What does it mean when your pipes are knocking? This is a question that many homeowners ask themselves, but may not know what the answer means. This article will discuss 11 reasons indicating that your plumbing system isn’t working properly!
What Does It Mean When Your Pipes Are Knocking: The 11 Reasons
1. Water Pressure
Water pressure can cause pipes to knock when water is flowing through them. The noise may be due to the physical movement of the pipe itself or from an object that’s caught in it, such as dirt or rust particles.
If you think your low water pressure might be causing knocking sounds, try turning off all faucets and appliances while a sink tap is running at full flow. But if other taps are still noisy even after closing everything else up tight, something stuck inside one of the pipes needs to get removed for this problem to go away.
If corrosion has built upon any part of your plumbing system over time, then chances are good that you’re going to hear some strange noises coming from your pipes.
This is especially true when water starts flowing through them and the corrosion rubs up against the metal pipe. In most cases, this type of knocking is a sign that it’s time for you to get your plumbing system replaced altogether.
3. Loose Pipes
If one or more of your pipes are loose, they can easily start making noise as soon as any kind of water flow begins. You’ll usually hear a high-pitched sound coming from the section of piping that’s moving around too much. The best way to fix this problem is by tightening all the screws and connectors that are holding the pipe in place.
4. Restricted Water Flow
When there’s not enough water passing through your pipes, they can start knocking against the sides as it tries to move through. This is often caused by a clog somewhere in the system, although there are other reasons why water flow might be restricted too. If you suspect that a clog is causing your pipes to knock, try using a plunger or plumbing snake to clear it out.
5. Bad Installation
If your plumbing was installed incorrectly from the beginning, it’s no wonder that you’re now hearing strange noises coming from your pipes. In some cases, this may mean that certain piping sections weren’t attached securely enough.
But if more serious mistakes were made during installation, then you could be looking at some bigger problems down the road.
6. Expansion and Contraction
When the temperature of the water inside your pipes starts to change, it can cause them to expand and contract. This, in turn, will create a knocking noise that’s usually quite loud. If you’re noticing this problem happening more often during the winter or summer months, then it might be time to have your insulation upgraded or install some new weather stripping around your doors and windows.
7. Damaged Pipes
If your pipes are damaged in any way, they’ll start making a lot of noise as soon as any water begins flowing through them. This could be due to anything from freezing cold temperatures to an accidental knock against a hard surface. In most cases, the best solution is just to replace the entire section of pipe that’s been damaged.
8. Sudden Pressure Changes
When you turn on a faucet or flush the toilet, there’s usually a sudden change in water pressure. And if your pipes aren’t strong enough to handle that kind of stress, they’ll start making noise as a way of warning you. If this is happening more often than not, then it might be time to get a plumber to come and install a pressure regulator valve.
9. Sloppy Soldering
Sloppy soldering can lead to all sorts of problems with your plumbing system, including knocking noises coming from the pipes. This type of issue is usually caused by too much solder being used during installation, which will eventually cause the pipe to break down over time. In most cases, this is a sign that you need to have your plumbing repaired or replaced altogether.
10. Loose Straps
If the straps that are holding your pipes in place are loose, they can easily start rattling and knocking against each other. This is usually a sign that the straps need to be tightened up or replaced altogether.
11. Old Age
In some cases, the noise coming from your pipes may just be a normal part of their natural aging process. As metal piping starts to corrode and wear down over time, it’s not uncommon for them to start making weird noises. If this is happening more often than not, then you might want to consider getting all your plumbing replaced before it completely fails on you.
If you’re still not sure what’s causing the noise, it might be a good idea to call in a professional plumber for help. They’ll be able to take a look at your pipes and determine the exact source of the problem. And who knows, they may even have some tips on how to fix it without having to replace the entire system!
