So I just uncoiled the tubing and and ran in it the bottom element hole and got it to coil at the bottom.

I used teflon tape and joint compound with a 36" aluminum pipe wrench to put it all together. I will finish the back half tonight. Idea is to braze the coil through a 1 inch bass cap then tighten the union down. I'll post more picture at the right size from now on.

Very interesting approach, all around. Brilliant to use an inspection cam to see what's going on, thanks for the pic!

And your solution to the problem of twisting the copper tubing, by using a pipe union is just awesome.

Great stuff!

Best,
