Question:what couses the pipes to rattle?
Answers:
Not enough clamps holding the pipe in place or if they are making a very loud knocking noise you'll need a small baffle or
Water Hammer Arrestor installed.
Its A device installed near a fixture to absorb the hydraulic shock that happens when a fixture's supply is suddenly shut off, causing water hammer, a loud banging noise in the pipes.
Most states now require an arrestor or baffle installed near to the water heater to meet the newest BOCA plumbing code.
Water hammer. Turning off the water too fast.
Check the pipe that is rattling. Are there enough mounting clamps holding it snug to the beams, wall, etc. That will cause them to rattle if they are not mounted properly.
Normally air in the line. It has to be bled out. At the bleeder valve on radiators or the highest water valve in the house usually a sink.
usualy diferentiating water pressure in the pipes. for example if the normal pressure in a pipe is 75 psi, and you open a fauset it drops because the pressure is being releasesd... usualy a drop in pressure does not move pipes as much as sudden increase... somuch more likely to move when you shut the water off and the pressure goes back up fast.
there are situations where the water coming into pipes surges... like when some other water on the system is turned on or off, if there might be air in the lines, it the temprature of the waer in the line changes suddently ( like water is warm from sitting in the pipe, and cold water replaces it)
could go on and on, but basicaly it is an unusual differance in the pressure for whatever reason
