Pipes groan, due to the fact that pipes are not secured down properly or that there are loose parts in the faucet or mixer.
choir members in your pipes
Probably an air-lock somewhere !
yes
no they are not
Pvc pipes are cheaper. They are easier to join. They last longer.
yes, as they heat up or cool down they groan
Yes they can. In general, however, the "groan" is not as bad as the "hammer." When water is suddenly forced through pipes containing a sharp bend, the water can hit the side of the pipe as if it's a wall. The force of the water can burst the pipes. Most modern plumbing fixtures account for this "hammering." But there are lots of old pipes out there too!

Loose Washer will do it every time, Or excessive velocity

groan
Water freezes at 0 deg C. As the water freezes in the pipes, it expands and it is the force of expansion which causes the pipes to burst.
Singing water pipes can be caused by air that is trapped in the pipes. The air can cause a whistling or singing sound, or it can cause the pipes to knock or rattle.
The audience groan at the cheesy joke.I hear him groan in pain.
The plural of groan is groans. As in "he groans as he realises it is Monday again".
I'm not familiar with rumbling in pipes, but the clanking of pipes when the heat starts up is a result of the pipes expanding because of the heat. Heat causes the metal to expand slightly, and the joints creak and clank when the heat makes its way through the pipes.
Groan means to moan or to be bored with something.
