Drop fed radiators

[600rob]

Recently had to drain my system to install some new rads.

Upstairs drained fine but i initially couldn’t get the downstairs rads to drain. I later found out from here that the downstairs rads were probably drop fed from above.

I only drained down the 2 ground floor rads that I needed to work on and left the remaining 4 which were still holding water.

The ground floor rads are fed from 10mm pipe that is buried in a concrete floor so I can’t really trace back the pipe work to see where it comes from.

Is there a way that I can find out whether or not all of the ground floor rads are drop fed? And would each rad be fed individually?

Cheers

Thermal imaging

This is the modern day method of locating concealed pipes and very useful for locating leaking water pipes in solid walls,floors ceilings etc.The equipment is available to buy or hire.

The other way to locate concealed pipes is "Experience"

Fair enough. I thought dan was winding me up.
Dan, i retract my comment.

So for a diyer like me without the latest equipment i guess its just a case of trying to find out as much as possible and trial and error when draining?

What did the pros do back in the day before this equipment wad around?

Hey 600Rob

Hey Rob, I wouldn't be so rude. Dan has a thermal imaging camera but I doubt it he would help you now.

if the pipes are hot, you can spray the concrete floor with water. It will darken as it is wet, then the pale shadow of the hot pipes will appear as their heat dries out the concrete above them.

Very useful it is too.

And that is through a thick carpet and underlay.
