CEME Pressurestat

[Bombcup]

I've ballsed up a CEME pressurestat; tried to adjust it down but nothing was happening. First thought was that the adjuster screw had let go of the diaphragm, I removed the unit and the screw dropped straight out. Fffffuuuuu....

The cheapo POS doesn't want to let me in to repair it. Is it just a chuckaway or has anyone managed to mend one?

[P.B]

I didn't bother to even try. I replaced the one in my Andreja with a Mater XP110 (I mistakenly thought the CEME one had failed). The Mater is less "touchy" to adjust and has a smaller dead-band. However, it only lasted about 2.5 years so maybe pressure stats are best regarded as consumables...
