No kidding.
I had a number (three? four?) systems built with these and they all cavitated a bit. You can stick a bit of open celled foam in there (the material eheim supplies as an intake filter for their submerged fish pumps works great) or a bit or rolled up nylon screening (use a heatgun or some such to fuse the exposed ends so you don't end up with a loose screen "wire" loose in your system).
Or you could just go for an updated innovatek reservoir. They're made of ABS, but they're alco solved the cavitation issue. The problem there (for your setup) is that the inlet is moved to the top.
Oh - high speed PC's got 'em back in stock. |
Since I said I did the tests in the bathhub without the Reservoir even connected and the pump fully submerged I do not think that is the issue... I first thought it was cavitation because it would stop for a small while and then continue if I tilted the case, though I now attribute that to voodoo magic :P
I still think it is strange because from AquaComputer you can buy very restrictive waterblocks yet they only offer a Eheim pump as powerful as mine is (1048)
The reason as I said my Eheim 1048 rattles is too restrictive waterblocks not anything else as I previously thought...
