Hello I am new to this forum and find the information very helpful. I have done about a dozen installations all using city water supply. I have someone that wants a job done but they already have an existing well. My question is that I tested the psi and gpm at the spigot. the psi was done with a gauge and gpm via the bucket test. Is this an acceptable place to take these readings for my design. From searching the internet I see some people actually tie into the water line right after the pump to take readings. I find this a lot of work to give an estimate and don't think most homeowners would want you to do that just to get a quote. They had two quotes already one guy tested same spot I did and the other never even looked at the pump well or turned on the water. any help would be greatly appreciated.
