>> ... I set the drip tape system up about a week ago...and it's been raining ever since then!
Just like carrying an umbrella assures a sunny day!
Interesting that the drip tape "curls" even after lying in the sun for a while. You finally got a big roll of the 15 mil tape, right? The sturdiest?
Does it also twist, or do the emitters stay pointing up if that's how they started?
I agree that tugging on the ends SHOULD keep it straight.
Nice to have permanent, underground PVC pipe!
>> Got 200' of 3/4" sch40 for a bit under $45 tax inc.
Hmm, nominal 3/4" Schedule 40 has:
an OD around 1.050"
Wall thickness around 0.133"
So ID is around 0.784"
According to this calculator, you MIGHT be able to push
8 GPM through that 0.784" ID (480 GPM) and only have a pressure drop of 6.4 psi per 100 feet.

But usually, people quote "240 GPH" for nominal 1/2" polyethylene pipe, 0.600" ID .
and
480 GPH for nominal 3/4" mainline, 0.830" ID .
So you might get somewhat fewer than 480 GPH due to turbulent flow and pressure drop.

primer and solvent cement.
I don't know if this is true, but I saw it here:
