Question 1

what are the dimensions of this item

Accepted Answer

All of these are pretty standard in size. This is made so that it will fit at least two different sizes. The way it came, it didn't fit, but I used scissors as instructed to cut one little piece off of it, and it fit perfectly, snapped right into place and worked like a dream. The whole thing (including going and finding a pair of scissors) took less than 5 minutes. That includes reading the instructions, too. Unless your toilet was made in another country, I'd guess there's a 99% chance that this will either fit perfectly as-is, or with a small cut with scissors, will fit perfectly. Pay attention to where the chain from the lever is fastened so you can fasten it back in the same place.

Question 2

Has anybody used this flapper successfully in modern (1.6 gpf) toilets, or will it only work in old 3.5 gpf toilets?

Accepted Answer

You could try it in a 1.6 GPF toilet...But it works best for 3.5 GPF toilets made before 1994. Fluidmaster  labels it as being a universal flapper. That's all I know about it. Other than it has a 5 year warranty.

Question 3

I release the toilet lever it goes straight to the bottom which means that the tank doesn't fully empty.  Its predecessor floated.  What's wrong?

Accepted Answer

Some flapper just do this.. I just hold the toilet flushing handle down a few minutes to be sure it is fully empty.

Question 4

The fluidmaster 504 is the form I need because the toilet is old and does not have mounting ears but is it made out of rubber or plastic?
