Radiator valves may need replacing under several circumstances. Whatever the reason might be, it is essential to be informed about the process.
You can easily eliminate problems by hiring a professional to do the job. However, this is an expensive alternative as you can replace the valve yourself and it really doesn’t take much time at all.
If you do not wish to pay the extra money for a plumber and want to learn how you can easily replace radiator valves, read on.
You must understand that this task cannot be delayed as radiators refuse to heat when the valves are damaged. And, there’s really no reason to put it off.
Replacing these valves is a fairly simple procedure. If you are willing to work a little, you can soon enjoy a comfortable temperature at home.
Before you can start the work, make sure that you have all the tools needed. Along with the new valve, you will need spanner, wrench, spanner, hose, PTFE tape, wire wool and jubilee clip.
Once you have arranged all the items, you may have to drain the system, but it pays to read your manual first as this is not always necessary. For those who have the conventional cylinder tank system, professional assistance might be required.
Remove the Existing Valve and Old Adapter
Tightly grab the valve using a wrench. Carefully unscrew the cap-nuts with an adjustable spanner and then lift the valve.
Some water may leak out of the radiators while you do this so, it is recommended to lay rags below the valve. After removing the valve, clean everything well with the wire wool.
After that, unscrew the adapter from your radiator. To do this, use an adjustable spanner. A hexagonal radiator spanner might come handy for some radiators. Clean everything again.
Connect the New Adapter and Valve
Next, wind the PTFE tape about 5 times around the threads and then screw the new adapter to the radiator. Tighten it using a spanner.
Insert the valve cap-nut and then a new olive at the end of the pipe before fitting the new valve. Check if the valve is in line with the adapter.
With a wrench, grasp the valve body and then tighten the cap-nut which clamps everything together. Finally, you have to tighten the cap-nut which connects the valve with the water pipe.
Refill, Empty and Refill
Exactly below the boiler, you will find a filling loop. Your valve has been replaced. Turn it and continue to increase till the pressure gauge is at 1.5. After refilling the system, you have to bleed it out.
And once again, you have to turn the valve’s filling loop and refill it.
After following all these steps, your radiator will be ready for use again. These are simple steps and very few tools are needed. Replacing valves at home is very easy and inexpensive and it really is nothing to be worried about.
But with anything if in doubt our advice is to seek the help of a professional.
