Question 1

why is there an occassional sound from the dual flush system?

Accepted Answer

Not sure what's making the noise but check my tips in case the noise is from a slow leak that might suggest needing to replace another part besides the flusher:See my review, ( http://www.amazon.com/HYR270-HydroRight-Drop-Flush-Converter/product-reviews/B002NKRR7Y/ref=cm_cr_pr_btm_link_next_4?ie=UTF8&pageNumber=4&showViewpoints=0&sortBy=bySubmissionDateDescending ) "Works great; but some toilets might need their Fill Valve also. Read my tips., November 26, 2013" and also my response to a negative reviewer, "Roc1 says:  Readers, you should take this reviewer's disparaging remarks about the quality of the blue dome gasket with a grain of salt. ..." of Dec 3, 2013 7:35:34 AM PST".

Question 2

Tank does not fill while toilet keeps running continuously. Blue gasket seal looks just fine. What am I doing wrong?

Accepted Answer

Reposition the assembly over the fill tube valve seat and use the neoprene washer on the fill tube to hold it place. Check out you tube video on how to install.

Question 3

how high does the assembly stand above the tank floor?

Accepted Answer

I have installed 3 of these, and will not go back to the old flapper flush valve.  I measured one of mine, and it stands just over 11 inches from the bottom of the tank, about an inch or so lower than my existing fill valve.  Installation is extremely simple, and I have installed in tanks with both front and side flush handle sitings.

Question 4

Will this work with tanks that doesn't have overflow tube?

Accepted Answer

No, if there is no overflow tube, it can't be mounted or at least without engineering some way to secure it. The whole device would float.
