New to brewing and this forum. Decided to try brewing for the first time with a Mr Beer kit. I also have another unused kit and have a problem with both fermentors. Both have a very slow leak at the spigot. It takes several minutes for a drip to develop, so I know it’s unusable that way. I’ve tried tightening the nut inside to varying degrees but still no go. I have tried calling the Mr Beer help line and chat, but no one seems to be answering, possibly because of Covid-19. Now for my question. Is it ok to use a silicone sealant (food grade)on the outside sealing washer to try stop the leak? Any other suggestions? Thanks.
