    I am not an expert but I did 20 psi with air only for 30 minutes. If you go longer then that and the sun heating the pipes can vary the preasure. If you do water then you can go much higher psi and time.

    My locality required 30 or 35 psi. I pressurized mine with water. Just hooked the hose to my manifold and cranked the water on until the pressure got to the right level and the cut off the manifold valve. I had an interesting struggle with my test plugs holding. Boom!
