MTC 250 Skimmer, need help***

fishfinn · Sep 18, 2015

Hi, I haven't been getting too good of a skim out of my skimmer lately so I thought I would clean it and tune it, so I cleaned it, and now I can't get the bubbles to start up again. The air intake part is just spilling out water instead of taking in air. So no bubbles are being produced, Amy help will be very appreciated, thanks

Make sure the beckett is in correctly.

Is the becket the air injector? If so I've taken that apart and put it back together multiple times with the same result, thanks for the help though

Yes it's the air injector. If it's in backwards this might be the problem.

First off, the beckett can not be installed upside down. The lower portion of the beckett is fatter than the upper, and therefore would not fit in the beckett chamber.

Two thoughts:

1. Did you put the ball gizmo back into the beckett?

2. Did you put the lower collar back on the beckett?

Also, and I don't think it would matter (with water coming out), but my MTC has a valve at the hole portion of the beckett chamber to control air flow:

I just went back and looked at your pictures again and noticed water pouring out the opening in the skimmer cup. You must have closed down the drain of the skimmer and now the excess water has to go someplace. There is a lever at the base of the skimmer that opens and closes the exit port of the skimmer. This is used to adjust foam height and wet or dry skimming. Moving it to the left opens the exit port more, while moving it to the right closes it down. If the lever does not move easily, there is a thumb screw below to loosen up the lever. Try adjusting that "valve" and see what happens.

On the older MRC beckett tubes the beckett would fit either way in the housing which is why I suggested checking it. Not familiar with the MTC housing.
