First, the use of toilet water pipe installation tools
Toilet drain pipe, pvc pipe, adhesive, inspection port, expansion joint
Second, the correct order of toilet water pipe installation
Before installing water pipes in the bathroom, we must follow certain reasonable steps. Generally, it is necessary to discuss the specific direction of the waterway with the installation master first. Step 2, fix the clip on the wall with an electric hammer. Step 3, start the hot-melt connection of the pipeline with a professional hot-melt machine. Step 4, use the pressure test pump to suppress the whole pipeline. Step five, clean up the scene.
Third, the design and layout of toilet water pipe installation
Bathroom water pipes should be laid according to the direction of water flow, generally horizontal and vertical, and the two pipes should not cross as much as possible. If they cross the bridge, the hot and cold water pipes should be separated to keep a certain distance. The left and right positions of the mixing valve of the bathtub should be correct, and it should be installed in the middle of the bathtub, with the height between 1.8 m and 2. 1 m, and the installation positions of the inlet and outlet of the water heater and washing machine should be reserved to make the layout scientific and reasonable.
Four, toilet water pipe installation pressure measurement process
Before pressure test, close the valve behind the water meter, plug the pressure test pipe end, slowly fill it with water, then check the seal, and then manually boost the pressure. After the pressure is stabilized, the pressure drop within half an hour is less than 0.05Mpa.
Five, toilet water pipe installation matters needing attention
First of all, in terms of materials. Generally, PVC pipes are used for drainage pipes, and double-wall hollow or spiral noise reduction is best for high-rise drainage pipes; Adhesives and concealed works of water pipes must use the best materials. It must be odorless, waterproof and have the best flame retardant properties. The horizontal drainage pipe should have a slope, generally not less than 65438 0%; Pay attention to the drainage slope when installing the drainage pipe, which is conducive to the timely discharge of sewage.
Secondly, if a horizontal drainage pipe has more than 1 sanitary ware, it is necessary to add cleaning ports (inspection ports). The inspection port is generally one meter from the ground, and the center of H tube is about one and a half meters. The inspection port is used for maintenance and quick troubleshooting.
In addition, if the length of PVC riser exceeds 4m, expansion joints should be added. The expansion joint is based on the tee center, generally about 43, and the short pipe is 23. Expansion joints should be added to horizontal pipes over two meters.
At the same time, if the sanitary ware itself does not have a trap, it is necessary to install an S-shaped or P-shaped trap on the pipeline to prevent the pipeline from overflowing odor and ensure the fresh air in the bathroom.
In addition, the high-rise riser should be provided with a fire ring, and the installed pipeline should be far away from the fire source to avoid accidents.
The above contents are the matters needing attention in the renovation of drainage pipes introduced for everyone today. We know that the decoration of the bathroom is basically the same as that of our other rooms, but because of its special function, it needs to be strengthened in some aspects to be foolproof. The special function of toilet endows it with high requirements in waterproof, deodorizing, ventilation and anti-skid. These are exactly what we need to pay attention to in the process of decorating the drainage pipe. Now do you understand how important this is?
