Totally agree. Irritates the hell out of me when I see irrigation systems running 1.25".

The soils steady state infiltration rate is what will determine the maximum workable PR.

Before you look to design a system to apply as much water as fast as possible, you need to determine the above.

For most all postage stamp lots, that is usually (not always) sufficient.

I see these 3/4-inch poly supply lines, and I imagine what they might do if subjected to the same sort of hammering that copper handled.

That's BS. One should know exactly what they are bidding, designing and installing without the input of a third party.

My youngest daughter ran the commercial counter for a major parts store. Does she know parts? Yes. Can she rebuild a motor? No.

Why chance a guess? Do a flow/pressure test.

Typically I see 12 gpm at 35psi/9ish gpm at 48 psi off 3/4 supply, 5/8 meter. I measure after zone valve to account for all losses accept lateral piping

The meter is 3/4x5/8. That's what's stamped on the top. The manufacture says its a true 3/4" meter.. the supply is also 3/4 poly pipe.

5/8 = 15 gpm @ 75 %

3/4 = 22 gpm @ 75 %

I would run the gpm/psi first but thats me.
