lame plumber
having just seen another arguement between a proffessional and a diyer on an oil boiler, wouldnt it be better for us just refer to the forum name ie UKPlumbers forum which serves proffessionals in the trade and those with questions not involving safety issues. Or better still set up a oil section for qualified folk in the same manner as the gas side, then life would be so much better for all concerned, no arguements as croppie will kill the thread
