Practical installation and care tips
- Ensure proper alignment of End 1 (Fine Threaded) with the corresponding supply fitting and End 2 (MHT) with the hose thread connection.
- Use appropriate thread sealant or Teflon tape on male threads to promote a snug seal without over-tightening.
- After installation, check for leaks and operate the line to verify smooth flow and backflow protection.
- Periodic inspection is recommended in outdoor environments; replace if threads show wear or the unit leaks under normal pressure.
