Hi all, I`ve only just found this site, and it looks as if it will be of great help, to me & anyone else. Going over this old problem, our push button cistern is also slow to fill, I hope my picture, if it is there will help the cleverer! People out there than me, with advice as to how to fix it, if its worth the trouble, or replacing the thing. Any advice greatly appreciated, cheers.

Your attachment didn't make it. Here's directions,

How do I add pictures and other file types to my post?
A. "Attach" files (including pictures) from your computer. This method puts the attached file below the text of the post.
Click on an Ask or Answer button to ask or answer a question
Compose your question or answer in the window.
Under the window where you composed your question or answer is a section called Additional Options.
Click on the Manage Attachments button: a pop-up dialog will open. NOTE: The Manage Attachments dialog lists the maximum sizes of the various types of files that may be attached.
Click the Browse button to navigate to the image on your computer and double click the file on your computer: this will return you to the dialog window.
Click the Upload button.
Click the link to close the dialog window OR repeat numbers 5 & 6 to attach another image.
B. "Embed" image(s) from the internet. This method inserts an image wherever you wish within the text of your post.
Click the Insert Image icon above the posting window: A pop-up asking for the URL will open.
Enter the URL of the image in the field then click the OK button.

Now for that slow filling cistern. Tell me what ballcock that's in there?
Back to you, Tom
