1、冷(leng)熱水(shui)管(guan)(guan)(guan)(guan)主要(yao)是以PPR水(shui)管(guan)(guan)(guan)(guan)為主，既(ji)可作冷(leng)水(shui)管(guan)(guan)(guan)(guan)也(ye)可作熱水(shui)管(guan)(guan)(guan)(guan)，無毒耐壓耐腐蝕。冷(leng)水(shui)管(guan)(guan)(guan)(guan)一般外面會有藍色標記(ji)的(de)(de)直線，熱水(shui)管(guan)(guan)(guan)(guan)則是外面有紅色線標記(ji)的(de)(de)管(guan)(guan)(guan)(guan)材(cai)，材(cai)料及價(jia)格(ge)會有些微區(qu)分，不要(yao)弄錯了。

2、飲用水(shui)(shui)管(guan)(guan)需(xu)不結垢不生銹、具有(you)環保安全抗(kang)菌性，因此一般以PE管(guan)(guan)、PPR管(guan)(guan)為主。PE給水(shui)(shui)管(guan)(guan)一般只做(zuo)冷水(shui)(shui)管(guan)(guan)，而(er)PPR管(guan)(guan)可做(zuo)冷熱(re)水(shui)(shui)管(guan)(guan)。在裝(zhuang)修中可兩種(zhong)管(guan)(guan)材搭配使(shi)用。

3、家用排(pai)水(shui)管道、下水(shui)管對管道材(cai)質的要求不是(shi)很高，通常是(shi)以UPVC排(pai)水(shui)管為主，其耐(nai)化(hua)學腐蝕(shi)，抗沖強度高，耐(nai)老化(hua)，使用壽命長(chang)，使用年限不低于50年，是(shi)建筑給排(pai)水(shui)的理(li)想材(cai)料。

4、電(dian)路(lu)是家(jia)裝裝修中的(de)重要(yao)環節，暗線(xian)(xian)在(zai)墻內(nei)，明線(xian)(xian)則在(zai)墻上。由(you)于家(jia)裝電(dian)路(lu)眾多，可用電(dian)線(xian)(xian)管，可以保護線(xian)(xian)纜，方(fang)便(bian)今后的(de)維(wei)護，一般(ban)選(xuan)用PVC線(xian)(xian)管，絕緣(yuan)性(xing)能好、阻燃防(fang)火、耐熱抗(kang)壓。

5、地(di)(di)暖(nuan)(nuan)(nuan)管(guan)(guan)(guan)分(fen)水(shui)地(di)(di)暖(nuan)(nuan)(nuan)和(he)電(dian)(dian)(dian)(dian)(dian)地(di)(di)暖(nuan)(nuan)(nuan)，水(shui)地(di)(di)暖(nuan)(nuan)(nuan)，是(shi)以(yi)溫度不高于60℃的熱水(shui)埋于地(di)(di)下填充層中(zhong)的加(jia)(jia)熱管(guan)(guan)(guan)內循環流動，惻(ce)然加(jia)(jia)熱整個(ge)地(di)(di)板；而電(dian)(dian)(dian)(dian)(dian)地(di)(di)暖(nuan)(nuan)(nuan)是(shi)將外表面允許工作溫度上限(xian)為65℃的發熱電(dian)(dian)(dian)(dian)(dian)纜(lan)埋設(she)在地(di)(di)板中(zhong)，以(yi)發熱電(dian)(dian)(dian)(dian)(dian)纜(lan)為熱源加(jia)(jia)熱地(di)(di)板。通常(chang)比較常(chang)見的水(shui)地(di)(di)暖(nuan)(nuan)(nuan)管(guan)(guan)(guan)以(yi)PERT管(guan)(guan)(guan)材為主，而電(dian)(dian)(dian)(dian)(dian)地(di)(di)暖(nuan)(nuan)(nuan)則采用發熱電(dian)(dian)(dian)(dian)(dian)纜(lan)。
