How can I get 22mm take off connections on your Topway manifolds?

They are not designed for this, taking pipe only up to 20mm. However, if you wish, you can remove our take off connectors, taking care to not exert too much pressure and damaging the manifold in the process. They are factory glued in, but can be removed with care. Replace them with 1/” MBSP x 22mm copper compression connectors manufactured to BSEN 1254-2.  We recommend contacting Muller Primaflow (, product code 22009005 brass.
