Underfloor heating question

[Doobrey]

Ok,

Top manifold had cold water being pushed through via hose pipe

On top manifold, first valve fully opened, rest all closed.

On bottom manifold, first lockshield valve fully opened, rest all closed.

Water flowed...but the bottom host (with lockshield) never got cold.

Host?
Can you explain what that is?

Water flowed

Where too and how much?

You do have a drain hose connected?

 

[Doobrey]

So,

Top Manifold - Hose connected from outside tap - first valve open

Bottom Manifold - Drain hose connected to bucket - first valve open

Water flowed to bucket - slowly, not fast like the other loops

Cheers,

As said then, disconnect the offending loop (Don't touch the valves) and try purging this on its own.
If you can't make the connection then employ the services of a plumber.

going to do this.....

Thanks,
