The FUMO purge valve is a genuine accessory developed by FUMO to use your hookah as a multi-hose hookah.
The FUMO purge valve functions on the same basis as traditional hookah valves. A multi-direction will block the air flow when the hookah is used with another hose.
All FUMO hookahs are compatible with the purge valve.
If you do not have a purge valve on your FUMO hookah, do not blow into your hose without taking off the glass valves before, the water may come back up the stem, and drown your tobacco and coal!
