(2) Izingxenye ezilandelayo zepayipi lokuphakela amanzi kufanele zifakwe amavalvu:
1. Amapayipi okuhambisa amanzi ezindaweni zokuhlala ethulwa ngamapayipi okuhambisa amanzi kamasipala.

2. Ama-node wenethiwekhi yamapayipi endandatho yangaphandle endaweni yokuhlala kufanele abekwe ngokuvumelana nezidingo zokuhlukaniswa. Uma ingxenye yepayipi ye-annular yinde kakhulu, ama-valve esigaba kufanele afakwe.

3. Isiqalo sepayipi legatsha elixhunywe epayipini elikhulu lokuphakela amanzi lendawo yokuhlala noma ekuqaleni kwepayipi lasendlini.

4. Amapayipi asekhaya, amamitha amanzi nezikhuphukeli zamagatsha (phansi kombhobho omile, iziphetho ezingaphezulu nezingezansi zepayipi elimile lenethiwekhi yamapayipi ayindilinga).

5. Amapayipi angaphansi kwesiqu senethiwekhi yamapayipi ayindandatho kanye namapayipi axhumayo ahamba kunethiwekhi yamapayipi egatsha.

6. Indawo okuqalwa kuyo ipayipi lokusabalalisa amanzi elixhuma ipayipi elihambisa amanzi elingaphakathi ezindlini, izindlu zangasese zomphakathi, njll., kanye nendawo yokusabalalisa amanzi epayipini legatsha lokusabalalisa 6 ibekwa uma kunezindawo zokusabalalisa amanzi ezi-3 noma ngaphezulu.

7. Ipayipi lokuphuma lepompo lamanzi kanye nepompo yokumunca yepompo lamanzi elizilungisayo.

8. Amapayipi okungena nawokukhipha kanye namapayipi okudonsa amanzi ethangi lamanzi.

9. Amapayipi okuhambisa amanzi emishini (njengamahitha, imibhoshongo yokupholisa, njll.).

10. Amapayipi okusabalalisa amanzi ezinto ezisetshenziswayo zokuhlanzeka (njengezindlu zangasese, izindawo zokuchamela, izitsha zokugezela, amashawa, njll.).

11. Ezinye izesekeli, njengengaphambili le-valve yokukhipha i-othomathikhi, i-valve yokunciphisa ingcindezi, isinqamuli sesando samanzi, i-pressure gauge, iqhude le-sprinkler, njll., ngaphambili nangemuva kwe-valve yokunciphisa ingcindezi kanye ne-backflow preventer, njll.

12. Ivalvu yokukhipha amanzi kufanele ifakwe endaweni ephansi kakhulu yenethiwekhi yamapayipi okuhambisa amanzi.

(3) Ihlola i-valvengokuvamile kufanele kukhethwe ngokuya ngezinto ezifana nendawo yokufaka kuyo, ingcindezi yamanzi phambi kwevalvu, izidingo zokusebenza zokuvala ngemva kokuvalwa, kanye nobukhulu besando samanzi esibangelwa ukuvala:
1. Uma ingcindezi yamanzi phambi kwe-valve incane, i-valve yokuhlola i-swing, i-valve yokuhlola ibhola kanye ne-shuttle check valve kufanele ikhethwe.

2. Uma ukusebenza kokuvala okuqinile kuyadingeka ngemva kokuvala, kuhle ukhethe i-valve yokuhlola ngentwasahlobo yokuvala.

3. Uma kudingekile ukwenza buthaka futhi uvale isando samanzi, kunconywa ukukhetha i-valve yokuhlola yokuvala umsindo evala ngokushesha noma i-valve yokuhlola evala kancane ngedivayisi yokuthambisa.

4. I-disc noma i-core ye-valve yokuhlola kufanele ikwazi ukuvala ngokuzenzakalelayo ngaphansi kwesenzo samandla adonsela phansi noma entwasahlobo.

(4) Amavalvu okuhlola kufanele afakwe kulezi zigaba ezilandelayo zepayipi lokuphakela amanzi:

Epayipini lokungena; epayipini lokungena kwamanzi le-heater yamanzi evaliwe noma imishini yamanzi; engxenyeni yepayipi elikhipha amanzi ethangini lamanzi, umbhoshongo wamanzi, kanye nedamu eliphansi eliphansi lapho ipayipi lokuphuma kwamanzi eliphumayo kanye namapayipi aphumayo ahlanganyela ipayipi elilodwa.

Qaphela: Akudingekile ukufaka i-valve yokuhlola engxenyeni yepayipi ifakwe i-pipe backflow preventer.

(5) Imishini yokukhipha umoya kufanele ifakwe ezingxenyeni ezilandelayo zepayipi eliphakela amanzi:

1. Kuhleloxhumano lwamapayipi okuhambisa amanzi asetshenziswa ngezikhathi ezithile, amadrayini azenzakalelayo kufanele afakwe ekugcineni nendawo ephakeme kakhulu yenethiwekhi yamapayipi.
i-valve yegesi.

2. Ezindaweni ezinokuguquguquka okusobala kanye nokunqwabelana kwegesi kunethiwekhi yamapayipi okuhambisa amanzi, i-valve yokukhipha i-othomathikhi noma i-valve ye-manual ifakwe endaweni ephakeme kakhulu yendawo ukuze ikhiphe.

3. Ngomshini wokuphakelwa kwamanzi omfutho womoya, lapho kusetshenziswa ithangi lamanzi lomfutho womoya ozenzakalelayo, indawo ephakeme kakhulu yenethiwekhi yamapayipi okusabalalisa amanzi kufanele ifakwe i-automatic exhaust valve.
