[chbot] Filler for waterproofing temp sensors

[Mark Beckett]

Way back when I was fixing Wright Spa pools they had a similar device in 
a stainless tube.

We simply used some thermal paste, bunged it into the stainless sleeve 
and resqueezed the end and added a bit to heatshrink.


The stanless tube went into the filter housing and used a compression 
gland to stop water escaping.
