Step 5 · Install Water Supply T-Adapter
With the bucket still in place, use an adjustable wrench to unscrew the existing water supply line from the bottom of the toilet tank's fill valve. Next, take the supplied T-adapter and ensure its rubber washer is properly seated inside. Screw the top of the T-adapter onto the toilet tank's fill valve where you just disconnected the supply line. Hand-tighten, then give a quarter-turn with the wrench. Reconnect the toilet's original water supply line to the bottom connection of the T-adapter. Finally, connect one end of the new bidet hose (supplied with the kit) to the side connection of the T-adapter and the other end to the water inlet on the bidet seat itself. Ensure all connections are snug.
