Have a TRUMA c3400 stripped down for a rebuild. inside coating and totally delaminated but after a clean and paint that will be sorted. It may need a replacement gas solenoid and i wonder if a Gas solenoid valve for C 4002 and C6002 will fit. It looks identical in photos and can be got in 50mbar form.If not does anyone have the gas solenoid from a C3400 from a boiler that has bit the dust. For interest sake i will include some photos to show the pitting that 20 years use can create. The lining almost came out in one piece which may have happened years ago and probably did.
