water hammer help! video included
Hello – I am a new homeowner with a steam system in an old house. This is my first winter in the house and the loud noises from the steam radiators make it very difficult to sleep. There seems to be only two bedrooms in the house that have loud radiators and they are both next to each other and are the last two radiators in the whole system to actually heat up and have any sort of steam noise coming from them. Both radiators are tilted towards the single pipe heading towards the floor (verified with a level). The valves on the floor are turned completely in the on position (at least from what I can tell). From what I can see, the water in the furnace is clear and I have tried lowering and raising the water level to try a different level. The PSI seems low (~2) on the furnace. All noises seem to be coming from the radiators and not from the pipes in the walls/floors.
Here is a link to a video which demonstrates the noise (usually lasts a few minutes):
I have tried searching through the forums and guides here but a lot of it seems complicated for someone not setting up a new system.
Anything to do to reduce this noise? Is this noise considered normal? Any tips are greatly appreciated!
