Toilet drainage is an important part of bathroom renovation. We use large amounts of water every day for toilets and baths. Therefore, the quality and scientific nature of the toilet drain installation must be high. Otherwise, it will bring great trouble to our lives. Next Xiao Bian to introduce toilet drainage pipe installation precautions.
First, the use of bathroom pipe installation tools
Toilet drains, pvc tubes, adhesives, inspection openings, expansion joints
Second, the toilet water pipe installation correct order
Before the installation of the water pipe in the bathroom, certain reasonable steps must be followed. Generally, it is necessary to discuss with the installation master the specific direction of the waterway. The second step is to use the electric hammer to fix the clamp to the wall. The third step is to start using a professional hot melt machine. The tube is hot-melted. The fourth step is to test the entire pipeline with a pressure test pump. The fifth step is to clean the site.
Third, the bathroom plumbing design layout
The installation of the bathroom pipes should be laid according to the direction of the water, generally horizontal and vertical. As far as possible, the two pipes do not cross. If the bridge is crossed, the hot and cold water pipes should be separated and maintain a certain distance, and the right and left positions of the shower valve should be correct. And installed in the middle of the bathtub, the best height of 1.8 meters to 2.1 meters, but also for the installation of water heaters and washing machine inlet and outlet set aside, so that a scientific and rational layout.
Fourth, bathroom plumbing installation pressure measurement process
Before the pressure test, the water meter should be closed, the pressure at the end of the pressure test pipe should be plugged and slowly filled. After the water is filled, it should be sealed and checked. Then, the pressure should be manually increased. After the pressure is stabilized, the pressure drop within half an hour shall not exceed 0.05 Mpa. .
Fifth, toilet pipe installation precautions
First of all, material aspects. Drainage pipe is usually made of PVC pipe. The high-level drain pipe is best used with double-walled hollow or spiral noise reduction. The adhesive and water pipe concealment project must use the best material. Must be done without odor and watertight, with the best flame retardant properties. Drainage cross pipe should have a slope, generally not less than 1%; pay attention to the drainage slope when installing the drainage pipe is conducive to timely discharge of sewage.
Followed by a drainage cross pipe with more than 1 sanitary ware, you need to increase the cleaning mouth (examination port). The checkpoint is generally one meter off the ground, and the center of the h-tube is about one meter five. The inspection port is used for inspection and quick troubleshooting.
In addition, if the length of the PVC riser exceeds 4 meters, a telescopic joint is added. The telescopic section is based on the center of the three links and is generally about forty-three or twenty-three. More than two meters across the pipe to increase expansion joints.
At the same time, if the sanitary ware itself does not have a trap, be sure to install S-type or P-type traps on the pipeline to prevent odors from escaping from inside the pipeline to ensure fresh air in the toilet.
In addition, high-level risers must also block fire circles and install pipelines away from sources of fire to avoid accidents.
Editor's summary: The decoration of the bathroom is generally the same as our other rooms, but due to the special nature of its function, we need to strengthen it in some aspects. The special function of the bathroom gives it high demands in terms of waterproofness, odour prevention, ventilation and anti-slip.
