    Never seen this weird problem before. A friends two year old WC valve silicone washers have blisters so bad that the cisterns leak all the time

    The washers seem to have expanded a few mm in diameter and .3mm in thickness, see pics , what in water could cause silicone to blister yet not be harmful to us?

    See below for link to photo

    Sorry, what type of picture is it? Dropbox won't show it because it doesn't have an extension and file says it is "ISO Media" whatever that is and gimp says it can't open it.

    No different from when I tried it the first time.

    However notwithstanding the picture could the problem be with the washer material rather than the water

    It's a jpeg so any image viewer should be able to open it. But the file name is a bit weird: 'siliconr\ washers\ ii'. i.e. there's a carriage return and a space in the filename and no extension, so some noddy operating systems might have problems. Which begs the question of why Tony can't use some normal name, like 'image.jpg', and why he can't just attach it to the message in the normal way.

    And yes, I suspect something was wrong when the washers were made.

    I have a lot of troubles with photos and can’t add them to my posts.

    Having looked at the pics I'd say definitely poor quality washer material. How about buying a small amount of silicone sheet or similar and cutting your own. I'd guess food or medical grade would be the best.

    I can't view photo either. However no prizes for guessing where such poor performing washers were made.

    Something that was sprayed on them when they were fitted?

    Not much touches silicone in my experience - must be some kind of manufacturing fault.

    The easiest way I find is to view the photo on the screen (laptop or desktop) then use the "snipping tool" or "snip & sketch" which allows you to drag a box from a corner over the image to select some or all of it. Then save this to the desktop (with an easy to find name) so that you can attach it to your GBF post.
    Because it is effectively a screen grab, the quality is lower and so the file is smaller, usually small enough to upload to the GBF.

    Tip: avoid saving screenshots as JPEG/JPG. The compression algorithm it uses is designed for photos where you get gradual transitions from one colour to another. JPG makes a mess of harsh changes like text (words look like they have clouds of flies around them)

    If it's a screenshot of a photo, crack on, but otherwise use PNG or GIF

    That’s interesting, I didn’t know that.
