Newly installed kitchen with sprayer No-name, not the cheapest on the display, but < mid-price
Opened up the valves after install, listened and watched for leaks for 2-3 minutes, absolutely nothing! Turns out I celebrated too early. Ran both sides, tried the sprayer, cleaned the crap out of the screen, all good. Turned the handles off and heard the drips, did a quick newspaper test and pinpointed them as coming from the cold handle. Tightened up the connector there, but that's not it. Only a small amount, and only when it's open, and it's not slop splashing from up top.
Where am I going wrong? Thanks in advance for any help.
