Bleed the Pipes “Bleeding” your steam radiator pipes is an effective way to remove trapped air that causes banging or knocking sounds. Turn off your heat and give your system time (30 to 60 minutes) to cool. Using your radiator key, turn the valve on your radiator to release built up pressure.
How do you stop a steam pipe from hammering?
The most important way to prevent water hammer is to remove the water from the steam lines before passing the steam again through them. Water is removed from the steam lines using drain connections. All the water should be drained out to make the lines clear.
Why do steam pipes hammer?
The phenomenon of steam hammer generally occurs when there is direct contact of steam vapor with a liquid at its subcooled state. This is typically seen in applications where steam is directly sparged into a tank or injected into a process pipe.

What causes steam heat banging noises?
That is why all steam pipes must slope downward toward the boiler; if they don’t, water will be trapped in the pipe and this can result in banging or hammering noises every time the steam comes up – the incoming steam tries to force its way past the trapped water and this causes the water to bang around or ”hammer” …
What is radiator hammer?
Radiator valve hammer is caused by a high velocity of water dragging down the spring loaded plunger of a TRV (thermostatic radiator valve). The return spring in the plunger will always try to lift the mechanism and if the water flow is strong enough, it will try to drag the plunger down.
How does a steam hammer work?
A single-acting steam hammer is raised by the pressure of steam injected into the lower part of a cylinder and drops under gravity when the pressure is released. With the more common double-acting steam hammer, steam is also used to push the ram down, giving a more powerful blow at the die.

How do you stop water hammer?
Some of the best ways to prevent and solve future water hammers include:
- Drain your pipes and refill them to create new air chambers. One method for eliminating water hammers is to create new air chambers that will serve as cushions for shockwaves.
- Tighten mounting straps.
- Install a water hammer arrestor.
Why are my radiator pipes banging?
When radiators in a hot-water system develop banging or hammering noises the problem is most often due to trapped air that cannot get out. Air gets into the system from the fresh water that is periodically added to the system (usually automatically) to replace water that evaporates or leaks out.
Why do my pipes sound like knocking?
A: The knocking sounds are what’s known as water hammer, caused when water flowing in pipes suddenly shuts off and vibrates with enough force to cause the pipes to knock against wood framing.
