The installation of sanitary ware is also the finishing work of hard-packing. In the early stage, the sanitary ware was selected. When the hard-loading is finished, the sanitary ware installation is not simple. Although it is very small, there are many details, such as the installation of the toilet. Do a good job of drainage and a series of measures, then the following small series will introduce you to the sanitary ware installation knowledge and some installation specifications to help the decoration owners to decorate smoothly.
Basic knowledge of sanitary ware installation
(1) Sanitary ware installation and construction process
Sanitary ware inlaid wall tiles → suspended ceiling → laying floor tiles → installing toilets, washbasins, bathtubs → installation and connection to drain pipes → installation of lamps, sockets, mirrors → installation of towel bars and other hardware accessories.
1. Toilet process
Check the ground drain pipe → align the nozzle → level the alignment → draw the mark → punch the hole → apply the putty → set the rubber pad → screw the nut, → mark the two holes on the back of the tank, → punch → Insert the bolt → æ» â†’ → Back to the tank to find the right direction → Screw on the nut → Install the back water tank elbow → Install the splayed door → Turn the maiden fork to the right → Insert the drift door and the splayed door → tighten the nut.
2. The process of the washbasin
Insert the expansion bolts → æ» â†’ → the tube rack is hung up → put the washbasin on the rack to find the level → water connection: washbasin → straighten → water connection.
3. Bathtub process
Bathtub installation: → water installation → putty closed tight → water installation → flattening
4. Shower process
Cold and hot water nozzles are flattened with test tubes → measure the size of the short section → install on the nozzle → wash the copper inlet of the shower with lead oil, wrap → nut tighten → fix on the wall → upper copper tube is installed in the three-port → The wood screws are fixed to the wall.
5. The process of the bidet
The door cover and nut of the mixing switch and the hot and cold water door are leveled, → the water gate is installed → the nozzle core door is installed → the hot and cold water door outlet nut is tightened → the nut of the mixing switch is tightened → three water door covers are installed → the magnetic basin is installed Good → When installing the nozzle → Install the water outlet → When installing the portable lever → Adjust the positioning.
(2) Essentials for installation and construction of sanitary ware
1. Installation and installation essentials for sanitary ware washing basin:
(1) The washing basin product should be flat and non-destructive. The drain plug should have an overflow hole of not less than 8 mm in diameter.
(2) When the drain plug and the sink are connected, the overflow plug of the drain plug should be aligned with the overflow hole of the sink to ensure the smooth flow of the overflow. After the insert, the upper end of the drain plug should be lower than the bottom of the wash basin.
(3) The bracket fixing bolts can be galvanized bolts or galvanized metal expansion bolts of not less than 6mm (if the wall is porous brick, expansion bolts are strictly prohibited).
(4) After the washing basin is connected with the drain pipe, it should be firm and compact, and easy to disassemble. The joint should not be open. Silicone paste caulking is applied to the wash basin and wall contact.
(5) If the wash basin drain trap and faucet are plating products, the plating shall not be damaged during installation.
2, the installation of sanitary ware tub:
(1) When installing the skirting tub, the bottom of the skirt should be close to the ground. The floor should be reserved for 250~300mm holes in the drainage area to facilitate drainage installation. The inspection hole is installed in the wall of the bathtub drainage end.
(2) Other types of bathtubs can determine the height of the upper surface of the bathtub according to relevant standards or user requirements. Then install the tub after laying two brick foundations. For example, if the side wall of the bathtub is built, the inspection hole should be set at the drain of the bathtub or the inspection hole should be opened on the wall of the drainage end.
(3) The height of all kinds of bathtub cold, hot water taps or mixing faucets should be higher than the plane above the bathtub 150mm, and the chrome plating layer should not be damaged during installation. The chrome cover should be in close contact with the wall.
(4) The height of the fixed shower and hose shower can be installed according to relevant standards or according to user requirements.
(5) The upper surface of the bathtub installation must be leveled with a horizontal ruler and must not be inclined. Apply a sealing paste to the side of the upper side of the bathtub and the wall.
(6) The connection between the bathtub drain and the drain pipe should be firm and compact, and it is easy to disassemble, and the joint should not be open.
3, the installation points of sanitary ware toilet
(1) The installation angle of the water supply pipe is generally 250mm from the ground to the center of the angle valve. If the installation of the one-piece toilet should be based on the height of the water inlet of the toilet, but not less than 100mm, the center of the angle valve of the water supply pipe is generally sewage. 150mm to the left of the tube center or according to the actual size of the toilet.
(2) Low water tank toilet The water tank is fixed with galvanized bolts or with galvanized metal expansion bolts. If the wall is porous brick, it is strictly forbidden to use expansion bolts. Soft gaskets should be used between the water tank and the nut. It is strictly forbidden to use metal hard surface.
(3) With a water tank and a one-piece toilet, the back of the water tank should be no more than 20mm from the wall.
(4) The installation of the toilet is not less than 6mm galvanized expansion bolts, and the soft gasket is fixed between the toilet and the nut. The sewage pipe should be exposed to the ground 10mm.
(5) When installing the toilet, first apply the putty around the bottom drain, then align the toilet outlet to the sewage pipe and slowly press it down to compact it, then tighten the gasket nut to remove the squeeze. Put out the putty, and clean it with a wire or a rag immediately after filling it with the putty around the base.
(6) The height of the overflow pipe in the flush tank should be 30~40mm below the wrench hole to prevent the water from overflowing from the wrench hole when the inlet valve is damaged.
(3) Sanitary ware installation precautions
1. Do not damage the waterproof layer. If it has been damaged or has no waterproof layer, it must be waterproofed first and tested by water leakage for 12 hours.
(2) The sanitary ware is fixed firmly and the pipe interface is tight.
(3) Pay attention to the protection of finished products to prevent bumps and sanitary ware.
