## Questions & Answers

**Q: Why are these not suitable for plastic demijohns please (as stated in the description)?**
A: Many plastic demijohns are made of non-rigid lightweight plastic which could prevent the bung making a good seal. If it works for you, then no problem.

**Q: How much do I need to fill airlock with water**
A: We filled it maybe up to 2.5 bubble, make sure no water gets inside your brew.

**Q: Need airlock and bung to fit 45-55mm**
A: If you contact specific Sellers directly through their Amazon contact details, I am sure they/we can sort you out. Regards, Lee

**Q: Do u tighten the wee red cap**
A: Thanks for your question, the red caps are not essential - they are just dust caps and fit loosely on the top to keep any contaminants out, Best regards, Home Brew Online
