How can you tell the in and out feeds of a rad All aspects of plumbing questions and answers, help, tips and information

Hi

Due to money shortage I stopped my plumber installing rads in my upstairs some 12 months ago. He left two 22mm pipes sticking up throught the floor. I how want to connect raditors upstairs but do not know what is the in pipe or out pipe. Is there any easy way of telling before I rip even more laminate flooring up.

Why do you need to know ?

as long as you have
1 x flow
and
1 x return
To each radiator it'll work

Some thermostatic valves are directional but most modern one are not so with new valves any way will do

Hi JM

as hamish said most modern TRV can go either side, look for the arrow on the vlave body to check, usually left is flow and right is return
