PVC给水管是用来做给水用的，也有部分用于农田灌溉，与排水管最大的区别就是需要能承受压力，如果是给水工程上还需要有卫生指标，无毒无污染等检测指标。目前PVC给水管的市场份额在缩小，被质量性能更为优越的PE管材所取代。排水管道应在施工前对原有管道临时封口，避免杂物进入管道。管道排列应符合设计要求，管道安装应固定牢固，无松动，龙头、阀门安装平整，开启灵活，出水畅通，水表运转正常。

一、满足最佳水力条件1．给水管道布置应力求短而直。2．为充分利用室外给水管网中的水压，给水引入管宣布设在用水量最大处或不允许间断供水处。3．室内给水干管宜靠近用水量最大处或不允许间断供水处。
二、满足维修及美观要求1．管道应尽量沿墙、梁、柱直线敷设。2．对美观要求较高的建筑物，给水管道可在管槽、管井、管沟及吊顶内暗设。3．为便于检修，管井应每层设检修门。暗设在顶棚或管槽内的管道，在阀门处应留有检修门。4．室内管道安装位置应有足够的空间以利拆换附件。5．给水引入管应有不小于0．003的坡度坡向室外给水管网或坡向阀门井、水表井，以便检修时排放存水。

隐蔽的给水管道应经通水检查，新装的给水管道必须进行加压试验，应无渗漏。
2、排水管道应在施工前对原有管道临时封口，避免杂物进入管道。
3、管外径在25mm以下给水管的安装，管道在转角、水表、水龙头或角阀及管道终端的100mm处应设管卡，管卡安装必须牢固。
4、所有接头、阀门与管道连接处应严密，不得有渗漏现象，管道有坡度。
5、水管安装不得靠近电源，水管与燃气管的间距应不小于50mm。
6、进水管全部用热水PPR管，下水管用PVC管。冷热水管应左热右冷。
