Need help getting Bak Pak 2R to work

[jasontk]

I received a Bak Pak 2R recently and it's was working great for a while but I have since moved it around a bit and now I can't get it to skim at all. No matter how far I push the collection cup down into the water or how high I raise it I cannot get the bubbles to overflow into the cup. All of the bubbles are busting too low in the funnel so they cannot be pushed over.
What would be a reason for this?

Did you wash the riser tube or is there any oil or anything that would prevent the bubbles from rising up the tube. Is the pump clean and operating correctly?

I have not washed anything yet since I received it used, and very clean, a few weeks ago. Just a few days ago the foam was overflowing like crazy and now it suddenly won't rise at all.

Just did.... no luck
I'm just going to let it run like this for a while and see if anything changes.

Try messing with the amount of air bubbles that are coming out of the intake. Mine does this every once in a while and sometimes I have to take the hose off because there is some salt build up in there . good luck

1. open the air valve all the way.
2. put the collection cup so that the bottom lip is just BARELY underwater.
The way you describe things in the first post, it sounds like its working just fine to me. Give it some time.
