Section 1 - Domestic Water Systems
(CSI - Div. 15, Section 15-E Water Supply Systems) GRINNELL Mechanical Grooved Pipe couplings, fittings and butterfly valves as manufactured or supplied by GRINNELL Mechanical Products shall be used for all water supply systems under operating conditions not to exceed 110°C (230°F) temperature. The coupling gasket and encapsulated disc on butterfly valves shall be Grade “E” EPDM.
1.1 Materials:
1.1.1 Pipe - Pipe shall be galvanised steel pipe, conforming to ASTM A-135, A-795 or A-53. All pipe shall be prepared according to GRINNELL published specifications, or to ANSI/AWWA C-606 grooved end pipe. Pipe ends shall be prepared as detailed in Basic Materials and Methods and to the latest GRINNELL published specifications.
1.1.2 Couplings - All GRINNELL grooved couplings and fittings shall be painted or galvanised Figure 705, 707, 772 or 716 with Grade “E” EPDM gaskets and zinc plated bolts and nuts.
1.1.3 Branch Connections - Shall be made with Figure 730 and/or Figure 522.
1.1.4 Flange Connections - Flange connections shall be GRINNELL Figure 71 Flanges incorporating Grade “E” EPDM gasket.
1.1.5 Fittings - Fittings shall be painted or galvanised GRINNELL standard ductile iron or segmentally welded steel fittings, with grooved ends.
1.1.6 Butterfly Valves - Shall be of grooved end design with a Grade “E” EPDM encapsulated disc. Upper stem shall be stainless steel. Valves shall have pressure assisted double seal and be capable of 300 psi, bubble-tight-shutoff. Butterfly valves
shall be with gear actuator or hand lever. Operating conditions not to exceed -34°C to 110°C (-30°F to 230°F).
1.1.7 Check Valves - Shall be of grooved end design with a clapper seal of Grade “E” EPDM. Valves shall be capable of pressures of 300 psi. The valves shall have a spring loaded clapper to ensure a leak tight seal and a nonsticking operation. The clapper seat in the valve body shall be nickel. Operating conditions not to exceed -34°C to 110°C (-30°F to 230°F).
Section 2 - Storm Drains / Roof Drains
GRINNELL mechanical grooved pipe couplings and fittings as manufactured by GRINNELL Mechanical Products shall be used for all storm and roof drainage systems.
2.1 Materials:
2.1.1 Pipe - Pipe shall be galvanised steel pipe, conforming to ASTM A-135, A-795 or A-53. All pipe shall be prepared according to GRINNELL published specifications, or to ANSI/AWWA grooved end pipe. Pipe ends shall be prepared as detailed in Basic Materials and Methods and to the latest GRINNELL published specifications.
2.1.2 Couplings - Couplings shall be galvanised Figure 705, 707, 772 or 716 with Grade “E” EPDM gaskets and zinc plated bolts and nuts.
2.1.3 Flange Connections - Flange connections shall be galvanised GRINNELL Figure 71 Flanges incorporating Grade “E” EPDM gasket.
