How to Repair Noisy Pipes in the Home’s Plumbing Lines

Are you hearing an odd thumping noise when turning off water faucets?

Water movements on closed valves

Many of have experienced that odd banging noise when using a water faucet, and it’s easy to write off as just a quirk of the valves when it’s definitely NOT! This common system noise might lie at the heart of several pressure problems that can cause greater damage. The noise itself, commonly called Water Hammer, is the result of pressure shock in your plumbing lines that can be heard when you shut off a water faucet after it has been open and water was flowing strong.

What is Water Hammer?

Water hammer or hydraulic shock phenomenon and can be understood as abrupt collision of fast moving solid slug with in the piping system with any obstruction that may be bend, valve etc. Thus Water hammer is defined as a sudden increase in pressure on account of hindrance to fluid motion or direction-change. Read more…

Water Hammer Information

Water hammer can be a big thump that shakes the house, or a series of banging noises starting with a loud bang followed by several “echoes”. Rapidly closing or opening a valve causes pressure transients in pipelines. Sources of water hammer lies on three factors such as length of the pipe the water is traveling through, how fast the water is being stopped and the velocity of the water.

The most effective means of controlling water hammer is a measured, compressible cushion of air which is permanently separated from the water system.When the valve closes and the water flow is suddenly stopped, the pressure spike pushes the piston up the arrester chamber against the pressurized cushion of air. The air cushion in the arrester reacts instantly, absorbing the pressure spike that causes water hammer. Click here to read more.

For homeowners with time on their hands, your natural inclination is to consider some DIY, so we grabbed some great, helpful advice for you from How Stuff Works: Home & Garden put together a simple solution to stop water hammering within your pipe lines.

How To Stop Water Hammer

If you never had hammering and then it suddenly starts, most likely your plumbing system’s air chambers have become waterlogged. You can cure water hammer by turning off the water behind the waterlogged chamber, opening the offending faucet and permitting the faucet to drain thoroughly. Once all the water drains from the chamber, air will fill it again and restore the cushion. If the air chamber is located below the outlet, you may have to drain the main supply lines to allow the chamber to fill with air again.

What do you do if there are no air chambers built into your plumbing system? You must do something, because water hammer pressures may eventually cause damage: failure of fittings or burst pipes, for example. Because water hammer is most often caused by water pressure that’s too high, the first step is to reduce the water pressure if possible. Sometimes this isn’t feasible because a reduction in pressure may result in only a dribble of water at an upper-floor faucet if one on the first floor is turned on.
