Usually, tapping noises that come from pipes deduce a problem with water flow or water pressure. Two of the most common causes are water hammers and trapped air bubbles. A water hammer, also known as a hydraulic shock, occurs when moving fluid suddenly stops when a faucet or valve is turned off. This gurgling or tapping sound may be an indication of an obstructed passage in the pipe itself.
It could be a real piece of plastic or other object that fell down the drain, or something as simple as the accumulation of soap or dirt on the pipes. Gurgling usually comes from drain pipes. This sound occurs when water cannot drain properly, usually when there is an obstruction in the water pipes. Blockages in drains are often due to hair, grease, soap scum, or objects falling down the drain.
They can occur suddenly or build up slowly over time. Hydraulic hammers are one of the most common problems with noisy pipes. They occur when the water supply is shut off and the high pressure in the pipes causes the water inside to hit the shutoff valve or the walls of the pipe. Noise is a distinctive hammer and usually only occurs after turning off a faucet or appliance.
Noisy water pipes can also be caused by loose pipes in the house. Every home has a complete piping system of valves and other elements that depends on many tiny parts and pieces to allow everything to work as it's supposed to work. This is something that can be a homemade solution, since you tighten the fasteners to keep things in place, fix your noisy water pipes and save yourself from future plumbing problems. The build-up in the pipes reduces space for water, which can cause squeaks when water tries to get through the pipes.
Another source of the dreaded water pipe squeak could be your home's main shutoff valve or water pressure regulator, especially when the noise seems to be resonating throughout the house. When you are at home, expect the pipes in your plumbing system to carry hot and cold water to all parts of your house at your disposal. That said, water hammers can and do sometimes occur in the form of much smaller blows to pipe lines with shut-off valves, so it's important to have it analyzed by a professional plumber to determine exactly where it comes from. What can happen is that the fasteners that hold the pipes to the studs in your house come loose and, when the hot water from the water heater flows through copper tubes, it will expand and move slightly.
Then, when the water flow from the water heater stops, it cools down and the copper pipe returns to its place. rubs against the strut and causes noises in the pipes. To make matters worse, loud noises coming from pipes can be an indicator of a faulty plumbing problem or of a series of plumbing problems in the pipes. Since supply pipes usually have plaster walls, homeowners don't usually want to tear anything out to cover those pipes.
While there are many causes, there are some that appear time and time again in noisy pipes and plumbing systems that are worth knowing about. If you have pipes that buzz from only one part of your home or from a single unit in an apartment building, the cause could be worn parts related to the pipes. In addition, when pipes expand and contract because the pipes heat up or cool, strange noises can occur. When it comes to strange noises in homes, few things can make the kinds of sounds that water pipes make when things aren't the way they should be, and for young or first-time homeowners, it can be downright strange when pipes make noise.
