How often should I inspect and replace pipe connectors and gaskets?

Inspect connectors and gaskets every 500 hours for leaks, thread wear, or degradation. Replace NBR gaskets (NB800M.06.04) after each disassembly, and replace connectors if threads are stripped or corrosion is severe. Use thread sealant during reinstallation to enhance sealing.

How do I prevent copper pipe kinking and damage during installation?

Use a proper pipe bender (not pliers) to bend copper pipes, maintaining a minimum bend radius of 5× the pipe diameter. Avoid tight bends and route pipes away from moving components and sharp edges. Install pipe clips at 300-400mm intervals to reduce vibration and prevent sagging or movement.
