1、冷(leng)熱(re)水(shui)(shui)(shui)(shui)管(guan)主要(yao)是以PPR水(shui)(shui)(shui)(shui)管(guan)為主，既(ji)可作冷(leng)水(shui)(shui)(shui)(shui)管(guan)也(ye)可作熱(re)水(shui)(shui)(shui)(shui)管(guan)，無(wu)毒(du)耐(nai)(nai)壓(ya)耐(nai)(nai)腐蝕(shi)。冷(leng)水(shui)(shui)(shui)(shui)管(guan)一(yi)般(ban)外(wai)面(mian)會有藍色標(biao)記的(de)直線，熱(re)水(shui)(shui)(shui)(shui)管(guan)則是外(wai)面(mian)有紅色線標(biao)記的(de)管(guan)材(cai)，材(cai)料及價格(ge)會有些微區分，不要(yao)弄錯了。

2、飲用水管(guan)(guan)需不結垢不生銹、具(ju)有環保(bao)安全抗(kang)菌性，因(yin)此一(yi)般(ban)(ban)以PE管(guan)(guan)、PPR管(guan)(guan)為主。PE給水管(guan)(guan)一(yi)般(ban)(ban)只做冷水管(guan)(guan)，而PPR管(guan)(guan)可做冷熱(re)水管(guan)(guan)。在裝修中可兩種管(guan)(guan)材搭配(pei)使(shi)用。

3、家用(yong)(yong)排(pai)水(shui)管(guan)(guan)(guan)道(dao)、下(xia)水(shui)管(guan)(guan)(guan)對管(guan)(guan)(guan)道(dao)材(cai)質的要(yao)求不(bu)是(shi)(shi)很高，通常是(shi)(shi)以(yi)UPVC排(pai)水(shui)管(guan)(guan)(guan)為主(zhu)，其(qi)耐化(hua)學腐蝕，抗沖強度(du)高，耐老化(hua)，使(shi)用(yong)(yong)壽命長，使(shi)用(yong)(yong)年限(xian)不(bu)低(di)于(yu)50年，是(shi)(shi)建筑給排(pai)水(shui)的理想材(cai)料。

4、電(dian)路是家裝(zhuang)裝(zhuang)修中(zhong)的(de)重要環節，暗線(xian)(xian)(xian)在墻(qiang)內，明線(xian)(xian)(xian)則(ze)在墻(qiang)上。由于家裝(zhuang)電(dian)路眾多，可用(yong)電(dian)線(xian)(xian)(xian)管，可以保護(hu)線(xian)(xian)(xian)纜，方便今(jin)后的(de)維(wei)護(hu)，一般選用(yong)PVC線(xian)(xian)(xian)管，絕緣性能好、阻燃防火、耐熱抗壓。

5、地(di)(di)(di)(di)暖(nuan)(nuan)管(guan)(guan)分水(shui)(shui)地(di)(di)(di)(di)暖(nuan)(nuan)和電地(di)(di)(di)(di)暖(nuan)(nuan)，水(shui)(shui)地(di)(di)(di)(di)暖(nuan)(nuan)，是(shi)以溫度不高于60℃的熱(re)水(shui)(shui)埋于地(di)(di)(di)(di)下填充層中(zhong)(zhong)的加熱(re)管(guan)(guan)內循(xun)環流(liu)動，惻(ce)然(ran)加熱(re)整個地(di)(di)(di)(di)板；而電地(di)(di)(di)(di)暖(nuan)(nuan)是(shi)將(jiang)外表面允許工作溫度上限為(wei)65℃的發熱(re)電纜(lan)埋設在地(di)(di)(di)(di)板中(zhong)(zhong)，以發熱(re)電纜(lan)為(wei)熱(re)源加熱(re)地(di)(di)(di)(di)板。通常比較常見的水(shui)(shui)地(di)(di)(di)(di)暖(nuan)(nuan)管(guan)(guan)以PERT管(guan)(guan)材為(wei)主，而電地(di)(di)(di)(di)暖(nuan)(nuan)則(ze)采(cai)用發熱(re)電纜(lan)。
