I had the same problem, but have (so far) found it impossible to get the pressurestat off. As a consequence, my PV has been languishing under the stairs. Having found a wrench low profile enough to get to the back of the pressurestat at its mounting point, my main fear has been shearing off what seems to be a (mostly) brass screw thread holding it all together. Am I being too gentle? Should I be getting out a hammer and giving the spanner a bit of "encouragement"?
