Show TO DETECT LEAK IN GAS PIPE. H Lather of Soap Much Better Than Using a Match. IR Tho folly of hunting for a leak In a H gas pipe with a Jtshted match Is not H so much because of tho danger of no H explosion ns of other damage, as Is H shown by the expcrlenco ot a West H Philadelphia householder Inst week. H Ono or two smnll leaks wero detected H by going over all the pipes and hold- fling fl-ing a lighted match to them. The H smell ot gas ceased, but was replaced 6 1 a ' tow hours Inter by the smell of burning wood. Another visit to the cellar showed a charred floor Joist a little dlstnnco above a gns pipe. There was no apparent cause for this until ' a very closo examination discovered' H that a tiny Jet of gas was Issuing H from tho plpo bencnth tho beam. It H was lighted, but was bo small as to be H blue In color and nearly Invisible It I had been lighted by tho match usod I In tho first investigation, but had not' been noticed. I "It that leak hnd happened to be I In a lend Joint Instead ot an Iron con- I nectlon," said a gas man, "thore I would probably have been work for I ' tho ilro department. Tho smallest I posslblo Jet of lighted gas Issuing' I through lead will In timo heat and I melt tho lead and mako tho leak larger, larg-er, until a big flame is Issuing. Thla " may make a fire hours Inter, In tho dead of night or at a tlmo when no ono is in tho house. The only proper prop-er way to look tor theso very small leaks Is to paint tho suspected pipe with a smooth soap lather. Just as In tho caso ot a blcyclo tiro, tho tiniest tini-est leak will blow a bubblo in the lather, and thero you nre." Phlladel- A . phla Record. |
