TJ-
how does the tanner tee top attach to the pipe? Does it come with the coupling shown or is that something you added to hold the tanner in the pipe?
HI...it has a "rubber boot" as part of the assembly. This boot is sized to fit over a 3/4" steel pipe. The "boot" looks something like this...
All you do is slide the tee-top into the pipe, and fit the boot over the end of the pipe and you're good to go.
