This fill valve replacement kit works with most standard residential toilets and connects to a US-standard G15/16 in. water supply line. Its height adjusts smoothly from 8 to 13 in. to match different tank depths. The kit includes 1 adjustable fill valve and 1 2 in. flapper, both designed for reliable operation without tools or plumbing expertise. A V-shaped silicone seal on the valve base creates a tight fit against the tank bottom, while the flapper uses corrosion-resistant rubber that stays flexible over time. Water level in the tank and bowl can be fine-tuned independently using simple manual adjustments. The valve delivers consistent refill speed and volume, reducing noise during refilling and preventing common issues like slow filling, constant running, or intermittent leaks. It supports efficient water use by minimizing overflow and unnecessary cycling, contributing to lower consumption without sacrificing flush effectiveness. Installation requires only basic hand tightening and takes under 10 minutes for most users.
