WATERLINE CROSSINGS REQUIRE THAT THE DRINKING WATER OR WASTEWATER PIPE BE
ENCASED FOR AT LEAST TEN (10) FEET OF EACH SIDE OF THE CROSSING OR PLACE
WHERE COMPONENTS ARE CLOSER THAN TEN (10) FEET. PIPE OF SCHEDULE 40
RATING OR BETTER MUST BE USED, OF SUFFICIENT DIAMETER TO EASILY SLIDE OVER
AND COMPLETELY ENCASE THE LINE. RIGID END CAPS OF A7 LEAST SCHEDULE 40
RATING MUST BE GLUED OR SECURED IN A WATERTIGHT FASHION TO THE ENDS OF
THE ENCASEMENT PIPE. THERE MUST BE A HOLE OF SUFFICIENT SIZE TO
ACCOMMODATE THE PIPE IN THE LOWERMOST SECTION OF THE RIGID CAP SO THAT
THE CONVEYANCE PIPE RESTS ON THE BOTTOM OF THE ENCASEMENT PIPE. THE
AREA IN WHICH THE PIPE PASSES THROUGH THE ENDCAPS MUST BE SEALED WITH AN
APPROVED UNDERGROUND SEALANT COMPATIBLE WITH THE PIPING USED.
