As an apprentice my old fitter told me about his sprinkler system. Back in the early days Gasfitters used candles to work in cellars and lofts I kid you not! He was working in the loft and knocked the candle over it rolled and fell down into an internal lath and plaster cavity. He looked down and the blinking candle was still alight 10 feet down at the base of the cavity wall ! He hadn't the time to get water so he got his built in hose out and peed on it to put it out He said he wondered if the people were looking around for the source of any strange smells after a few days
If you wish to be offensive JP at least get your spelling right. There are a few of us here that live in Wales and some who are Welsh. Kind regards BS
