The multifunction handle is unique to the Ecco filter. In addition to locking and unlocking the filter and use as a carrying handle, it functions as a priming device. The filter comes complete with media, fittings, and valves. The convenient interlocking media baskets allow for versatility in media setup while preventing water by-pass. The intake and output hose attachments are designed to swivel 360 degrees to ensure kink-free hose connections.
