1. Be sure that plug valve is fully opened. Heat the tube first. Then, transfer the heat from the pipe to plug valve as much as you can so as to avoid the prolonged heating time of plug valve itself.
2. Use cloth or steel wire brush to clean pipes and cutting parts to make the metal surface bright. Steel wool is not recommended.
