## Questions & Answers

**Q: do you leave the valve body in an open or closed position**
A: Open position as it allows any air to escape. Closed position should be used if valve needs cleaning

**Q: Can you use it for 1/2-inch bsp connections? from the product description you can because it comes with a 1/8 to 1/2 adaptor - so does this one?**
A: Mine was a straight replacement so not sure of the connection size

**Q: Description, box and instructions claim it can be easily serviced by unscrewing the top. I cannot move it and it looks like its one solid part?**
A: The top of the valve should screw off like a jar lid.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Superior air vent
*by D***H on 10 October 2015*

I have an unvented heating system which has complex pipe runs due to the age of the house. So, I need quite a few venting points. I have tried various automatic air vents and they either leak under the 1.5 bar pressure of the system, or get blocked and don't vent. These just work and I won't buy another brand now. Feature one: twist the body and it seals off the bottle so you can maintain it (never needed to do this in 5 years of using them). Feature two: the vent cap has an expanding fibre washer which closes on contact with water and so, in the unlikely event of a leak, you won't have a soggy ceiling...Top rate piece of kit.

### ⭐ Totally useless item.
*by M***. on 12 April 2024*

If you have air in your system DO NOT BUY THESE UNITS THEY ARE USELESS!!!!! I had bought 6 of these and not one worked. Buy the £13 brass ones which work faultless. These Honeywell ones have to small a float fitted that don't allow the vent to open under pressure of 3 bar. Avoid at all costs!!!!

### ⭐⭐⭐ Not Honeywell Branded Item
*by S***M on 15 October 2023*

This is some generic (German made) part - time will tell if it is any good; it is NOT a like for like (brand). replacement.
