Rated 4 out of 5 by Replacement air vent Needed a replacement for a failed air vent. Did the job perfectly. 2 Jun 2016
Rated 5 out of 5 by Bottle Air Vent Bought this to replace the one supplied with the water tank which failed under pressure. Easy to fit, the one way valve made it possible to fit even with the tank virtually full as I could swap it quickly 13 Oct 2014
Rated 5 out of 5 by Simple An effective replacement for an old leaking unit, simple to fit (don't forget the PTFE tape!). 22 Oct 2012

Comes as two parts.

This item comes as two separate parts. They are shown already joined in the picture. I assume that I connect both parts together in all instances but just wondered if there was ever a time that the bottom section is missed off otherwise there would seem to be no reason to make it separately. The only thing I can figure is the base part can be fitted first then the pipework filled, the base part seems to form a water seal until the bottle is screwed on and then the bottle becomes "live" ...........Have I figured it out myself or does anyone have any more experience ?

Answer: 
This is just due to the design of the product that it comes in two parts, there is no practical functionality for it.
