How to install the bathroom drain pipe yourself

Be sure to do a good job of drainage. 1. The water pipe is a hidden project, and the size of the water pipe must be considered more comprehensively when arranging the size of the water pipe, or it is not easy to use in the later stage, and it is more troublesome to maintain. Toilet drain pipe size: The inner diameter of the sewer pipe is 100mm to 3000mm, and the length is 30mm to 200mm.

2. DN50 is used in the toilet as long as it is not a toilet, and DN100 is used for the toilet and the pipeline after the toilet. Sewer pipes, kitchen and bathroom sewage and wastewater can not be discharged together, kitchen sink with DN50, floor drain with DN50, together with DN75. The drain connected to the toilet bowl should be DN110.

The unique double corrugated structure effectively improves the external pressure strength of the product, and the drainage system will not be affected by the external pressure deformation. The choice of bathroom drain pipe size must not be sloppy, you must know that there is no reasonable design, and the water discharged from the water pipe will flow slowly when we use it, so it is very inconvenient to use, so it is very important to choose the size of the bathroom drain pipe.

Bathroom drainage is an important part of bathroom decoration, and the frequency of daily use is high, therefore, the quality and scientificity of bathroom drainage pipe installation must be high. Otherwise, it will bring a lot of trouble to our lives.

Clean the area around the reserved drain nozzle, remove the temporary pipe plug, and check whether there is any debris in the pipe. Find the centerline of the drain mouth and draw it on the wall. Use a level (or sinker) to find a good vertical line.

Smear putty on the sewer socket, lay white plaster under the squatting toilet, and then put the squatting toilet drain into the drain pipe socket to stabilize it. At the same time, use a level to put it on the upper edge of the squatting toilet, and level and align it vertically and horizontally. Align the squatting toilet inlet with the centerline on the wall.

At the same time, the two sides of the squatting toilet are plastered with bricks, and the putty at the contact between the drainage port of the squatting toilet and the socket of the drainage pipe is compacted and wiped. Finally, seal the drain of the squatting toilet with a temporary plug. When installing a multi-connected squatting toilet, you should first check whether the elevation of the drainage pipe mouth and the size of the flick mouth from the wall are consistent.

Find out the standard ground elevation, measure the height required by the squatting toilet upward, level it with a small line, find the distance between the walls, and then stabilize the installation one by one according to the above methods.

High water tank stabilization: It should be carried out after the squatting toilet is stabilized. First of all, check whether the center of the squatting toilet is consistent with the center line of the wall, and if there is any dislocation, it should be adjusted in time, so that the squatting toilet is not twisted.

Determine the position of the center line of the water outlet of the water tank, and measure the specified height upwards (the water supply outlet is 2m away from the step surface). At the same time, combined with the distance between the fixed hole of the high water tank and the water supply hole, find out the height position of the fixing bolt, draw a cross line on the wall, cut it into a 30*100mm deep hole, flush the debris in the hole with water, and insert the dovetail bolt into the hole and twist it with cement. Hang the high water tank with the fittings on the fixing bolts, add rubber pads, eye circles, and nuts and tighten them until they are properly tightened.

After the sanitary ware and equipment are installed, a water test must be carried out. And it should be carried out before the final process of painting.
