i had just purchased a pressure flow 1400 and if any one has ever had one i can not get the cleaning handles to move up and down with out a lot of force. i have only tried this on a dry test. i called tech support today and she had told me that the cleaning blade are designed to scrape on the filter media to help remove excess waste. the problem is is that i am really forcing the cleaning handles to get them to move and when i place the filter to where i want to position it which is waste level i can hardly get them to move. tech support told me that i was the only person to complain about this product and if there was a problem with this then it would have never reach the market.so i asked her if a customer was not satisfied with this product that they do not warranty costumer satisfactory. she said this was correct and maybe the retailer would return the product. well he does"t want it because i had to special order it and hagen deals with retailers direct now and not threw there wholesaler. has any one ever dealt with one of these filters and experienced the same problem. yet alone deal with such poor customer service with hagen. not too happy with hagen
