I went to finally put together my watercooling rig last weekend(only about 6 months behind schedule
). So after getting everything prepped, I decide to check out my Danner MagDrive 5 pump just to make sure it's in prime condition. Put it in the sink and I notice water shooting out of the back of the impeller housing. Upon taking it off and examining it I notice that it has THREE huge cracks that originate from the input on the housing and radiate out towards the screw holes. I was using brass fittings, but I had a large hose clamp over the input housing(the cracks started immediately after this). I only finger tightened the fittings, so I don't think that was a problem. Most likely it was some drunk person kicked it and managed to generate sufficient torque on the fitting to pry the housing apart.
Now my concern is that if the housing was this easy to break, there must be a chance that this could happen inside my case. I'm a little wary that I could jostle my case around and then find an electrified aquarium on my desk.
Are there any other ways besides the hose clamp on the input of the housing to keep it from cracking so easily? If there is no better way I might just get an Eheim pump.
Also, do Petsmart stores carry replacement impeller housings for Danner pumps? I know the online store does, but does anyone have experience with the physical stores?
Thanks for any replies.
BTW.. The engineer who designed the injection mold for the impeller housing should be shot. There are no structural support ribs and the plastic is much too thin to survive any amount of force placed upon it.
