2. Installation of water supply pipe

First, it is  necessary to check the quality of the materials and keep them in stock. There are two types of pipes commonly used in Vietnam: PVC pipes and PPR pipes. Of these two types of pipes, PVC pipes are cheaper, simply installed with specialized glue. As for the PPR, the pipe, the installation will be somewhat more complicated because you have to use a cutting machine and a welding machine.

The water supply pipe must be installed so that it sinks into the wall is the toilet area. To ensure this, when installing, it is necessary to cut chisels to create grooves on the wall. The average cutting depth is form 3 to 4 cm and the width falls form 5 to 10 cm depending on the installation location.

After the pipe is installed, cement mortar will be used to fix the pipe on the wall and on the floor.

The civil water supply vertical shaft is designed by ≤ D63 diameter PPR pipe. For correct installation, you should base on the drawing to determine the correct location. Using pipe racks to make the shaft pipes stand, the distance between the supports is 1.6m. After the water pipes are installed vertically, the supports must be stable. you determine to place the water pump and pour  concrete on the pump base so that when operating there is no vibration.

When the work as plastering. The finished paving and ceiling is when you can install the toilet. Use synchronous gaskets to connect equipment with water pipes.
