This was easily corrected by reducing the flow rate.
I would still like to know the formula for determining the effect of flow restriction on PSI. I know there is a formula, engineers have one for everything.
i was sure that extender would have worked. bummer. there is a formula for gpm @ psi static using sized mains but it works on large pipe only i gvess. these gauges are common for use on hydrants for fire depts. see pollard water
