Every inch watered. Every zone that runs.

Pick your lawn and the water you have. The heads go on head to head, the zones are split to what your water can run, and every pipe is sized with the pressure checked at the last head.

Your water

Plan a 30 x 40 lawn160 plans, each checked head to head

Your water comes first.

PSI --

A $10 gauge on the outside faucet, everything else in the house off. That is your pressure.

GPM --

Time a 5 gallon bucket at the same faucet, wide open. 300 divided by the seconds is your flow.

Those two numbers decide how many heads a zone can run and whether rotors will pop up at all. Every plan here is drawn for one pair. How to measure.

No dry corners.

Head to head means every head throws all the way to the next one, so every spot gets water from at least two. Quarter circles in the corners, half circles on the edges, full circles in the middle.
