Review on 1.5m/60-Inch Soda Club Adapter External Hose with CGA320 Connection (TR21-4 G1/2): Top Choice for External Hose Kit by Kaylon Mackey

May have an odd aftertaste as others have noted. I soaked it in PBW for several hours but it didn't help. As mentioned, if you keep the line clean, the aroma doesn't seem to be produced. My recommendation is to reduce the amount of wasted CO2 to 1. Start with a clean line, close the CO2 valve and dump it through the soda stream if you haven't already done so2. Open the CO2 cylinder valve and fill the line. Close it with a valve.3. Fill the cylinder as usual and try to use all the CO2 in the line. Delete the rest after the desired number of bubbles. There should be no discernible taste.
