Topsan Nickel Plated Brass Sanitary Manifold

Topsan sanitary manifold nickel-plated brass with taps. 24×19 threaded outlets.

The key advantage of the Topsan manifold is to allow greater than 4 outlets (up to 12-ways), without needing to bridge two or more Multiplex Manifolds together. This saves installation time.

Topsan manifolds offer a WRAS approved solution for plumbing to multiple outlets with an built-in tap for every circuit. Together with a range of WRAS approved Monoblocco connectors, the system can be used with almost all of the WRAS approved pipes sold in the UK. For applications where isolation is required at the manifold, this makes it the most comprehensive and flexible solution for hot and cold water plumbing either for new or for replacement/ refurbishment of domestic and commercial buildings.

Suitable for both plumbing and heating applications.

Can be supplied as a kit, including a mounting rail, wall brackets, pipe connectors, ball valves and blanking plugs.

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.

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.

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.

Is the TopSan manifold and fittings WRAS approved?

Yes, including all the connectors for pipe, WRAS reference 1006043, and it can be found on their website. (here)

Can I use the isolators to throttle flow?

They do have some impact on flow, particularly when reduced to below 50% of their fully open position. But this is considered not best practice. It is recommended that you fit flow regulators, that can be bought in the open market.

Can I fit the manifolds upside down?

Yes, in fact the more experienced installers prefer to do this. Generally pipe runs in point to point plumbed systems rise upwards to the roof/floor above, and pass through the roof space on the ground floor, then dropping down to termination points.
