    If your water supply isn't capable of drenching your lawn in a limited time period, that is not the installer's fault. It is not beyond the realm of possibility that three hours per zone per week might be needed to keep up with summer heat.

    so should i get larger than a 5/8" meter installed right now before the system goes in to improve flow?

    meters don't matter so much, in comparison to the waterline itself - most modern 5/8 meters are actually a 5/8~3/4 meter, with greater flow capacity in the small package

    I've found changing from a 5/8" meter to a 1" makes a significant difference. Never understood this downsizing 1" service with a 5/8" meter. If the fulls are designed head to head with Halves and Qs then mixing fulls with hs and qs isn't that big of a deal. 2qs +2hs +1 full is 15 gpm. Sounds like the guy who designed this knows what he's doing. No need to come up with a bunch of second guessing. I'd use different products and LA nozzles but his design seems safe. You may have weeks where you need to put more than 1' per week. That is just a weekly average over the whole year but water is required in a bell curve fashion over a whole season. The SL800 is 8 zones right? You won't have an issue getting the water put down in a safe window.

    Unlike in Texas, there's a long run of supply pipe from the street to the house to factor in. Just how long, we don't know yet.

    In our current summer heat waves the one-inch-a-week settings have been left far behind, if you want that shiny green lawn.

    All the more reason to have a 1" meter

    Simply not relevant, if the supply line loses more than 20 psi, especially if they have surcharges to pay for the bigger meter.

    You can find some industry tables for what you can get from different meters and supply lines. It's apparent the supply line is the major factor, especially when you see the combos of one-inch meters and larger supply lines.
