmuscling dummy. I did the volt mod on my IS7 before I upgraded, with no troubles... I tell you this just so you understand I have steady hands and am technically knowledgeable..
yet this pump breaks very easily, so my advice is that if you want to get one of these pumps, get some epoxy as well, and when you get the pump use epoxy NOT teflon tape or thread sealer. Also, I recommend you silicone or epoxy the housing together to give some backup to those weak screw holes.
hope this helps someone.
