What is the small rubber valve on the Saltpipe?
The little rubber valve on the top of the Saltpipe is a back-strike valve, which functions when someone does not exhales through the nose, but blows the air back into the Cisca Saltpipe; the valve strikes back, blocks the way of air towards the pipe, this way protecting it from humidity and vapour. Please do not peel it off. Accidentally, if the valve comes off from the hole, there are 2 alternative simple ways to continue using the pipe. First, you can use put it back on by using cellotape to stick it back on the round end at the same position. Secondly, if you cannot find where your plastic valve is, you can use your finger tip to close the hole when you inhale the air in.
