Sequence of work
1. When disconnecting the clamping collar, use pliers to press around the circumference of the clamp ring (this will lengthen the clamp) and twist the hose off. Or use a narrow screwdriver to slightly bend the clamp ring.
2. Put a small open end wrench on the end of the hose and wring out the hose.
3. Use screw clamps when connecting hoses.
4. Screw clamps are reusable. Do not use force when tightening - the threads may be stripped.
