Install New Fill Valve

What happens here

Next, install the new silent fill valve. Insert the fill valve into the designated hole from the inside of the tank. From the outside, attach the white plastic nut, ensuring it's hand-tightened first. Then, use an adjustable wrench to snug it down further, again being careful not to overtighten. Once the fill valve is secure, attach the small grey flow restrictor (as it matched the old one) into the designated slot on the side of the fill valve. Finally, connect the black refill hose to the top of the fill valve and route it to the flush valve overflow tube.

Goal: Replace the old fill valve with a new, silent model.
