Hello all... Can anyone advise me on how to remove the large tapering red knob on the PRV? I spoke with a Baxi employee who told me that the red kno b could be removed easily to reveal the seal and seating which may need a c lean... I cannot fathom any way of removing it! It is quite loose until a bout 1/3 of a turn anticlockwise when it appears to engage the spring mecha nism... We are loosing pressure over a few days. Any help would be grea tly appreciated...
