Typical Perforated Clamp failure Mode

This is just one of many perforated clamp failures I come across, and one reason I no longer trust my vessel, or customers vessels, to them. This clamp was a single clamp, not one of two as it should have been. It was installed on a galley sink drain. The hose was weeping/leaking because the single clamp had "slipped" and let go. If that hose had fallen off the boat would have sunk. Luckily the owner was only faced with a murdered $800.00 AGM battery bank...

To recap, make sure the hose adapter is long enough, use two clamps for below waterline applications and consider using a higher quality non-perforated clamp such as those made by AWAB.
