Understanding Pipes Making Noise When Water Is Turned Off

Pressure changes in the internal plumbing system of your house occur when water flow is suddenly stopped. Preferably, your pipes are supposed to take such pressure without a murmur. However, when something isn’t functioning correctly, pipes making noise when water is turned off becomes a recurring issue.

This issue is common particularly in households that have:

·         Older plumbing systems

·         High water pressure

·         Loose or aging pipe supports

·         Rapid opening appliance valves.

Even homeowners tend to think that it is a normal noise but it is actually your plumbing system crying out.

Pipes Making Noise When Water Is Turned Off - Causes, Fixes, and When to Call a Professional 3

There isn’t just one reason behind pipes making noise when water is turned off. The following are the most frequent offenders that we encounter during professional inspection.

Water Pressure Exceeding the Necessary Level.

High pressure of water causes the pipes to take in more shock as the valves are closing. It usually causes the water pipes to bang when turned off particularly around wash-machines and dishwashers.

Loose Pipe Mounting

Pipes are occasionally not firmly attached to framing and therefore are free to move. The motion causes a knocking effect in the pipes of water, or the rattling effect upon the shut off of water.

Worn-Out Air Chambers

The older systems use air chambers to accept pressure. These chambers become useless as time goes by due to their filling with water and causing water hammer in pipes.

Faulty Valves

A common complaint of banging pipes plumbing problems is associated with a type of appliance that has a fast-closing solenoid valve.

How Water Pipes Banging When Turned Off Develop Over Time

The water pipes making noise when water is turned off sometimes becomes a important issue to be highlighted because it grows with time as a result of wear and tear, changing in pressure, and or plumbing issues

First, you may hear that

·         There is a small and gentle bang when you turn off a tap

·         There is movement in the pipes sometimes

·         There are minor vibrations in the walls

When time goes on, you will hear that

·         There is hard banging in the pipes

·         There are constant sounds like hammering

·         The ventilator is making noises when the water is turned off

·         There are more leaks in the joints

Therefore in such cases, early identification leads to homeowners saving many thousands of dollars in the future.

Why Water Hammer in Pipes Is a Serious Concern

Water being hammered inside the pipes is not just an issue but it could be a killer problem in the future as well because when water is immediately stopped, there is no place to let go of all the energy that the pressure of water was carrying with it when the shockwave hits against the walls of the pipes

What would this do in the longer run?

·         Pipe joints would be cracked

·         Issues with the fittings

·         Shutoff valves will be damaged

·         Water leaks behind the walls of the homes

This pressure will ultimately reduce the life of the whole plumbing system of the home in case that you avoid professional plumbing repair services immediately.

Banging or Hammering

Regularly associated with banging of water pipes when shutting off or pressure imbalance.

Rattling

Continuous Vibrations

Pipes Making Noise When Water Is Turned Off and the Impact of Appliance Valves

Another thing which is often overlooked when the pipes making noise when water is turned off is that what is the condition of the valves of the appliances in your home. Fast closing or solenoid valves are the ones which are the ones mostly being used in newer appliances and these are efficient, so much so that they immediately stop the water which may result in it creating pressure from immediately stopping.

These valves sometimes cause water hammers in the pipes when they are closed and this may be more harmful in situations where there are no precautions taken for shock absorption. Over time, what this means is that the joints and fittings in the pipes will loosen up and the pipes will result in an ongoing banging noise.

This situation can be made worsen if the appliances are using older versions of valves. These valves sometimes not open all the way hence making changing or fluctuating pressure in the pipes. This will result in a loud noise in the plumbing system and can also happen when the appliance is shut off.

Early detection in such cases could be considered a miracle as this would save you thousands of dollars in the future.
