- Matabwa: ⅜” mabolts odutsa + mbale zochirikiza zitsulo
- Kutalikirana kwa Spigot: ≤1.5m (4.9 ft) ya galasi la 12mm (↑ kuchulukana m'malo omwe mphepo imawomba kwambiri)
- Chitsimikizo: Malipoti oyesera katundu a ASTM E2353 a chipani chachitatu akufunika
⚠️ Kuphwanya Malamulo Oletsa Kulephera
"Kuyang'ana kwapamwamba katatu kwalephera:
- Galasi losapsa mtima (limasweka kukhala mipeni)
