做排水管时注意坡度：尤其是空调冷凝排水管，ppr管品牌，如果管子比较长，施工质量不好容易妨碍排水，导致返水至冷凝水盘漏水。解决办法：按照设计图纸标示的坡度，定好点，ppr管价格，放好线，按照相应的间距，下料做好吊支架。
Pay attention to the slope when making the drainage pipe: especially the air conditioning condensate drainage pipe，马鞍山ppr管， if the pipe is relatively long and the quality is not good， it is easy to hinder the drainage， resulting in the leakage of return water to the condensate pan. Solution: according to the slope marked on the design drawings， set a good point， set a good line， according to the corresponding spacing， do a good job of lifting support.
冷热水管
PPR水管分为热水管和冷水管，会有蓝色、红色线标识。冷水管管壁较薄，热水管管壁较厚，更加耐用些，加上冷热水管价差不大，所以，现在大部分家庭，装修都会考虑全屋热水管，冷水也使用热水管。
Cold and hot water pipePPR water pipe is divided into hot water pipe and cold water pipe， which will be marked with blue and red lines. The wall of cold water pipe is thinner， and the wall of hot water pipe is thicker， which is more durable. In addition，ppr管规格， the price difference between cold and hot water pipes is not big. Therefore， most families now cider the whole house hot water pipe for decoration， and cold water also uses hot water pipe.
管道固定后才能使用中，管材不会因为水压而造成共振现象的发生。PPR水管在固定式，要使用管卡固定，对于管材间距在500mm左右，外径在25mm以下的管道，其在管道的终端10厘米处及水表处等地亦要设置管卡。
PPR pipe fixing
The pipe can not be used until it is fixed. The pipe will not cause resonance due to water pressure. PPR water pipe is fixed with pipe clamp. For pipes with pipe spacing of 500mm and outer diameter less than 25mm， pipe clamps shall be set at the end of pipeline at 10 cm and water meter.
