Pressure testing underfloor heating

[Fallout]

Do the flow valves shut open and close just be screwing them up and down?

Do the flow valves shut open and close just be screwing them up and down?

It'll confirm that in the manifold literature.

 

[Fallout]

are the flow regulators ok to turn on and off or should these of been set to a certain level by the installers

 

[Norcon]

If your at the purging stage then leave the regulators full open.

 

[Fallout]

why is this? Would you just turn the valves on the return on and off to flush separate zones through? Leaving all the flow valves open?

 

[Norcon]

No, one at a time as already explained.

 

[Richardthe3rd]

Yes.

You could test it to high pressure with air and if punctured during the screed laying will give an enormous swooooosh and maybe snake and whip lash round the room leaving the navvies in a state of shock and will be certain to be seen.

Oh FFS!! You trying to get Onetwat's blood pressure up again, he's on enough medication as it is!!
