Portable Chiller for ICE COLD Showers for Wim Hof cold exposure - Part 5: Add the Recirculating Pump

In this video I show adding the recirculating pump, including making-up some PVC connections to the heat exchanger. I then assemble the chiller with the pond liner and the pump in the pond liner (reservoir). And I show adding the air switch that the user will push to activate the pump.
In case this is your first time here, the "problem" is that the showers in the summer in the Piedmont of the Carolina's are over 80F (that's 27C), so NOT cold!! My solution is to use a cold reservoir and pipe the fresh water source through a heat exchanger which pulls heat out using the cold reservoir. I've been running a built-in cold shower machine for years, and I'm finally building-out the portable version. I bought the parts for the build, but never (until now) did anything with them.
This is the fifth in a multi-part series that I plan to complete by the end of May 2024.
