A pressure rated pump would be Blue line, iwaki, or reeflo. A mag 18 pump is not a pressure rated pump. Is the skimmer above your sump water line?

 

[nuccadoc]

I am not using a pressure rated pump. It is an off brand from China. The skimmer is above the water line.

Make sure the unit is clean, change out the cotton in the air intake. It's going to take some dialing in, but I would make the water line about half way up the riser tube and then just adjust the air. I think you might have the water level to high. Try that first. When you have a chance pick up a good pump, such as a blue line 40. You can get them used. Then you will get the performance you were looking for.

I thoroughly cleaned the unit before starting it up, it's only been running for about two weeks, and the air intake is brand new. I can shut off the valve completely and there is no difference in the bubbles produced. I can also remove the air intake completely and put my finger over the hole and there is still no change. The water level is set to 1 inch above the box.

I'm stumped... The only other thing I can think of is your pump. I would give MRC a call, I'm sure they could tell you what is wrong.

 

[nuccadoc]

LOL! I am too! I will call them tomorrow and post what they recommend. Thanks for your help.

 

[davidtsx]

Definitely do, now my bothered. LOL

if you shut off the valve, cover the airhole, and still get bubbles you have an air leak, try listening at the top of the injector to see if air is leaking in. You might need to replace teh gasket up top.

Sounds like a air leak try putting tape around connections to make sure you have a good seal

having problems with mine. a week since I cleaned it. foaming at the neck, but no skimate in the waste collector.

Tried that. I'm going to clean the skimmer cup again tonight.

 

[RGibson]

what size is the drain line from the cup

 

[GPhiAce]

Great to get this thread up agani. I have a MRC 2R with an iwaki 55rlt. This skimmer is a beast. Love it and it has only been running for a week. Looks like milk in the column.

 

[newsalt]

what size is the drain line from the cup

1/2" I.D. There is a level of dark brown skimate in the collection cup right up to the drain connection. It never gets any higher to overflow into the waste collector.

 

[RGibson]

can you post a pic of the collection cup.

 

[newsalt]

can you post a pic of the collection cup.

I was actually going to post pictures of the whole unit to show how it's piped. I'll include a close-up of the collection cup. Will post pics tonight when I get home from work.

I was able to get some photos at lunch. This link should take you to them:

I called MRC and sent them photos and video and through discussion with them found out that I am missing the gasket for the flange on the becket injector. They use the seal for a 1" bulk-head so I will either obtain one of those or make my own. Hopefully this will take care of the problem because I have no control over the amount of air that enters the skimmer.

 

[trueblackpercula]

just get a new injector and check hkur gasket on the ljd of the skimmer cul.
