Hiltan:
The problem was that all of the links were too long to fit on one line on this web site. So, the web site computer would truncate the links. The problem was that when anyone else would click on that truncated link, their computer would interpret the dots where the truncation occured as the actual web site address, and not be able to find the correct link.

So, I found away around that problem. If you go to a previous page on this forum, you should find a thread entitled "How a toilet ballcock works". That thread will give the following instructions which SHOULD get you to the right PDF file:
__________________________________________________ _______________

So, what you're saying is that the truncated link, with the three dots in it's URL is being interpreted by other people's computers as being the full URL of the link?

OK, then let's do it this way:

Use any web browser to search for web pages containing the phrase

Water hammer in toilet tank

In the resulting list, find the "kirsner" web page which starts as follows:

http://www.kirsner.org/pages/Toile****erhammer.html

(without the asterisks)

It should be near the top of the list.

Near the middle of that web page there will be a link in a red font which reads:

http://support.fluidmaster.com/reald...alve_works.pdf

(without the dots)

Click on that link.

That link will take you to the correct Fluidmaster web page that explains how their diaphragm opens and closes due to the same water supply pressure acting on different size areas on each side of the diaphragm.

Post again if you don't get to the right web page.
