1、冷(leng)熱(re)水(shui)(shui)管(guan)(guan)(guan)主要是(shi)以PPR水(shui)(shui)管(guan)(guan)(guan)為(wei)主，既可(ke)作冷(leng)水(shui)(shui)管(guan)(guan)(guan)也(ye)可(ke)作熱(re)水(shui)(shui)管(guan)(guan)(guan)，無毒耐壓耐腐蝕。冷(leng)水(shui)(shui)管(guan)(guan)(guan)一般外(wai)面會(hui)有(you)藍色標(biao)記(ji)的直線，熱(re)水(shui)(shui)管(guan)(guan)(guan)則是(shi)外(wai)面有(you)紅色線標(biao)記(ji)的管(guan)(guan)(guan)材(cai)，材(cai)料及價(jia)格會(hui)有(you)些微區(qu)分(fen)，不要弄錯(cuo)了。

2、飲用水管(guan)需(xu)不(bu)結垢(gou)不(bu)生(sheng)銹、具有環(huan)保安(an)全(quan)抗菌性，因此一(yi)般(ban)以PE管(guan)、PPR管(guan)為(wei)主。PE給水管(guan)一(yi)般(ban)只做冷水管(guan)，而(er)PPR管(guan)可做冷熱水管(guan)。在(zai)裝(zhuang)修中可兩種管(guan)材搭配使用。

3、家用排(pai)水(shui)管(guan)(guan)道、下水(shui)管(guan)(guan)對管(guan)(guan)道材質的要求不(bu)是很(hen)高(gao)，通常是以UPVC排(pai)水(shui)管(guan)(guan)為主，其耐化學腐蝕(shi)，抗沖強(qiang)度高(gao)，耐老化，使用壽命(ming)長，使用年限不(bu)低于50年，是建(jian)筑給排(pai)水(shui)的理想材料。

4、電(dian)路是家裝裝修(xiu)中的重(zhong)要(yao)環節(jie)，暗(an)線(xian)(xian)在墻內(nei)，明線(xian)(xian)則在墻上。由于家裝電(dian)路眾(zhong)多，可用(yong)電(dian)線(xian)(xian)管(guan)，可以(yi)保護(hu)線(xian)(xian)纜，方便(bian)今后的維護(hu)，一般選用(yong)PVC線(xian)(xian)管(guan)，絕緣(yuan)性能好、阻燃防(fang)火、耐熱(re)抗壓。

5、地(di)(di)(di)(di)暖(nuan)管(guan)(guan)分(fen)水地(di)(di)(di)(di)暖(nuan)和電(dian)(dian)(dian)地(di)(di)(di)(di)暖(nuan)，水地(di)(di)(di)(di)暖(nuan)，是(shi)以(yi)溫度不高于(yu)60℃的(de)熱水埋于(yu)地(di)(di)(di)(di)下(xia)填充層中的(de)加(jia)(jia)熱管(guan)(guan)內循環流(liu)動，惻然加(jia)(jia)熱整個(ge)地(di)(di)(di)(di)板；而電(dian)(dian)(dian)地(di)(di)(di)(di)暖(nuan)是(shi)將外表面允許(xu)工作溫度上(shang)限為(wei)65℃的(de)發(fa)熱電(dian)(dian)(dian)纜埋設在地(di)(di)(di)(di)板中，以(yi)發(fa)熱電(dian)(dian)(dian)纜為(wei)熱源(yuan)加(jia)(jia)熱地(di)(di)(di)(di)板。通常(chang)比較常(chang)見的(de)水地(di)(di)(di)(di)暖(nuan)管(guan)(guan)以(yi)PERT管(guan)(guan)材為(wei)主，而電(dian)(dian)(dian)地(di)(di)(di)(di)暖(nuan)則采(cai)用發(fa)熱電(dian)(dian)(dian)纜。
