Anyone familiar with these? One of mine wouldn't seal at the weekend and on taking it apart the diaphragm is missing and is presumably rattling around inside the tube somewhere. The plastic spindle doesn't appear to be broken although the thread is a bit dodgy. From the
tiny parts pics I have been able to find on the web the diaphram seems to have an integral threaded brass (?) centre but what stops it unscrewing itself in use?
I'll probably buy the spares kit (might even go daft and get three and replace them all) but was just wondering.
OTOH the idea of retrieving the diaphragm and screwing it all together again without disturbing the moths in my wallet is also appealing.
