Step 7 · Connect All Water Hoses
You will now connect two hoses to the new T-valve. First, take the original flexible water supply hose (coming from the wall valve) and connect it to the bottom male-threaded connection of the T-valve. Hand-tighten, then snug with a wrench. Second, take the new, smaller bidet hose supplied with the kit. Connect one end to the side outlet of the T-valve and the other end to the water inlet port on the bidet seat itself. All these connections should be hand-tightened first, then given a gentle quarter-turn with the wrench.
