Very short water hammer
Our one pipe steam system is usually very quiet. I went around and adjusted the vents on our radiators the other day by increasing the ones on the largest radiators and decreasing the ones on the smaller ones.
We have all mains vented with big mouths.
Over the last few days I’ve noticed that after the system has run for about 10 minutes, there are usually 2 sharp raps of water hammer and maybe a third not as loud one. Then the system is quiet for the remainder of the time it is running.
What would cause it to happen like that? It’s very hard to pinpoint exactly where it’s coming from because it stops so quickly. Thanks
