Win YOU kindly let me know some

lions in the gasoline pipes. from leak leak
ing2 No matter how tight these may
be, the gasoline seems to leak through.
&C. H s.
The ground beveI joints in the con-
nectfOus must be buried or otherwise
impaired to permit such leaks II
not this, then the connections are i'm
properly sOldered on the ends Of the
pipe line The nut at these points
should. when tight. make these joints
Eas tight Very often in making these
connections ordinary washing soap or
gum arabic is used to prevent slight
leaks. If the connections are prop
erly fitted, however, neither Of these
substances should be necessary Would
suggest that you inspect the gas line
thoroughly for any crack OF slight
opening at the points where the con-
necCiOns are made.
