Hi, I've got two new screwfix Kudox radiators the same size, both are leaking from the threaded insert where it joins the casting. I installed with ptfe tape, and used the same amount on the other end. Both rads are leaking from one end, not the other which suggests it wasn't a great batch.
Is this to be expected? Should I just add more and more ptfe until it stops leaking, or should I return them?
Thanks
