PLASTIC SADDLE TEE OR WYE FITTING.
(SOLVENT WELD)
ADJUSTABLE STAINLESS STEEL
STRAPS AND SCREWS.
WHEN A CONNECTION TO A PLASTIC PIPE IS ALLOWED AND A CONNECTION IS LARGER THAN 6" IN DIAMETER,
A SOLVENT WELD WYE OR TEE FITTING OF A SIMILAR MATERIAL MUST BE USED. (EXAMPLE: 10" X 8")
THIS IS ACCOMPLISHED BY CAREFULLY CUTTING A HOLE WITH A SAW IN THE MAIN AT THE REQUIRED LOCATION.
AFTER CUTTING AND SHAPING THE HOLE TO THE SIZE OF THE FITTING, THE FOLLOWING STEPS SHOULD BE TAKEN:
NOTES:
1) CLEAN AND DRY BOTH INSIDE SADDLE WYE SURFACE AND PIPE SURFACE TO BE SOLVENT CEMENTED.
2) IMPORTANT: APPLY A LIBERAL, HEAVY COAT OF ONE-STEP SOLVENT CEMENT TO THE INSIDE
SURFACE OF THE SADDLE WYE AND TO THE EXTERIOR WELDING SURFACE TO THE PIPE.
3) WITHOUT DELAY, MATE THE SURFACES AND STRAP DOWN TIGHTLY. A BEAD OF SOLVENT SHOULD APPEAR
AFTER THE SADDLE HAS BEEN STRAPPED DOWN TIGHTLY.
4) USING A RAG OR PAPER TOWEL, WIPE BEAD AND ANY EXCESS SOLVENT CEMENT OFF PIPE AND SADDLE.
5) ALLOW 30-60 MINUTES FOR SET-UP TIME BEFORE BACKFILLING. CURE TIME DEPENDS ON SIZE AND FIT
OF MATERIALS BEING INSTALLED AND VARIOUS COLD DAMP CONDITIONS.
6) DISCARD OLD SOLVENT IF IT BECOMES JELLED OR LUMPY.
7) A CLEAN, DRY BEDDING MATERIAL IS REQUIRED AROUND THE COMPLETED CONNECTION BEFORE BACKFILLING.
THE BEDDING MATERIAL SHOULD BE ONE OF THE FOLLOWING:
A) M.S.D. NO. 1 BEDDING.
B) 1 TO 3 CEMENT TO SAND MORTAR MIX.
C) "PRE -MIX" CONCRETE.
