After spending hours upon hours bent over installing the Wirsbo hePEX tubing for the slab zones,

I felt the installation of the staple up under fit zones was going to be a piece of cake. Oh how wrong one can be. Besides taking three times as long

to install, and twice as difficult to manage the tubing, the degree and intensity of neck pain one experiences, from constantly looking up, far exceeds any

lower back pain caused from bending over during the slab installation. I would not recommend this for someone who has a 3-1/2" Steel

Plate and 6 Titanium screws in their neck, but then I won't tell my orthopedic surgeon, if you won't. What he doesn't know won't hurt me.

After completing the underfit, I started constructing the Radiant system control board, all the while asking, WHAT THE HELL DID I GET MYSELF INTO!  Oh well, must move forward…..
