Step 1: You Will Need
- Old Rags
- Large Bowl
Step 2: Drain Water
Turn off both valves then unscrew the cap-nut that keeps the valve attached to the adaptor in the end of the radiator. Hold the bowl under the joint and open the bleed valve slowly to let the water drain out. Transfer the water from the bowl to the bucket, and continue doing this until no more water can be drained off.
Step 3: Lift Radiator from Brackets
Unscrew the cap-nut that keeps the other valve attached to the radiator, lift the radiator free from its wall brackets, and drain any remaining water into the bucket
If you have thermostatic radiator valves, or TRVs, make sure you cap them off at this point. Do this because TRVs open automatically as the room gets colder so could cause a leak if the radiator's not in place
Step 4: Replace Radiator
To replace the radiator, re-hang the radiator and tighten the cap-nuts on both valves. Last of all, bleed the air from the radiator. For this, see "How To Bleed A Radiator".
