I realize 2" is the recommended size for the Fafco headers. But our plumbing here at the cabin is only 1 1/2" so wouldn't getting 2" be useless? We planned on using 6 4'x10' panels. Which they said would really be 12 2'x2'? I was ready to 'click' and then had these doubts.
What we're after is a permanent setup. Ground rack. Vertical drainage. Goldline Controller. Thanks.
