From indoor to outdoor check well the drainage pipe, well within the introduction of pipe should be higher than the discharge or two top tube is flat, and there are not less than 90 degrees of flow Angle, such as poor fell more than 300 mm is not restricted by Angle. (10) equipped with hidden or buried pipes, must be done before the hidden water test, the water height should be not less than the height of the underlying. 2, sanitary ware installation When installing sanitary ware (11), not because of the construction and the intensity of the structure of the building, should not be due to the use of sanitary equipment construction quality decline. (12) if some pipes must be through the structure of the column, beam and aseismic walls, and other important components, should be reserved perforation position in civil engineering design and construction phase. Decoration construction not casual knock when the chisel structures. (13) in the chisel cut operation, it is prohibited to use hammer percussion, lest cause the vibration of the whole structure caused by the separation of steel and concrete. (14) shall ensure that the horizontal and vertical installation, and grassroots anchor safe and solid. 3, lavatory installation (1) along the basin along the mouth should be placed on mesa, skull basin along the mouth should be close to the end of mesa. Mesa height in general are 800 mm. (2) the basin is made of steel mesa component bracket, detection of mesa structure before install lavatory sinks the beam height, install lavatory pelvic floor can add rubber gasket leveling, skull basin should limit fixed. (3) a joint along the lavatory and mesa, anointed with seal seam, shall not be leakage around the mouth. 4, wash basin water supply accessories installation (1) the match type faucet installation 1) long neck the faucets directly on dry feed water pipe threaded pipe fittings, ordinary faucet available external thread spools and the coupling connection. 2) single cold water faucet located in the center line of the basin wall, above the basin along the 200 mm (1000 mm) above the ground. 3) the cold, hot water tap center distance 150. Ming pipe installation, the hot water faucet is higher than the cold water tap 100 mm (1100 mm) above the ground. 4) dark pipe installation, cold and hot water faucet flush, cold water horizontal tube is 925 mm high, hot water supply high horizontal tube is 1075 mm. 5) fitted with type lavatory faucet, water tap hole using magnetic cap on the wall. (2) the match type feed Angle width of installation 1) the Angle valve installation height of 450 mm, high horizontal pipe 350 mm cold water, hot water horizontal pipe installation must be between 525 mm high diagonal vertical metope, Angle valve position and lavatory faucet hole position on a vertical line. 2) metope reserved feed pipe mouth position slightly higher deviation, Angle valve and the connection between the faucet copper tube can be bent into a curved, b word but Angle valve with metope nozzle must be positive. 3) the Angle valve with metope between nozzle connection pipe, with galvanized welded steel pipe connection, external thread on both ends of the connecting pipe, one end of the installation Angle valve, the other end of the screw thread into the wall pipe fittings. 4) use galvanized copper pipe connection, has galvanized copper tube end and Angle valve welding as a body, the other end of the feed pipe mouth flat metope place for inside and outside of inner grooved tubes or nipple, copper pipe position flax hoop (or aprons) and packing gland, and after chrome plated brass insert pipe joint, into the flax hoop, mix on gland, make the pipe gap seal, no leakage. 5) use a metal hose connection Angle valves and taps, fill in the aprons inside the lock nut, lock nut and make joint without leakage. 6) metope to take over the connection of the roots and cover with decorative cover, should be clingy metope adornment cover. (3) the match type bright piping installation 1) horizontal pipe installation height is 250 mm cold water, hot water horizontal branch height is 350 mm, the branch pipe connected to the lavatory faucet, 450 mm high cut-off valve installation. 2) bright piping required horizontal tube good levelness, connect the faucet with a vertical riser requirements for good. (4) the lavatory drainage accessories installation 1) the lavatory drain plug, the installation of trap. 2) type P trap outlet height is 400 mm, and wall body have a drain connection. 3) S type of trap outlet connected to the ground the reserved drainpipe, reserved drainpipe center is 70 mm from the wall. 4) reserved drainpipe, wall, ground is DN32 external thread tube, wall, ground 20 mm higher trap pipe inserted into the drain outlet (insert depth of about 40 mm), after the gland nut and tighten with aprons on pipes, exterior decorative cap, wall, ground. 5) under the lavatory drain plug is not install trap lavatory, drain installation. A, cross drainage tube is 450 mm high, diameter should not less than (, and should be a drain minimum slope. B, drainage tube head should install tee and plug. C, trap outlet connected to the wall, ground nozzle roots without decoration cover.
