(1) Mavavu omwe amagwiritsidwa ntchito papaipi yamadzi nthawi zambiri amasankhidwa motsatira mfundo izi:

1. Pamene kukula kwa chitoliro sikuposa 50mm, valve yoyimitsa iyenera kugwiritsidwa ntchito. Pamene m'mimba mwake chitoliro ndi wamkulu kuposa 50mm, valavu pachipata kapenavalavu ya butterflyziyenera kugwiritsidwa ntchito.

2. Pamene kuli kofunikira kusintha kayendedwe ka madzi ndi kuthamanga kwa madzi, valavu yoyendetsa ndi valve yoyimitsa iyenera kugwiritsidwa ntchito.

3. Mavavu a pachipata ayenera kugwiritsidwa ntchito pazigawo zomwe zimafuna kukana kwamadzi pang'ono (monga papaipi yoyamwitsa pampu yamadzi).

4. Mavavu a zipata ndi agulugufe ayenera kugwiritsidwa ntchito pazigawo za mapaipi kumene madzi amafunika kuyenda mbali zonse ziwiri, ndipo ma valve oyimitsa saloledwa.
5. Mavavu a butterflyndi mavavu a mpira ayenera kugwiritsidwa ntchito pazigawo zokhala ndi malo ang'onoang'ono oyika.

6. Ma valve oyimitsa ayenera kugwiritsidwa ntchito pazigawo za mapaipi zomwe nthawi zambiri zimatsegulidwa ndi kutsekedwa.

7. Chitoliro chotuluka cha mpope wamadzi wokulirapo uyenera kukhala ndi valavu yogwira ntchito zambiri

(2) Mbali zotsatirazi zapaipi yoperekera madzi ziyenera kukhala ndi mavavu:
1. Mapaipi operekera madzi m'nyumba zogona amachokera ku mapaipi operekera madzi a tauni.

2. Manode a panja mphete zapaipi network m'dera lokhalamo ayenera kukhazikitsidwa molingana ndi zofunika kulekana. Pamene gawo la chitoliro cha annular ndi lalitali kwambiri, ma valve a segmental ayenera kuikidwa.

3. Kumapeto kwa chitoliro cha nthambi cholumikizidwa kuchokera ku chitoliro chachikulu cha madzi a malo okhalamo kapena kumapeto kwa chitoliro chapakhomo.

4. Mapaipi apakhomo, mamita a madzi ndi zokwera nthambi (pansi pa standpipe, kumtunda ndi kumunsi kwa malekezero oyimirira a ringpipe network standpipe).

5. Mapaipi ang'onoang'ono amtundu wa chitoliro cha mphete ndi mipope yolumikizira yomwe imadutsa mumtundu wa chitoliro cha nthambi.

6. Poyambira paipi yogawa madzi yolumikiza chitoliro chamadzi am'nyumba kupita ku mabanja, zimbudzi za anthu, ndi zina zotero, ndi malo ogawa madzi papaipi ya nthambi 6 imayikidwa pamene pali malo atatu kapena kuposerapo ogawa madzi.

7. Chitoliro chotuluka cha mpope wamadzi ndi mpope wamadzi wodzipangira madzi.

8. Mapaipi olowera ndi otulutsira ndi kukhetsa mapaipi a thanki yamadzi.

9. Mapaipi opangira madzi pazida (monga ma heaters, nsanja zozizirira, etc.).

10. Mapaipi ogawa madzi a zida zaukhondo (monga zimbudzi, zokodzerakodzo, mabeseni ochapira, shawa, ndi zina zotero).

11. Zida zina, monga kutsogolo kwa valavu yowonongeka, valavu yochepetsera mphamvu, nyundo yamadzimadzi, magetsi othamanga, tambala wa sprinkler, etc., kutsogolo ndi kumbuyo kwa valve yochepetsera kuthamanga ndi kumbuyo kumbuyo, etc.

12. Valovu yokhetsa madzi iyenera kuyikidwa pamalo otsika kwambiri a netiweki yapaipi yamadzi.

(3) Thechekeni valavunthawi zambiri ziyenera kusankhidwa molingana ndi malo ake oyika, kuthamanga kwa madzi kutsogolo kwa valve, kusindikiza zofunikira zogwirira ntchito mutatha kutseka, ndi kukula kwa nyundo yamadzi chifukwa cha kutseka:
1. Pamene kuthamanga kwa madzi kutsogolo kwa valavu kuli kochepa, valavu yoyang'ana valavu, valve check valve ndi shuttle check valve iyenera kusankhidwa.

2. Pamene ntchito yosindikiza yolimba ikufunika mutatha kutseka, ndi bwino kusankha valve yotsegula ndi kasupe wotseka.

3. Pamene kuli kofunikira kufooketsa ndi kutseka nyundo ya madzi, ndi bwino kusankha valavu yotsekera phokoso lotseketsa phokoso kapena valavu yotsegula pang'onopang'ono ndi chipangizo chonyowa.

4. Chimbale kapena pachimake cha valve cheke chiyenera kutseka chokha pansi pa mphamvu yokoka kapena masika.

(4) Ma valve amacheke ayenera kuikidwa m'zigawo zotsatirazi zapaipi yamadzi:

Pa chitoliro cholowera; pa chitoliro cholowera madzi cha chotenthetsera chamadzi chotsekedwa kapena zida zamadzi; pagawo la mipope yotulutsira madzi ya thanki ya madzi, nsanja ya madzi, ndi dziwe lapamwamba pomwe polowera polowera paipi yamadzi ndi mapaipi otulutsira madzi amagawana payipi imodzi.

Zindikirani: Sikoyenera kukhazikitsa valavu yoyang'ana m'chigawo cha chitoliro chokhala ndi chitoliro choletsa kubwerera.

(5) Zipangizo zotulutsa mpweya ziyenera kuyikidwa pazigawo zotsatirazi zapaipi yamadzi:

1. Kwa maukonde operekera madzi omwe amagwiritsidwa ntchito pafupipafupi, zotengera zodziwikiratu ziyenera kuyikidwa kumapeto ndi pamwamba pa netiweki ya chitoliro.
valve ya gasi.

2. Kwa madera omwe ali ndi kusinthasintha kodziwikiratu ndi kudzikundikira kwa gasi mumsewu wapaipi yamadzi, valavu yotulutsa yokha kapena valavu yamanja yayikidwa pa nsonga ya dera kuti iwonongeke.

3. Pazida zopangira madzi othamangitsa mpweya, pomwe tanki yamadzi yotulutsa mpweya yodziwikiratu ikagwiritsidwa ntchito, malo okwera kwambiri a netiweki yapaipi yogawa madzi ayenera kukhala ndi valavu yotulutsa yokha.
