There is information present on each overflow trap ranging in importance from the part number and serial
number to numbers stamped on the tank. This information is important for identifying the overflow trap,
installing it correctly, and obtaining parts. An example of the current factory serial number label used on
313 overflow traps is shown here. The accompanying table identifies the information present and where to
find it on the overflow trap. There may also be other numbers and marks present that do not provide useful
information. Customer specific tagging may also present. The labels or plates used, and information present,
on Warren Controls other product lines or older overflow traps may be different, contact the factory for details.
