Make sure to screw on the retainer clamp... but not too tight. It's only there to prevent the tubing from walking in the housing, which can cause it to get eaten up. Do'nt clamp it so hard it leaves marks. When you're done using the pump remove the tubing shortly thereafter, leaving it clamped can dent the tubing permanently.
