Ma valve athu amadzi amapeza chilolezo cha WRAS

Madzi akumwa abwino ndi chinthu chofunika kwambiri panyumba ndi bizinesi iliyonse. Chifukwa chake, ndikofunikira kuti mutha kuwonetsa mosavuta zinthu zanu zapaipi zimagwirizana ndi malamulo.

WRAS, chomwe chimayimira Water Regulations Advisory Scheme, ndi chiphaso chosonyeza kuti chinthu chikugwirizana ndi mfundo zapamwamba zokhazikitsidwa ndi malamulo a madzi.

The Water Regulations Approval Scheme ndi bungwe lodziyimira pawokha la UK lopangira ziphaso ndi zida, kuthandiza mabizinesi ndi ogula kusankha zinthu zovomerezeka zomwe zimasunga madzi kukhala otetezeka.

Chitsimikizo cha WRAS chimaphatikizapo certification yazinthu ndi certification yazinthu.

1. Chitsimikizo cha zinthu

Kuyesa kwa chiphaso cha zinthu kumaphatikizapo zinthu zonse zomwe zimakumana ndi madzi, monga mapaipi amadzi, mipope, zida za valve, zinthu za mphira, mapulasitiki, ndi zina zotero. Zida zomwe zingagwiritsidwe ntchito popanga zida zogwirizana ziyenera kutsata British BS6920 kapena Miyezo ya BS5750 PART. Ngati zinthu zopanda zitsulo zikugwirizana ndi zofunikira za BS6920: 2000 (kuyenerera kwa zinthu zopanda zitsulo kuti zigwiritsidwe ntchito ndi madzi pokhudzana ndi anthu malinga ndi momwe zimakhudzira madzi), zikhoza kutsimikiziridwa ndi WRAS.

Kuyesa kwazinthu zofunikira ndi WRAS ndi motere:

A. Fungo ndi kukoma kwa madzi pokhudzana ndi zinthu sizidzasintha

B. Maonekedwe a chinthu chokhudzana ndi madzi sangasinthe

C. Sichidzachititsa kukula ndi kuswana kwa tizilombo ta m'madzi

D. Zitsulo zapoizoni sizidzagwa

E. Sizikhala kapena kutulutsa zinthu zomwe zimakhudza thanzi la anthu

Kuyesa kwazinthu kuyenera kutsimikiziridwa, apo ayi kuyezetsa kwamakina sikungachitike pachinthu chonsecho. Podutsa muyeso, makasitomala omwe amafuna kuti mankhwalawa agwirizane ndi miyezo yoyenera akhoza kukhala ndi chidaliro kuti mankhwalawa sangawononge madzi, nkhanza, kugwiritsa ntchito molakwika, kapena kuipitsa - magawo anayi a malamulo a madzi.

2. Chitsimikizo cha katundu

Zomwe zimapangidwira zimayesedwa molingana ndi miyezo yosiyanasiyana ya ku Europe ndi Britain komanso zomwe aboma akuwongolera kutengera mtundu wazinthu.

Mavavu agulugufe ndi ma valavu owunika amayesedwa malinga ndi EN12266-1, Mavavu okhala pansi osasunthika omwe amataya zero pamayeso onse akugwira ntchito komanso kuyesa kwa Hydrostatic pressure.
