Show lO DETECT LEAK IN GAS PIPE. Lather of Soap Much Better Than . Using a Match. r Tho folly of hunting for a leak In a gas plpo with a lighted match Is not .ii.-fMi'"'1' oeca"s3 of tho danger of nn explosion as of other damage, as Is shown by tho experience of a West Philadelphia householder Inst week. One or two small leaks were detected by going over all tho pipes and holding hold-ing n lighted match to them. The Btnell of gas ceased, but was replaced ft fow hours later by tho smell of burning wood. Another -visit to the cellar showed a charred floor Joist a llttlo dlstanco abovo a gas pipe. Thero was no apparent cause for this until ft very close examination discovered that a tiny Jet of gas was Issuing from tho plpo beneath tho beam. It was lighted, hut was so small as to be bluo In color and nearly Invisible. It had been lighted by tho match used In the first Investigation, but had not been noticed. "if that leak had happened to bo In a lead Joint Instead of an Iron connection," con-nection," said a gas man, "thero would probably hao been work for tho flro department. The smallest possible Jet of lighted gas Issuing through lend will In tlmo heat and molt tho lead and mako tho leak larger, larg-er, until a big flamo Is Issuing. This may make a flro hours later, In tho dead of night or at a tlmo when no one Is In the house. Tho only proper prop-er way to look for theso vory small leaks Is to paint tho suspected plpo with n smooth soap lnther. Just as In tho caso of a blcjclo tire, tho tiniest tini-est leak will blow a bubble In tho SfcgiTr, an'' thero ou are." Phlladel- -JW-no |
