一、PPR管怕长时间太阳照射，所以安装时可适当用泡沫保温套套住，最好用3.4厚的热水管，这样更经久耐用。二、先把线路弄好，再地上开槽，我觉得应该让水电工做比较好，由于至少人家专业吧，万一自己接的水管漏水就不大好了。三、从PPR管的连接来说是：热熔连接的。热熔温度为260度。从您的安装尺度那就要参考您的设计尺度了。这个得根据您的家装设计了。一般PPR不能走明装，第一明装PPR要受重力变形，第二明装PPR轻易老化。第三假如是白色的PPR，明装轻易透光形成滋生细菌。所以都是建议暗埋。四、PPR水管也可以使用热熔承插的连接方法，管材和管件完全融为一体，接头的强度甚至超过了管材本体的强度，只要施工得当，完成后通过打压测试，可靠性极高。

不是你的 06-26 09:13

由于PPR管的热涨系数与水泥的热涨系数不同，实际使用时PPR管一直处于受拉压的状态，所以设计标准要求不得在铺设的地面下有PPR管的对接接头。如果不可避免要对接，则对接接头处要有足够长度的PPR管“悬空”，不被埋铺在水泥里，且两段管要尽可能大角度对接，不得直通对接

不是你的 06-26 09:21

你好，ppr管埋地敷在地面上是可以设接头的，但是这个接头需要设计的合理，选择合适的位置，而且一定要用东西包裹好，这样使用的时候不至于损坏。希望我的回答可以帮到你。
