I have replaced my Camray boiler/Riello burner flex hoses regularly without difficulty but this year have run into a problem with the 1/4 inch BSP connections into the burner oil pump using newly purchased hoses.
Basically the design of this year's manufacture of 'Bio Green' flex hose is such that I can only get one turn of the right angle male nipple into the oil pump female thread before the joint 'bottoms'. To my mind this is quite unacceptable and I have ended up refitting the old 'Bio Green' hoses which had at least two threads of engagement. Earlier designs of hose I recall having four plus threads of engagement (much more sensible), and the basic nipple itself (of whatever period) has about eight threads available.
I am going to raise this with manufacturer soon but would welcome the comments of others first. Is my experience a unique one? Has the basic design been changed for a reason? How should I proceed?
