Finerfilters press button chrome water spout 

I purchased this, online, because the water spout was exactly what I needed to provide a fresh water supply for cleaning teeth and for drinking water in a bathroom. I have 2 cold water feeds, one for handwashing as it was from a water storage tank and the other off the mains for teeth cleaning etc.
When I received this, I really liked the quality, however I was in no real hurry to install it as the bathroom was still in the design & construction stage. So, when I was ready,

Initially, I emailed, was told they don't have any connections to a 22mm BSP. So, I telephone and explained it need not be to 22mm BSP fitting, but I needed to be able to connect to bottom of the threaded shaft of the fountain which had a 6mm compression joint, but with no olive supplied. I asked for suitable connections to finally  connect to 1/2 inch BSP threaded connection. I was completely blanked out by their representative, and even though l explained exactly what I needed, the person I spoke to was extremely unhelpful and didn't want to know. 

I am not a novice at plumbing, but as consequence of the lack of help from fine filters I have now spent 3 months trawling the Internet & visiting plumbing suppliers trying to find suitable connections. I found a motorhome builder who spent time trying to assemble plumbing items, and when he was unable to do it, he suggested trying a hydraulic company.  An agricultural vehicle parts specialist also spent time researching solutions. and was able to supply an olive for the compression joint for just 59p! I have now assembled the four items that are needed to connect the fountain to my sink, but no thanks at all to fine filters who have been no help whatsoever!
