ok, not a lot of answers to the question about the impeller or the leaks, so maybe someone can advise if they have any suggestions in properly setting up the filter.
First let me say thanks to anyone who has offered a suggestion to the other problems.
Problem 1: very noisy filter. narrowed it down to the impeller, took it apart...discovered when they assembled the impeller, they forgot one of the rubber endcaps that stabilize the impeller. Slap the knuckles of eheim.
Solution: went to City Pets in Houston and picked up the shaft and two rubber caps for $8.99. Hopefully that solves that one. Although the impeller magnet does have a little chip on it...probably from banging around in the chamber. If the rubber cap doesn't fix the noise, new impeller $20. That would be another be slap for eheim.
Problem 2: Sometime during the night, the filter leaked. It seems to me that the pressure built up in the filter and it leaked around the primer pump. I can tell you that I didn't use the green intake/output, but instead used the intake/output from a magnum 350. I guess it is possible that the use of the magnum pipes caused an undue pressure on the filter. However, I just conmpared the two and they are the same diameter etc. Actually, I would think there would be less pressure since the magmum output is a open, split diffuser instead of a spraybar. I also primed the unit several more times after it was running. This released extra air...and didn't seem to have any ill effects. In fact, I reread the manual and it says (after the step to start the filter) that the priming support can be activated repeatedly. Anyway. Any comments here?
Ok, now for help setting up.
Layer 1 - ehfimech tubes in the bottom basket...blue coarse pad on top...underneath collapseable handle. Stem gasket in place.
Layer 2 - ehfisubstrat in basket, stem gasket in place. Input tube inserted in gasket. I don't use the carbon pad so no filter pad in basket.
The directions say to put the white (fine) pad on top of the basket...on top of the handles. In my opinion, this doesn't fit well since the white pad gets crushed between the handle and the green lattice piece. (In one pic, I pressed the edges of the pad down into the basket so that the pad is below the gasket on the basket tube.)
Interesting enough, the booklet says:
Attention: The white pad must not lie under the handle, the cutout for the pipe opening must remain free.
I don't exactly know what they mean by the 'cutout for the pipe opening' must remain free. How would it NOT remain free? Of course the opening in the pad must go over the pipe, but it seems the overall package fits much better UNDERNEATH the handles. Nonetheless, I have always followed the directions.
Lattice: The lattice fits over the last filter pad. This becomes very tight. The grey stem is inserted into the gasket of the basket. The filter fits down onto this tube....but there is no additional gasket.
Any insight here...before I give it another shot?
Thanks
Rob
