Downstairs radiator, upstairs combi boiler, no tanks.
I just wanted to check that this order of steps was correct...
1. Turn off combi boiler.
2. Open bleed valve on rad to be replaced, to decrease total system pressure.
3. Isolate all upstairs radiators by closing one valve fully.
4. Isolate both radiator valves, and drain radiator.
5. Remove radiator and fixing.
6. Insert new radiator cap, bleed valve, and tails.
7. Measure up and fit new radiator to wall in correct position.
8. Make new valves ready w/ jointing compound (inside where olive meets), and set in closed position.
9. Swap old valves for new valves (hopefully reusing the old olive and nut).
9b. If needed, remove olive with hacksaw, clean pipe, and replace with new olive and nut and jointing compound.
10. Re-attach valves to radiator tails (here I may need to cut tail and/or use extensions, not sure of precise measurements as old rad is imperial)
11. Make sure all fitting are tight.
12. Open valves (check for leaks).
13. Turn on boiler, re-pressurize, and final test (fingers crossed).
