Pipe noises range from loud hammering sounds to high-pitched squeaks. The causes may be loose pipes, water-logged air chambers or water pressure that's too high. Anchoring exposed pipes is a simple solution. Other remedies such as anchoring pipes concealed inside walls, floors or ceilings, may call for a professional.

Pipes are usually anchored with pipe straps every 6 to 8 feet for horizontal runs, 8 to 10 feet for vertical. If your pipes bang when you turn on the water, you may need to add straps, cushion the pipes with a rubber blanket, or both. When you anchor a pipe, especially a plastic one, leave room for expansion. Do not use galvanized straps on copper pipes.

Only hot water pipes squeak. As the pipe expands, it moves in its strap, and friction causes the squeak. To alleviate this problem, cushion it as you would a banging pipe.

A hammering noise occurs when you turn off the water at a faucet or an appliance quickly. The water flowing through the pipes slams to a stop, causing a hammering noise. Check for loose pipes and anchor them. Also check for faulty air chambers. These lengths of pipe, installed behind fixtures and appliances, hold air that cushions the shock when flowing water is shut off. They can get filled with water and lose their effectiveness. To restore air to the chambers, turn off the water at the main shutoff valve. Open all the faucets to drain the system. Close the faucets and turn the water on again. The air chambers should fill with air. It is also prudent to check for water pressure that's above 80 psi (pounds per square inch). To lower the pressure, you can have your Sun Devil Plumbing professional install a pressure-reducing valve.
