Emmeti Multiplex technical datasheet May 2018 Can you connect a copper pipe to any of Emmeti Manifolds? Yes but we only cater for 10mm and 15mm pipe
Why should I use TopSan manifolds, instead of the Multiplex manifold? The TopSan was developed to allow more than 4-ways to be used without having to spend time on screwing together more than one manifold – for example if you are supplying two bathrooms from one set of manifolds, needing an 7-way for the cold supply (2 toilets, 2 basins, 2 showers and 1 bath) and a 5-way for hot (no toilets). Using Multiplex you would need a 4-way + a 3-way, and for the hot supply you would need a 3-way plus a 2-way – 2 more connections than you would have with a TopSan set of manifolds.
Can I use 10mm pipe for sanitary supply? This is simply a question of the available flow, pressure and pipe run length. It is now common practice to supply basin taps for example, with 10mm PB pipe over a reasonable distance of some meters.
Do I need to terminate at the manifold? No, you do not – simply continue through the manifold. Connect your flow in at one end and connect your flow out at the other end, instead of blanking the manifold off. Then continue your pipe run onto the final destination. Make sure overall you have enough flow to provide to more than one set of hot and cold manifolds.
How do I connect 22mm pipe? Our manifolds have a maximum internal diameter of 20mm, with an external diameter of 24mm. You cannot connect 22mm pipe to the outlets, but using a standard 1” or ¾” Male or Female BSP by 22mm compression adaptor, you can connect up 22mm copper or PB pipe to the inlet side. We have found over the seven years of using these manifold in UK new houses that you don’t need more then 15mm pipe for main unvented hot water cylinder supply.
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
What is the recommended pipe run length when installing sanitary hot water plumbing pipe? The UK Water Regulations say that hot water must reach the outlet within 30 seconds, and at a temperature of 50°C or above. The maximum length recommended is 12 metres for 15mm pipe. Therefore care needs to be taken when planning the location of the hot water source and manifolds. When the distances involved are greater, consider installing a ring circuit as a secondary circulating system, with a bronze circulating pump. This should be at least 28mm. Pass this through manifolds, with multiple tee-offs . Locate the manifolds within 12 metres of the outlets it will supply.
