A range of WRAS approved nickel plated, extruded brass manifold in ¾”, 1”and 1¼” inlet sizes, suitable for heating and hot water applications where isolation at the manifold is not required. Topway SN allows up to 12-way as a single piece without interconnecting 2 or 3, 4-way manifolds.

Can you connect a copper pipe to any of Emmeti Manifolds?
Yes but we only cater for 10mm and 15mm pipe

Can Emmeti sanitary manifolds be disinfected in accordance with HSE ACOP L8* with a chemical giving rise to a free chlorine level of 25-50mg/l?
Providing that the chemical disinfection regime is carried out in strict accordance with HSE ACOP L8, we are prepared to guaranteee the life of our sanitary manifolds for a period of 10 years from the date of commissioning the system. *This is to prevent the growth of Legionella bacteria in sanitary water systems which can cause a potentially lethal infection in humans
