    Comments about FLUIDMASTER 1021686 Fluidmaster Dual Flush Toilet Valve (550DFR-1P6):

    It's difficult to install. After it has been used for about one year. The cheap plastic dual action handle(painted chrome) broke off. Now, the whole system needs to be replaced. It's not worth the time and money.

        I installed two. The first one failed; the cable inside the unit broke and was unfixable. They replaced it. The second one failed. They replaced it. Now the third one failed. This product is not ready for prime time.

          First, if the plunger on the bottom does not drop freely all the way down,the valve will not close all the time. Something popped inside when messing with the plunger and the float.After it popped,the plunger moved freely and closed fine.
          Second, To fix half flush. The cover on the back slides up and comes off. I scraped a little plastic off the stop inside. Very little and only on the outer side of the stop. It now pulls the cable just a little farther and now the half flush works all the time.
          Last, I moved the water level up to get a stronger flush.
          It works great now !!!!! Nice upgrade.
