Use grooved mechanical couplings and fasteners only in accessible locations.

Install unions downstream of valves and at equipment or apparatus connections.

Install brass male adapters each side of valves in copper piped system. Sweat solder adapters to pipe.

Install [gate] [ball] [or] [butterfly] valves for shut-off and to isolate equipment, part of systems, or vertical risers.

Install [globe] [ball] [or] [butterfly] valves for throttling, bypass, or manual flow control services.

Provide spring loaded check valves on discharge of water pumps.

Provide plug valves in [Natural] [propane] gas systems for shut-off service.

Provide flow controls in water recirculating systems where indicated.

ERECTION TOLERANCES

Establish invert elevations, slopes for drainage to [1/4] [1/8] [_____] inch per foot ([2] [one] [_____] percent) minimum. Maintain gradients.

Slope water piping and arrange to drain at low points.

DISINFECTION OF DOMESTIC WATER PIPING SYSTEM

Prior to starting work, verify system is complete, flushed and clean.

Ensure PH of water to be treated is between 7.4 and 7.6 by adding alkali (caustic soda or soda ash) or acid (hydrochloric).

Inject disinfectant, free chlorine in liquid, powder, tablet or gas form, throughout system to obtain 50 to 80 mg/L residual.

Bleed water from outlets to ensure distribution and test for disinfectant residual at minimum 15 percent of outlets.

Maintain disinfectant in system for 24 hours.

If final disinfectant residual tests less than 25 mg/L, repeat treatment.

Flush disinfectant from system until residual equal to that of incoming water or 1.0 mg/L.

Take samples no sooner than 24 hours after flushing, from [10] [5] [2] percent of outlets and from water entry, and analyze in accordance with AWWA C651.

SERVICE CONNECTIONS

Provide new [sanitary] [storm] sewer services. Before commencing work check invert elevations required for sewer connections, confirm inverts and ensure that these can be properly connected with slope for drainage and cover to avoid freezing.

Provide new water service complete with [[reduced pressure] [double check] backflow preventer and] water meter with by-pass valves [pressure reducing valve,] [and sand strainer].

Provide sleeve in wall for service main and support at wall with reinforced concrete bridge. Calk enlarged sleeve and make watertight with pliable material. Anchor service main inside to concrete wall.

****** [OR] ******

Provide 18 gage (1.20 mm) galvanized sheet metal sleeve around service main to 6 inch (150 mm) above floor and 6 feet (1800 mm) minimum below grade. Size for minimum of 2 inches (50 mm) of loose batt insulation stuffing.

Provide new gas service [complete with gas meter and regulators]. Gas service distribution piping to have initial minimum pressure of [_____] inch wg ([_____] kPa). [Provide regulators on each line serving gravity type appliances, sized in accordance with equipment.
