Dhizaini, kushanda nesimba uye kusimba kwematembiricha-kutonga mayunitsi (TCUs) akavandudza maitiro ekutonga muindasitiri yemapurasitiki kubvira zvakatanga kushandiswa muma1960s.Nekuti maTCU anowanzo kuvimbika uye anoshanda zvakasiyana, anowanzo famba-famba kwakawanda uye akabatanidzwa kune akasiyana matsime emvura uye akasiyana mold uye michina yekugadzira.Nekuda kwekuvapo uku kwechinguvana, iyo nhamba-yekutanga yekunetsekana kweTCUs inowanzobatanidza kuvuza.
Kudonha kunowanzoitika nekuda kweimwe yeanotevera mamiriro - yakasununguka fittings;yakasakara zvisimbiso zvepombi kana kukundikana kwechisimbiso;nematambudziko emhando yemvura.
Imwe yeanonyanya kuoneka masosi ekuvuza ndeye loose fittings.Izvi zvinogona kuitika kana manifolds, hoses kana pombi fittings zvakatanga kuunganidzwa uye zvakabatana neTCU.Kuvuza kunogonawo kukura nekufamba kwenguva sezvo TCU ichiita zvekudziya uye kutonhora.Kugadzira chinongedzo-chakasimba, zvinogara zvakanaka ku:
• Ongorora zvose shinda yemurume neyemukadzi kuona kana ine tsvina kana kukuvara.
Isa sealant pashinda yechirume, uchishandisa mapeji matatu eTeflon (PTFE) tepi, wobva waisa chivharo chemvura yeplumber uchitangira pashinda yechipiri, saka shinda yekutanga yakatepwa inobata zvakachena.(Cherechedza: yePVC shinda, shandisa chete chisimbiso chemvura, sezvo iyo yakawedzerwa yakawanda yePTFE tepi kana paste sealants inogona uye inokonzeresa kutsemuka.)
• Kara shinda yechirume mushinda yemukadzi kusvika yasimba neruoko.Maka mutsara pamativi ese echirume/chikadzi chekubatanidza kuratidza nzvimbo yekutanga yekugara.
• Simbisa chinongedzo uchishandisa chipanera chinogadziriswa (kwete chipanera chepombi), uchishandisa chero TFFT (chigunwe-chinosunga 1.5 kutendeuka) kana chipanera che torque, uye nyora nzvimbo yekupedzisira yekusimbisa panzvimbo yakatarisana.
