Suburban Brewing

Today my two Polar Ware pots arrived from Northern Brewer, along with a false bottom,  1/2 ball valves and couple rubber stoppers for my carboys. Pots look enormous! I wrapped some teflon tape around the screw pipes and a proceeded to attach the valves to each pot. The first pot went pretty easily, got it tightened well and all was looking good. I did the same on the 2nd pot but I felt screwing the valve was much harder on this one. Afterward I proceeded to fill both pots with water to see if the valves are tight. First pot was fine but the 2nd pot started to leak under the valve; nothing major just dripping a bit. I attempted to remove the valve to see what the problem was but it would not budge! It is basically stuck –permanently attached to the pot. Looks like I’ll need to call Polar Ware.
