When using home decoration PPR pipes in home decoration, strict waterproof measures should be taken when passing through the house. A fixed support frame shall be installed at the front end of the passing pipe to avoid deformation of the pipe, loosening between the passing pipe and the casing and leakage. When the home decoration PPR pipe transmitting hot water passes through the wall, it should be equipped with steel casing made of earth to facilitate the free extension of the pipe transmitting hot water.
When the home decoration PPR pipe passes through the wall, a hole can be prepared first. The size of the hole is 50mm larger than the outer diameter. For the pipes directly buried in the ground plane layer and the wall, the pressure test and acceptance records of concealed works must be made before the plugging of the wall to ensure the installation quality of the project. In our country, when the toilet is decorated, there is no wall hole specially made for the drainage horizontal branch pipe of PPR pipeline. Therefore, the pulling and connecting parts of plastic pipe and faucet at the water distribution point are not embedded in the wall, but are laid on the outside of the wall.
For the accessories of the fire hydrant embedded in the brick wall, in addition to stabilizing it outside the brick wall, it should also use high-standard cement slurry or Epoxy Mastic to stably embed it in the wall. How to fix this piece with the brick wall is the main thing. If the end of the branch pipe is a faucet, install an elbow according to the general practice. However, in order to be stable with the wall, it is changed into a three-way piece, but one of these pieces will not be connected. Connect the shorter pipe of zinc plated steel pipe at the end that will not be connected, smash the end of the tail, plunge it into the wall, and fill it with cement slurry.
