which many thanks -..it seems very likely that the issue is caused by the pump

<P class=MsoNormal><SPAN style="mso-fareast-language: en-us">Despite what you
guys suspect by now(!), I study form religiously before I delve into these
things and have been brought up short by a section in the BMC manual, Section
G8, “Pump Valve”. One is told how to put the “pump body” back in using one of
many mythical special tools and then the manual addresses the insertion of the
“plunger” (piston):- “The pump plunger is prevented from rotation when in
position by a guide peg carried in the front casing. When assembling the pump,
the plunger should be inserted with the flat on its head facing the rear of the
unit. It is possible to guide it past the guide peg by means of a screwdriver
inserted through the side of the casting”.<o:p></o:p></SPAN></P>
