Mine , is running a lit cigarette lighter around valve/along pipework a diy safety check ?,I ve always done that ,valve is fitted tight as tight expected ,hose and end clips renewed on 2 year cycle ,cannot come up wiv a "at home" alternative,?do the bottle valves have a "blow back" system fitted/built in, does anyone know?Ta
i use some water with washing up liquid in it , brushed on to the joints with a paint brush , itf there is a leak it will bubble up all over the place ...
i'm gessing there isn't a great deal of pressure but unless there is some kind of blow back arrestor in the line/bottle then it's a bit mad...... i used my nose to check mine the other day when i fitted new hose maybe i'll check properly with fairy and water.
