How do I stop my steam pipes from banging?
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.
Why are my steam radiators 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.
How do I stop my pipes from knocking when heating is on?
A simple solution, that should fix the problem of banging pipes, is to squash some felt around each pipe under your floorboards. Try and concentrate on every place where a pipe touches a joist or another pipe and wrap a little felt around it to create a snug fit.
How do I fix water hammer steam heat?
If steam can work it’s way down the equalizer and into the wet return it will hammer, and usually at the end of the cycle. See if there’s a long nipple on the Hartford Loop. Long nipples create water hammer as the condensate returns. Replace the long nipple with either a close nipple or a wye fitting.
What causes my central heating pipes to knock?
Trapped air in the heating system Over time and lots of use, air can creep into your central heating system and, when enough air gets trapped, it can cause your pipes and system to make noise. Water and air flowing through pipes and radiators can result in clicking, ticking or tapping noises.
Why does my heating system make a banging noise?
The ducts that send warm air throughout your home are made of thin metal. The metal can expand when heated and will contract as it cools down after the furnace cycles off. As the metal ducts expand, they typically make a banging or booming noise.

What causes water hammer in steam heating system?
Water Hammer caused by the sudden condensation of steam When steam loses its heat, it turns into condensate, whose specific volume is more than 1000 times smaller than that of steam. So when steam comes into contact with colder condensate and condenses, its volume is instantly reduced to next to nothing.
How do you stop a steam header from hammering?
Prevention of steam hammering
- Ensure correct steam and condensate design.
- Have documented SOP’s (standard operation procedures) for steam system start-ups and shut downs.
- Proper training for plant personnel.
- Have installation standards for steam components.
