Melemo ea Backflow Preventers

Ba thibelang ho phalla ha moraophetha karolo ea bohlokoa ho sireletseng litsamaiso tsa mokelikeli, haholo-holo phepelo ea metsi a nooang, ka ho thibela ho phalla ka morao ha mecha ea litaba e silafetseng kapa e sa rateheng. Melemo ea bona ea bohlokoa e kenyelletsa:

1. **Tshireletso ea Boleng ba Metsi**

Molemo o ka sehloohong ke ho thibela tšilafalo pakeng tsa lisebelisoa tsa metsi a nooang le mehloli e sa noeeng (mohlala, litšila tsa indasteri, metsi a nosetso, kapa likhoerekhoere). Sena se tiisa hore metsi a nooang kapa maro a hloekileng a lula a sa silafala, ho fokotsa likotsi tsa bophelo bo botle tse amanang le tšebeliso ea metsi a silafetseng.

2. **Tlaelo ya Taolo**

Libakeng tse ngata, ba thibelang ho phalla ha morao ba laetsoe ke melao ea tsamaiso ea metsi le melao ea bophelo bo botle (e kang e behiloeng ke mekhatlo e kang EPA kapa ba boholong sebakeng sa metsi). Ho li kenya ho thusa lits'ebeletso le lits'ebetso ho fihlela litlhoko tsa molao, ho qoba likotlo kapa ho koaloa ha ts'ebetso.

3. **Redundancy and Reliability**

Boholoba thibelang ho khutlae na le li-valve tse peli tsa ho hlahloba le valve ea liphallelo, e leng se etsang hore ho be le mokhoa o sa hlokahaleng oa tšireletso. Haeba karolo e le 'ngoe e hlōleha, tse ling li sebetsa e le li-backups, ho fokotsa kotsi ea ho khutlela morao. Moqapi ona o tiisa ts'ebetso e tsitsitseng esita le tlas'a khatello e feto-fetohang kapa maemo a phallo.

4. **Tlhahlobo ho Lits'ebetso tse fapaneng **

Li ikamahanya le maemo a fapaneng, ho kenyeletsoa lits'ebetso tsa bolulo, tsa khoebo, tsa indasteri le tsa masepala. Ho sa tsotellehe hore na ho sebelisoa marang-rang a lipeipi, mekhoa ea ho nosetsa, kapa mekhoa ea mekhoa ea indasteri, ba thibelang ho khutlela morao ka katleho ba thibela ho khutlela morao ho sa tsotellehe mofuta oa mokelikeli (metsi, lik'hemik'hale, joalo-joalo) kapa boholo ba tsamaiso.

5. **Ho Fokotsa Tšenyo ea Thepa**

Ka ho emisa ho phalla ho khutlela morao, ba thibelang ho khutlela morao ba sireletsa lipompo, li-boilers, li-heaters tsa metsi, le likarolo tse ling tsa tsamaiso ho tloha tšenyo e bakoang ke ho khutlela morao kapa hamore ea metsi (ho phahama ha khatello ea tšohanyetso). Sena se eketsa nako ea bophelo ba lisebelisoa le ho fokotsa litšenyehelo tsa tlhokomelo.

6. **Mosebetsi o Ikemetseng**

Ba thibelang ho phalla ha moraosebetsa ntle le ho kenella ka letsoho, ho arabela hang-hang ho liphetoho tsa khatello kapa ho fetoha ha phallo. Sena se tiisa ts'ireletso e tsoelang pele ntle le ho itšetleha ka ho beha leihlo batho, ho ba etsa hore ba tšoanelehe bakeng sa litsamaiso tse sa sebetseng kapa tse hole.

7. **Katleho ea Litšenyehelo**

Le hoja litšenyehelo tsa pele tsa ho kenya li teng, ho boloka nako e telele ho bohlokoa. Ba fokotsa litšenyehelo tse amanang le tlhoekiso ea tšilafalo ea metsi, tokiso ea lisebelisoa, likotlo tsa taolo, le molato o ka bang teng liketsahalong tsa bophelo bo botle tse amanang le metsi a silafetseng. Ha e le hantle, ba thibelang ho khutlela morao ba bohlokoa haholo bakeng sa ho boloka botšepehi ba tsamaiso, bophelo bo botle ba sechaba, le katleho ea ts'ebetso ho pholletsa le mefuta e mengata ea lisebelisoa tse thehiloeng mokelikeli.
