What to check for this reel

The 8-inch pink-emitter tape needs 6.0 GPM for ten 100-ft rows at 10 psi. That is 2.0 GPM more than the 12-inch pink-emitter tape over the same total length.

Example zone demand

10 rows of 100 ft each would need about 5.40 GPM at the listed 8 psi. Check the flow available under pressure and the manufacturer’s run-length chart for your longest row and slope.
