(Inkcazo yesishwankathelo)Izilumkiso zofakelo kunye nokugcinwa kweevalvu zokhuseleko:
Izilumkiso zofakelo kunye nokugcinwa kweevalvu zokhuseleko:
(1) Isivalo sokhuseleko esitsha kufuneka sikhatshwe sisiqinisekiso sokufaneleka kwemveliso, kwaye kufuneka sihlaziywe kwakhona phambi kokufakwa, sitywinwe ngelothe, kwaye sikhuphe umlinganiselo wevalve yokhuseleko.
(2) Ivalve yokhuseleko kufuneka ifakwe ngokuthe nkqo kwaye ifakwe kwi-interface yesigaba segesi yenqanawa okanye umbhobho.
(3) Ukuphuma kwevalve yokhuseleko kufuneka kungabikho ukuxhathisa ukuphepha uxinzelelo lwangasemva. Ukuba i-drain pipe ifakwe, i-diameter yayo yangaphakathi kufuneka ibe nkulu kunobubanzi bokuphuma kwevalve yokhuseleko. Indawo yokukhupha yevalve yokhuseleko kufuneka ikhuselwe ekukhenkceni, enokutsha okanye enetyhefu okanye enetyhefu kakhulu kwisikhongozeli. Isitya sombhobho ophakathi kunye nombhobho wokukhupha amanzi kufuneka ukhokele ngokuthe ngqo kwindawo ekhuselekileyo yangaphandle okanye ube nezixhobo zokulahla ngokufanelekileyo. Umbhobho wokukhupha amanzi wevalve elawulayo oziqhubayo awuvumelekanga ukuba uxhotyiswe nangayiphi na ivalve.
