When we flush the toilet, or turn the water on it make a loud sound.?
Answers:
It is called "water hammer". There is a little gadget called a "water hammer arrester" that will prevent it. It usually happens at the highest fixtures on a vertical supply line when they are opened. A knowledgable plumber will install them during the original installation...

It means you need new pipes.

what???????
hmmmmmmmmmmmmmm, tough one! Maybe your pipes are too thin.
Its just letting everybody in the house know we used the toilet!
old system, secure the lines to the walls
If its a banging sound it might be 'hammer pipe' (or its called something like that). We had it and had a spring put in near one of our pipes so that it wouldn't bang so much. It is basically a pipe that is banging inside the wall and the spring thing took the shake out of the pipe. We just told the hardware store guy and he new what to do and we installed it ourselves. Hope that helps.
pipes are hammering? loose,water presure,need expandtion tank
It can be air in the pipes. If you have a relief valve, bleed off some of the air and you will be all set.
THE HAMSTER SURVIVED IN THE SEWER AND IS COMING BACK FOR REVENGE
You have water in the hammer arrester. Turn off the water to the house, turn on a low faucet like a basement or bathtub and open any other faucet in another room. Wait ten minutes, shut your faucets off, turn on the water, open your faucet to bleed out the air. That should stop the hammer.
sounds like you need to bleed the lines and get some air out. This happens a lot in older homes and also a plumber can help you with this but costs money. We just open all the faucets just a little in the house then turn them all off, then go back and run them a little and it will release all the air pockets usually.
Newton's law states that for "every action there is an equal and opposite reaction." If water is flowing into a faucet then is suddenly shut off, the kinetic energy of the flowing water reverses direction and must be dissipated during the transition to a steady state. This energy is initially reflected back through the plumbing system in a direction opposite to the original flow, creating an oscillating shock wave. Depending on the extent of the shock wave, a loud banging or rattling sound can be heard as pipes expand and move as the shock wave dissipates.
If there were no friction losses and if the pipes had no expansiveness, the shock wave would continue indefinitely. However, as water flows through the pipes, friction due to internal pipe surface irregularities helps to slow the water, resulting in energy that is converted to heat. In addition, virtually all pipes -- including drawn copper tubing -- have some measure of elasticity. As the plumbing system encounters a sudden pressure shock wave, the pipes expand slightly to absorb the shock. Pressures in excess of several thousand PSI are possible during this brief instant, which is why water hammer can burst pipes and joints unexpectedly.
if by slowly opening the tap immediatly has an effect on the noise then this is definately water hammer, generally caused by poor pipe bracketing .simply trace the noise to where it is at its worst and place some additional clips available from your local plumbers merchants and you could solve this one as a diy project for a couple of penniesif it still continues then look into changing the ball valve in the toilet cistern
