What is this? And what does it do?

Glyn Barr · Feb 12, 2019

Hi all. I'm currently renovating a old 60's house and was rooting around under the floor boards and found this, see picture. It looks a bit tired and possibly due to fail but unsure what it is. I think it's too do with the heating system but not sure. Help!!!!!

Sorry still trying to upload picture.

I'm not sure about this but my guess is that is the return manifold for an underfloor heating system. The corrosion on the outside is interesting in itself. It looks like dezincification, which has left the brass body porous and corrosion coated. (I suppose it could be paint that has photographed strangely.)

The foam pipe insulation looks a bit more recent than the 1960s to me, 1980s perhaps.

Looks like an old heating manifold. Lots were used for 10mm systems.

How long has microbore been around?

It must feed the radiators downstairs then as I don't have underfloor heating any where in the house. I'm no expert but it looks like it needs replacing.
What would be a suitable replacement?

Maybe something like this.

I’m no UFH specialist but, is that not an UFH manifold? You want one for heating.

I never used them. I always used fittings.

Just use 22mm by 10 or 8mm tees

Since about @townfanjon's team last won a game. About the 1600's ...

I put Microbore in my own house in 1975, there was plenty of it about then.
Being a cheapskate I used these, (2 needed to replace the split type) which appear to still be available, whereas the Yorks split as O.P are discontinued, pic shows 22mm x 10mm O.P could be 28mm and or 8mm

Ok so there a simple device that splits the flow. Ideal. I didn't know if they had any other fancy innards that did magical things.

I needed to replace one about 5 years ago. Merchants wanted over 40 notes for the Yorkshire split manifold. Used 4 of them from Tool station.

What is this? And what does it do?
