Underfloor heating manifold

[kevin A]

Hi all.
We have underfloor heating on a couple of levels in our house. One floor was not heating and I asked advice from a plumber we have used before. I sent him pictures of the manifold in question. While this was going on I switched off fuses and replaced batteries etc. The heating has kicked into life (Yay!) but the plumber noticed a problem with the manifold from the picture. He thinks it has been plumbed in wrong but everything is working! Does it look right to you? It looks no different from the other manifold which has always worked fine. Any advice appreciated.

I think, if you switch the handles on the valves and send him a photo, he might say it looks right.

That's as long as the bottom header gets warm first or the hotter of the 2 headers.
If not, it has been installed incorrectly

Thank you, i think that is what is confusing him. The floors getting nice and warm so can't see it being an issue. Checked the neighbours and it is identical apart from the handle colours.
