Hello, I've ran JG speedfit 10mm pipe from new radiators up to the 22m plastic flow and return.
The flow and return is 22mm plastic (not JG Speedfit).
Can I still add my JG T's to the non JG pipe? And do I use JG inserts?
Many thanks

Thank you, I have no idea what manufacturer the 22mm pipe is, its been in the property for a number of years.

Thanks, I will have a closer look in the morning as its in the loft and I'll report back, thank you all again.
Hello, in the loft its 15mm gray plastic pipe (apologies in comes down to a 22mm).

I need to T in to this gray 15mm with JG speedfit 10mm pipe.

Would I use JG 15mm inserts on this pipe or something else?

Any advice appreciated.
