家庭装修水管尺寸有哪些？

一般家用水管规格有：DN15(4分管)、DN20(6分管)、DN25(1寸管)、DN32(1寸2管)、DN40(1寸半管)、DN50(2寸管)、DN65(2寸半管)、DN80(3寸管)、DN100(4寸管)、DN125(5寸管)、DN150(6寸管)、DN200(8寸管)、DN250(10寸管)等。

水管Φ25×1/2的意思它的外径是25。实际对应的公称直径是DN20(也就是人们常说的6分管)。你可以去买6分的水龙头。也可以去买4分的水龙头(只要在管子和水龙头之间加一个变径就可以了)。

PPR管有20、25、32、40、50、63、75、90、110、160(单位：mm)十种规格，一般家装有20、25、32三种规格就足够了。S3.2和S2.5热水管，这两种是家庭用的热水管道，有PPR标准型和PPR抗菌型的，是用于暖气的话就用标准型PPR就可以了。S4和S5为冷热水管。大家一般用4分管的(管径25mm，厚度在3.4mm)样子，一般都用热水管的，PPR管分C管、B管的之分，主要是与工作温度有关！

家装先ppr品牌是比较倾向于进口的品牌，虽然贵一点点，但管道千万不能贪图便宜，要讲求性价比，家里要是出现爆管漏水，重新翻修也很麻烦的。还要注意ppr水管的材质，保证饮水健康。
一般情况下，如果家里不是别墅，4分水管就足够，只有家里是别墅，有几个卫生间，或者住在楼房的高层，有可能水压小，这时才需要考虑是不是用6分管。
像们家一般先说冷水，从墙面出来的内丝弯头都是20的，也就是说，各种龙头的出水口是20的，用25的管径目的是在多点同时分流用水时，水流不变小。用20管，明显在多点用水时，出水会比25小的。
