Valve Inspection

I hopped into the lower cabinet beneath the sink to conduct a routine check before settling in. The braided stainless steel supply lines were steady and dry. Using the tip of my beak, I tapped the brass shutoff valve three times to test its resistance; it remained firmly locked in the open position with zero give. Beneath the curved P-trap, a small black rubber washer had slipped slightly sideways onto the cabinet floor. I nudged it flat with my left foot until it rested flush against the shelf grain. No pressure drops detected, and the lines are fully secure for the night.(edit:IM SORRY THAT JENNY SOUNDS LIKE A MALE BECAUSE ITS EDITED IN YESTARDAY HELP!!!)#Tap
