Half of the rads on my 10 rad system are not working and I've turned the system off prior to draining and flushing the 10mm plastic pipes. For the first time ever I have just looked closely the the 28mm manifolds and got very confused !
The are two, red painted, brass 28mm manifolds with 12 ports (4 ports on 3 sides) on each. They are connected together with a T piece. The T piece goes to the Return and the outer ends of the two manifolds go to the FLow from the boiler.
At first sight I couldn't see how it work UNLESS the manifolds have an internal blanking off plate, making each one a 2 x 6 port. Such labelling as there is, appears to conform to that.
But I can find no confirmation from current ads or images on the net that such manifolds exist. So, are there, were there ever, split, single block manifolds out there that explain this ? Thanks..
