Funso: A Tim, nthawi zonse ndikazimitsa mpope m’nyumba mwanga, paipi yamadzi imamveka phokoso lalikulu kwambiri. Malingaliro anga, iwo akhoza kusweka. Vutoli ndi lofala m’nyumba zambiri za m’khwalala langa, chifukwa ndafunsa aneba anga ngati ali ndi vuto lomweli. chinachitika ndi chiyani? Kodi womanga kapena plumber analakwitsa poyika chitoliro? Kodi pali chiopsezo cha kuphulika kwa mapaipi ndi kusefukira? Kodi pali njira yosavuta, kapena DIY? Thandizani musanafunikire jekete lamoyo! —Pam H. Clearfield, Pennsylvania
Yankho: Ndili ndi zaka za m’ma 20, ndinamva chiphokoso chachikulu chochititsidwa ndi nyundo yamadzi m’nyumba zoyamba zimene ndinkakhala. Ndimakhala kudera lomwe madzi akumatauni amakhala pafupi ndi 80 pounds per square inch (PSI). Kuthamanga kwamadzi kwakukulu ndikwabwino kwa ma shawa ndi mapaipi a m'munda, koma phokoso limakhala lovuta, makamaka pamene ma valve a makina ochapira amagetsi ndi otsuka mbale atsekedwa.
Mukachotsa zolemba zamasukulu a sekondale, mupeza chifukwa chake nyundo yamadzi imachitika. Choyamba, madzi ndi amadzimadzi, ndipo zamadzimadzi zambiri sizingafanane. Madziwo ndi olemera. Imani kwa kamphindi ndikuganiza za liwiro lomwe madzi amathamangira kunja kwa payipi yamunda. Nthawi zambiri, awa ndi liwiro lomwe madzi amayendera mupaipi yanu yamadzi.
Tangoganizani ngati madzi apaipi angokhala kagawo kakang'ono ka sitima yonyamula katundu ikulira. Mwadzidzidzi, kutsogolo kwa locomotive, valve inatsekedwa. Sitimayo inagunda valavu, ndipo mphamvu inachititsa kuti mafunde amphamvu kwambiri adutse paipiyo. Kuthamanga kwakukulu mu dongosolo kumatha kupitirira 180 PSI. Mukubetchera kuti pakapita nthawi, izi zitha kuyambitsa mavuto. Mafunde osawerengeka ogwedezeka angapangitse kutayikira koopsa.
Okonza mapaipi omwe amaika mapaipi amatha kuteteza nyundo yamadzi poika mapaipi okulirapo m'kati mwake. Kwenikweni, mapaipi akuluakulu amachepetsa liwiro la madzi oyenda mupaipi. Zomwe amayenera kuchita ndikukulitsa mapaipi amadzi ¾-inchi ku gulu lililonse lokonzekera ndi zida zazikulu, monga makina ochapira ndi zotsukira mbale. Makinawa ali ndi ma valve amagetsi omwe amatseka madzi ngati sakufunika.
Njira yoperekera mapaipi a PEX ingathandizenso. Njira zosinthira, zatsopano zoperekera madzi am'mipopi zimayikidwa zofanana kwambiri ndi zingwe. Zikhoza kugwedezeka ndi kusuntha kuti zitenge mafunde odzidzimutsa, omwe ali ngati mabomba omwe akuphulika mumtsinje wa madzi. Monga mukudziwira, mkuwa ndi wolimba ndipo ukhoza kugunda ndi kunjenjemera.
Nkhani yabwino ndiyakuti mutha kuyimitsa nyundo yamadzi mnyumba mwanu m'njira zambiri. Ngati muli ndi luso lopaka mapaipi apakati, ndiye kuti ndi mwayi wa DIY kuti muchotse miyuni yowotcherera ndi zida zina.
Ndiyamba kukhazikitsa zinthu ziwiri: valve yochepetsera kuthamanga kwa masika ndi matanki amodzi kapena awiri okulirapo. Zida zonsezi zamtengo wapatali zimatha kusintha mahatchi akutchire akuthamanga mumtsinje.
Valavu yochepetsera kuthamanga imatha kusinthidwa potembenuza screw. Onetsetsani kuti mumvetsere momwe madzi amayendera pa thupi la valve. Nthawi zambiri, imayikidwa pambuyo pa valavu yayikulu yotseka m'nyumba mwanu. Mukathira madzi, chonde ikani valavu yayikulu yotsekera mpira, ngati valavu yanu yachipata ndi yakale. Ma valve a mpira amatha kuyenda bwino ndipo nthawi zambiri amakhala opanda vuto kwa zaka zambiri.
Mukayika valavu yatsopano ya mpira, ganizirani kukhazikitsa cholumikizira chanjira zitatu kuti chiziyika mu chitoliro chopopera kuti madzi onse mupaipi athe kukhetsedwa mosavuta. Ma plumbers ambiri sangathe kukhazikitsa chowonjezera chosavuta ichi. Ndikhazikitsanso cholumikizira chachiwiri munjira yayikulu yoperekera madzi. Izi zikuthandizani kuti muyike choyezera kuthamanga kwa madzi. Ndikhulupirireni, simudzanong'oneza bondo kukhala ndi mmodzi wa iwo.
Mukayika zigawo zonse, ganizirani kukhazikitsa thanki yowonjezera ya galoni itatu. Izi ndi zida zazikulu, muli chikhodzodzo cha rabara mu thanki yamadzi. Thumba la mpweya limalekanitsa madzi mu dongosolo kuchokera ku thovu la mpweya mu thanki yamadzi. Onetsetsani kuti mwayika tanki yamadzi kuti malo olowera alowe pansi. Izi zimasunga thovu pamwamba pa madzi m'malo mokhala pansi pake.
Ma thovu a mpweya amakhala ngati zoziziritsa kukhosi m'magalimoto kapena m'magalimoto, chifukwa mpweya umakhala wopindika. Matanki okulitsawa amagwiranso ntchito ziwiri, kuteteza chotenthetsera chanu chamadzi chosungira, chifukwa madzi otentha amafunikiranso malo oti akule.
Ndikudziwa kuti iyi ingawoneke ngati ntchito yovuta, koma sichoncho. Ngati mukudziwa zomwe mukuchita, mutha kumaliza ntchito zonsezi mu ola limodzi kapena kuchepera. Ingotsatirani malamulo a mipope ndi machitidwe abwino, ndipo nyumba yanu posachedwapa idzakhala chete ngati mwanawankhosa.
