got one of these at lowes for $10 (which i returned after haha). hooked it up to my washer hookup which was where i tapped the water line. i had about 65psi out of there. it worked fine with the cheaper emitters, but when i got these blue ones it kept blowing off the cap
so i installed the regulator and its been fine ever since
