Decoration is how to install water pipes.

(1): In home decoration, it is best not to walk on the ground, because the water pipes are installed on the ground, which will bear the pressure of tiles and people, and there is a danger of cracking the water pipes. In addition, the advantage of taking the roof is convenient maintenance. The salary is very high, and most people don't need it.

(2): The slotting depth of water pipes, the ash layer after cold water burial is greater than 1cm, and the ash layer after hot water burial is greater than 1cm.

(3): Hot and cold water pipes should follow the principle of hot water on the left and cold water on the right.

(4): PPR hot-melt pipes are generally used for water supply pipelines, which has the advantages of good sealing performance and fast construction speed. However, workers must be reminded not to rush. If the force is not correct, the pipeline may be blocked and the water flow will be reduced. If this happens to the toilet flush valve hose, the bedpan will not be cleaned.

(5): After water pipes are laid, they should be fixed with pipe clamps first, and then sealed. Cold water pipe clamp spacing is not more than 60 cm, hot water pipe clamp spacing is not more than 25 cm.

(6): Horizontal pipe clamp spacing, with cold water pipe clamp spacing not more than 60 cm and hot water pipe clamp spacing not more than 25 cm.

(7): The installed hot and cold water pipe heads should be at the same level. Only in this way can the installation of hot and cold water switches be beautiful.

(8): After the water pipe is installed, plug the pipe head immediately. If sundries fall in, it will be in trouble!

(9): After the water pipe installation is completed, pressure test must be carried out! Check the installed water pipe for water seepage and water leakage, and seal the groove after pressure test.

(10): During the pressing test, the press pressure must reach above 0.6, and wait for more than 20-30 minutes. If the pointer position of the pressure gauge has not changed, the installed water pipe is sealed, so the sealing groove is safe.

(1 1): Although there is no pressure in the sewer pipe, it is necessary to check the drainage, and carefully check whether there is water leakage or seepage.
