I bought a simple pressure gauge with a female hose fitting to test my water pressure at the end of the hose. It read 66psi. I measured the water flow as well, it was just shy of 6gpm. I then installed the pressure regulator, which is rated for 25psi between 1gpm and 15 gpm. I put the pressure guage on the other end of the pressure regulator and turned the hose back on. The guage then read 39psi.

This is higher than the drip system recommends and I wanted to know if I'm doing some wrong, my assumptions on how it would work are incorrect, or if I have a faulty piece somewhere.

Thank you in advance for your time.

A possible minor concern, but if your irrigation shuts off there can be a backfill into the house water supply from unclean irrigation hoses. There is an attachment that can stop that. It might be part of your irrigation kit, but maybe not. They are cheap. It is just a small one-way valve thingie.
