I built a CFC out of copper tubing and a rubber garden hose. The first time I used it I got a clog after about 2 gallons. So I bought a cheap pump and built a hop spider before my next batch. Testing it out before hand, I could pump hot water through the CFC and back up into the kettle easily. I made a video to show a friend:

As shown in the video, I would like to feed the wort through a pump, then the CFC, and back into the kettle.
During my next batch, I had the wort recirculating for two or three minutes perfectly. Near boiling wort in and cold wort out. Then it stopped. I flipped it over to run wort through in the opposite direction, which cleared the clog, but then it clogged again. Flipped it back to the original orientation and it wouldn't go. Back to the IC.
I only used 1 or 2 oz of hops and using the hop spider there was very little trub left when I transferred to the fermenter. So I don't think "too much trub" is my problem. Perhaps a stronger pump? There is one bend that is less than perfectly smooth, though I wouldn't call it a kink. The wort makes it through ok for a little while, but maybe over time a little trub collects.
I really dislike using an IC because the tap water is too warm during the summer to really get the temp down. At the same time, I don't want to sink a bunch of money into fixing the CFC without really knowing what will work. So if anyone has any other ideas, I would be greatly appreciate it.
