Removing a radiator in your home with this simple ‘how to’ guide – this is helpful if you are about to decorate!
Turn off BOTH valves, fully clockwise (don’t worry about a small drip from the top of the valve, as the washer moves to the valve seat). The other valve usually has a push-on plain plastic cover, that can be pulled off, to reveal the valve shaft. You can usually pull off the knob from the other valve, and push it on to this one to close the valve. If you cannot do this, use pliers on the flat part, turning clockwise until it stops,BUT DO NOT USE A LOT OF FORCE.
Open the bleed valve one or 2 turns
Ensure that you have an old towel and the ice-cream container in place under one of the valves, and slowly loosen the large nut near the radiator, using the spanner (SEE THEPICTURES BELOW). You might need to position the nut in order to get a good downwards trickle into the container.
When the container is about half full, empty into the bucket.
Repeat until the water is just a slow drip.
Loosen the other nut. Some more water may flow out. You can fully undo the nuts, and spring back the pipe carefully (just a bit!), to ensure that there is none trapped.
If the radiator is a large and/or heavy one, you are recommended to have a colleague help you lift it up and away from the wall brackets.
IT IS IMPORTANT TO KEEP THE RADIATOR HORIZONTAL, then SLOWLY tilt it over the bucket. You will be amazed at the sludge and rusty bits that come out
Twist some kitchen roll into each open end of the radiator, and place on to the old towels, ensuring that no water leaks on to carpets. NOTE: The iron oxide in the dirty sludgy water is a very difficult stain to remove from carpets, so great care is needed here.
When ready to put it back, place the radiator on the brackets, tighten up the 2 large nuts, and open both valves whist carefully checking for leaks. If there are no signs of leaks, then bleed the radiator of all air, tighten the bleed screw, and recheck over the next few hours for leaks. NOTE THAT IF YOUR SYSTEM IS A COMBI MAINS PRESSURISED BOILER, THEN YOU WILL NEED TO USE THE COMBI FILLING-LOOP VALVES TO BRING THE SYSTEM PRESSURE BACK UP TO 1.2 TO 1.5 BAR WATER PRESSURE (SOME BOILERS WILL NOT FIRE UP IF THE PRESSURE IS TOO LOW).
