I am getting incomplete flushes on my Mansfield 1.6gpf toilet. The float
valve drops after only a few seconds. When I take the cover off and watch a
flush, it only lets out about 10% of the water before the float valve drops
and stops the flush. There does not seem to be anything pulling down on the
valve. Any ideas as to why this is happening?
The water level is set properly and I have the supply water valve open all
I had such a problem one time. The cause was the washer at the bottom of
the "plunger", the part that raises, had popped loose. I simply reached
into the tank, raised the plunger by hand a couple of inches and pressed the
little sucker back in place. Two fingers on each side of the bottom of the
plunger and press up. I have 3 of them in this house and that one time with
the one plunger is the only problem I have had in 11 years.
Larger loads do require a hold of the lever with just about all of the 1.6
Let me know if this works for you.
Unless the design has changed the Mansfield line does not use a flapper.
They have a part that resembles a household plunger. There is a gasket or
washer inside the plunger that stops the water flow when it sits down on the
seat of flush valve. This entire part is raised no more than 2" when the
handle is depressed. When the washer is properly seated it continues to
hover long enough for a flush to take place. When the washer pops loose it
closes much more quickly.
I just went looking for a picture to post or refer to so I am going to
modify my statement. First the picture:
From the picture it appears that the washer is attached to the bottom
portion of the valve. Whatever I pressed back into place was inside the
bell shaped part. Maybe that piece is made in two parts and snaps together.
I inserted my fingers on each side and slightly above the pointer line for
#M001. The entire plunger can be removed by un-screwing the small cap at
the very top of the tube. That way you could remove it and see what you are
doing. I have never taken one apart and am not willing to start this
