Hey everyone,
I have a small plumbing shop in southern CA.
Regarding single family detached residence . Municipal city water supply, no well water involved.
I keep noticing inch and a quarter pressure regulators installed from the builder, BUT the water meter is only 1 inch.
I have also seen 1" regulators and main shut off valves attached to the home with 3/4 water meters.
Isn't the total overall available flow rate dictated by the source ?
Seems simple to me.
If the flow from a 1" meter is X at X psi then upsizing the pipe from the meter to the home can't produce additional volume. ?
It may reduce working volume at a fixture, but static pressure would still build to capacity and be whatever the city pressure is at the regulator and whatever the set pressure is after the pressure regulator.
I'm thinking that the Municipal water department installs the meters sometimes well before the developer builds the tract, but it doesn't seem to make sense to use larger more expensive material than the meter supply itself.
What started this ponderance is why go purchase an 1 1/4 regulator when I can get a Wilkins 1" 70 for half the price if the meter is only one inch?
I look forward to the opinions and education if I am missing something.
Thanks
Giovanni
