[EDIT2] (at top to make sure visibility) All good, as explained in one of the posts. I shouldn’t expect pressure regulator to work directly at faucet. (Use tee or splitter) Here is video https://youtu.be/gp4aquT19LA

[Just started looking into drip irrigation] I’m using rainbird 25PSI pressure regulator along with pressure guage. (https://www.amazon.com/Rain-Bird-HT07525PSI-Irrigation-Regulator/dp/B0049C5FZA)

Pressure guage measures about 70PSI without regulator (directly at garden faucet), however this doesn’t really change even after using pressure regulator.

Am I misunderstanding pressure regulator? or is guauge/regulator broken?

[EDIT] Here is what I’m talking about (in both cases it reads about 60PSI):

    @SchmidtGenetics @rando my tap pressure had always been around 195. I now have 2 regulators inside house that I never needed before I got a new hot water heater. Incredible outside pressure, have to be careful with soaker in garden.

      Pex is rated at 120 psi at hot water temperatures and only 160 psi at room temperature. So I seriously doubt that.

        Rated pressure != burst pressure. I would expect a line rated at 160PSI line pressure to withstand at least 200PSI before bursting.

        Water hammer can drastically increase line pressure; a line rated at 160PSI should be able to handle the transient pressure spikes that commonly occur in a 160PSI line.

        Deliberately pushing 200PSI into a line rated for 160PSI is certainly not safe or acceptable, but I wouldn’t be surprised to see it hold, and I would be surprised to see it fail.
