PRO-TIP: Over time, and with exposure to some chemicals and dust (if dust caps are not left on), the inner core of the valve can become dry and difficult to turn. Simply squirt a bit of liquid silicone up the spout of the flush valve, and lubricate the valve with a few turns, and it will be good as new.
