## Questions & Answers

**Q: It says 3/8 and 1/2 bsp  so does it include an adaptor of some sort? I’m after 3/8 bsp fitting**
A: the bottle has a 3/8 inch thread and the nut section into which the bottle screws has a 1/2 inch thread

**Q: Does this fit on the top of the hot water cylinder, i see something similar on mine**
A: The unit does not fit on the hot water cylinder, but on the central heating/hot water circulation pipework, at the highest point. Which is usually near the hot water cylinder, most often by the side of it. Hope this helps!
