I've read of other memebers saying that the autoseal hose ports on Mya's as well as Syrians, aren't that great. That's why most of the time we recommend people to just get a single hose, since it will have a muchbetter seal. Anyway, you can try and get in contact with Mya (site below) and see if they'll send you the port plugs. It's this little shiny piece that screws into where the other hose ports are coming out of. This way you can convert it to a single and test it. Just out of curiousity, how new exactly are you to hookah smoking? Is this your first time setting it up yourself and smoking?
