Step 7 · Install New Valve and Reconnect Discharge Pipe
Once the new valve is hand-tight, use the pipe wrench to give it another one to two full turns. The goal is to make it watertight and position the valve so its outlet is pointing straight down towards the floor. Do not overtighten, as this can crack the valve body or damage the threads on the tank. Once the valve is installed, re-attach the discharge pipe to the valve's outlet. Hand-tighten the fitting and then give it a final snug turn with the pipe wrench. The pipe must terminate no more than 6 inches from the floor and should not be threaded at its outlet.
