Unfortunately, the PRV is totally inaccessible, buried beneath a rats-nest of Whale quick-connect fittings. I initially thought there was no alternative to biting the bullet and removing the calorifier. But then I thought I'd try a bit of lateral thinking and I accessed the leak-off pipe from the faulty PRV, cut into it and fitted a new PRV inline. Works perfectly and saved me a lot of hassle.
