By doing this you’ll be improving the efficiency of your heating system.
Watch the video guide or follow the simple steps below for full instructions on how to install TRV’s to a radiator.
Before buying TRV’s you’ll need to decide what style you want – angled or straight – use our Radiator Valve Guide to help you make the right choice.

So let’s get started on putting some new valves on your radiator!
Step 1 – Remove The Old Valve
Begin by removing the old radiator valve and tail using the pump pliers and an adjustable spanner.
Step 2 – Cut The Olive
Using the hacksaw cut a line through the olive, but be careful not to nick the copper pipe.
Step 3 – Split & Remove The Olive
Using the flat-headed screwdriver split the olive and remove it.
Step 4 – Wrap Up Your New Valve Tail
Once that’s done, wrap the PTFE tape clockwise around the radiator valve approximately 17 times.
Step 5 – Insert Tail & Fit Valve
Put the valve onto the tail and knock it on with the adjustable spanner to ensure it’s fully pushed into the valve.
Then, hold the valve with the pump pliers and nip up the tail nut using the adjustable spanner.
Once the TRV’s are fitted you’ll then need to fill the system back up.
