How to Replace a Steam Radiator Air Vent
If your radiator air vent gets blocked, it won’t be able to effectively flush the air out of your steam vent, thus causing a whole host of problems with your heating (basically meaning that you won’t be getting much heat, if any at all). If you notice that your steam radiator’s air vent isn’t whistling as merrily as it used to, then it’s probably time to replace it. Keep reading to learn how.
Step 1- Buy a New Radiator Air Vent
Radiator air vents are readily available at any hardware store at a low cost. Take note of the model and make of your radiator when you go shopping to make sure you get the right size (size 5 is average for most models).
Step 2 - Close the Radiator
Use a wrench to shut off the incoming steam valve on your radiator to reduce the risk of burns.
Step 3 – Remove the Old Vent
Wrap a hand towel around the old radiator air vent, turn it counter-clockwise firmly, but steadily, and unscrew it out of place. If it’s stuck on too tight, try using pliers or a wrench.
Step 4 – Tape the Vent
Wrap a strip of Teflon tape around the threads of the new vent to prevent leaking.
Step 5 – Install the Vent
Screw the new air vent into place as firmly as you can by hand.
