1、冷(leng)熱(re)水(shui)(shui)(shui)管(guan)(guan)主要是以PPR水(shui)(shui)(shui)管(guan)(guan)為主，既可作冷(leng)水(shui)(shui)(shui)管(guan)(guan)也可作熱(re)水(shui)(shui)(shui)管(guan)(guan)，無(wu)毒耐(nai)壓(ya)耐(nai)腐蝕(shi)。冷(leng)水(shui)(shui)(shui)管(guan)(guan)一(yi)般(ban)外面會有藍色(se)標(biao)記的(de)直線，熱(re)水(shui)(shui)(shui)管(guan)(guan)則(ze)是外面有紅色(se)線標(biao)記的(de)管(guan)(guan)材，材料(liao)及價格會有些微區(qu)分(fen)，不要弄錯了。

2、飲用(yong)水管(guan)需不(bu)(bu)結垢不(bu)(bu)生(sheng)銹、具有環(huan)保(bao)安全(quan)抗菌性，因(yin)此一般(ban)以PE管(guan)、PPR管(guan)為主。PE給水管(guan)一般(ban)只(zhi)做冷(leng)水管(guan)，而PPR管(guan)可(ke)(ke)做冷(leng)熱(re)水管(guan)。在裝(zhuang)修中可(ke)(ke)兩種管(guan)材搭配使用(yong)。

3、家(jia)用(yong)排(pai)水(shui)(shui)管(guan)道、下水(shui)(shui)管(guan)對管(guan)道材(cai)質的要(yao)求不(bu)是(shi)很(hen)高(gao)(gao)，通常是(shi)以UPVC排(pai)水(shui)(shui)管(guan)為主，其(qi)耐化學腐蝕，抗(kang)沖強度高(gao)(gao)，耐老化，使(shi)用(yong)壽命(ming)長，使(shi)用(yong)年限不(bu)低于50年，是(shi)建筑給排(pai)水(shui)(shui)的理想材(cai)料。

4、電(dian)路是(shi)家裝(zhuang)裝(zhuang)修中的重要環(huan)節，暗線(xian)在(zai)墻(qiang)內，明線(xian)則在(zai)墻(qiang)上(shang)。由于家裝(zhuang)電(dian)路眾多，可(ke)用電(dian)線(xian)管，可(ke)以保護線(xian)纜(lan)，方便今后的維護，一(yi)般(ban)選用PVC線(xian)管，絕緣(yuan)性能好(hao)、阻燃防火(huo)、耐熱抗壓(ya)。

5、地(di)(di)(di)暖管(guan)(guan)分水(shui)(shui)地(di)(di)(di)暖和電(dian)(dian)地(di)(di)(di)暖，水(shui)(shui)地(di)(di)(di)暖，是以溫度不高于60℃的(de)熱(re)(re)水(shui)(shui)埋于地(di)(di)(di)下填充層(ceng)中的(de)加熱(re)(re)管(guan)(guan)內(nei)循(xun)環流動(dong)，惻然加熱(re)(re)整個地(di)(di)(di)板(ban)；而電(dian)(dian)地(di)(di)(di)暖是將外表面允許工(gong)作(zuo)溫度上限為(wei)65℃的(de)發熱(re)(re)電(dian)(dian)纜埋設(she)在地(di)(di)(di)板(ban)中，以發熱(re)(re)電(dian)(dian)纜為(wei)熱(re)(re)源加熱(re)(re)地(di)(di)(di)板(ban)。通常比較常見(jian)的(de)水(shui)(shui)地(di)(di)(di)暖管(guan)(guan)以PERT管(guan)(guan)材(cai)為(wei)主，而電(dian)(dian)地(di)(di)(di)暖則采用發熱(re)(re)電(dian)(dian)纜。
