Nice video. I use tile file or cleaning strips and it works a treat. Also 1 one pound coin is 3mm not 2. Very useful video.

[@DALEYPLUMBING]

Great video John

[@k956upg]

£1 coins stuck together isn't 3mm it's over 6mm the best gap is 4 mm in my experience so just over £1 coin size.

[@6804harry]

Brilliant videos John... Do you do the Ravenheat boiler training ? Coming up to Leeds on 29/9...

[@ijazhussain7127]

Great effort. Thank you very much for such an informative video. CAN YOU PLEASE MAKE ONE FOR FLUE ANALYSER TEST AND FLUE INTEGRITY TEST please
