Greetings all, This is my Paroneli, my first acquisiton: She seems to smoke fine (from my limited experience) and I have been enjoying several bowls a day since I purchased it less than a week ago. The kind owner of the local tobacco shop showed me the basics of bowl packing and cleaning care before I left the establishment. When attempting to thread with a pipe cleaner, he had to remove the stem to complete the threading. He told me to be cautious of removing the stem too much, as it may loosen the seal. Secondly, he informed me to always turn it the same way, and of course, never remove while hot. I've cleaned her several times since then, and with each attempt the pipe cleaner will not go through without removal. Every time I attempt to thread it while intact, it "hits" near the bowl and cannot complete the run. Looking at my picture, it seems it may simply be curvature of the design itself lending problems. my questions: Is needing to remove the stem almost daily going to damage my pipe as he suggested? As a result, is this pipe actually defective? I am going to speak with him today. gathering info ahead of time, however, as I want my investment to be a sound one conducive to years of use. Most importantly, I would like to know now if this issue warrants it being returned. thank you.
