Hi all
first time poster, so be kind, even when you read what I've done!
I'm having a kitchen extension done at the moment, we've opted for wet/screed underfloor heating throughout.
Our builder and a plumber set the system up and its been commissioning for a couple of weeks (we are gradually increasing the temperature and are now at 55c).
The system seems to be unbalanced and patchy - cold here, warm there, and most annoyingly, the room is not warm. Have tried a few things, flushing the pipes for air, shutting down one circuit to force water through the other etc... The next thing i want to try is to reduce return flow to the boiler to force more through the pipes.
I have also made sure the isolation valves on the manifold (where the pipes enter the floor) are fully open....
and here in lies the problem...... I think I have over turned one of them anti-clockwise.
the valve is adjusted by using a 5mm allen key under a grub screw. So screw out, allen in, full turn anti-clock and... woosh! water straight out the top.
turned back clockwise and it stopped, but now the fitting is loose and wont tighten, no water but it sits atop the opening and spins. Almost like the thread is not connecting.
I've uploaded a pic of the setup inc the manifold and where the value in question is.
I'll sum up my question in one word... help?
