No, a sound is of course not dangerous—but what it represents can definitely have a heavy negative influence on your pipes. The effect of the shockwaves can damage the pipes and knock them loose, and also damage taps, faucets, and appliances. Enough force from water hammer can even cause pipes to burst.
The noise produced is irritating and frustrating. However, that isn't the main issue. A water hammer is a surefire sign that damage may occur in your plumbing pipes. Therefore, you should enlist a plumber to inspect the plumbing system should you hear of any water hammer before permanent and costly damage arises.
The long-term effects of water hammer might present themselves in the following ways: Leaks: Water hammer has the potential to damage joints, fittings and connections, resulting in poor seals and ultimately leaky pipes.
Left untreated, water hammer can lead to actual damage to pipework, appliances and components of any system. Over time this damage can accumulate and result in the premature failure of parts of the plumbing system and all the watery hassle that can cause.
A water hammer arrestor costs from $15 to $50. They're available online, at home centers, and in hardware stores. Most of the cost of a water hammer arrestor installation is in the labor. Calling in a pro will typically run $250 – $500.
Water pipes should be quiet, so what in the world can it be? Well, it is most likely you have a water hammer. In that case, you will need to contact a local plumber to fix it. Water hammer is also referred to as hydraulic shock.
Water hammer rarely goes away on its own; it's a serious plumbing problem you should address. Pipes can sustain damage from repeated impact, resulting in leaks or burst pipes. Fixtures like faucets and valves can also be affected by water hammer stress, leading to wear and tear or even failure over time.
You can fix the problem by tightening the screws holding loose pipe straps. Additional straps can be added to improve stability. Pipe straps are usually made of thin metal or plastic, while padded types are available to reduce vibration.

But our best advice is to always fit a potable water expansion vessel on the pipework. The expansion vessel can deal with higher water pressure and you can avoid banging noises. Fit a pressure-reducing valve. Use pipe insulation around the pipes which can absorb the water hammer and pipe expansion.
In severe cases of hydraulic shock pipes can rupture and cause water damage, or possibly flooding, inside your property. If the banging noise in your pipes has increased over time it means that vibrations have increased. An increase in vibrations will also increased the likelihood of rupture.

Water hammer can cause severe damage to your water heater. With enough force and pressure, it can cause burst pipes, collapse a flue tube, cause the heater's shell to expand or even deform the top of the heating tank.

The Risks of Ignoring Water Hammer
Over time, the repeated pressure surges can weaken joints and cause leaks, or in severe cases, even cause pipes to burst. This damage can be costly to repair and may lead to water damage in your home.
Most often, the problem is a failed gasket in the pressure-reducing valve where water comes into the house. Replacing this valve, including the part and labor, costs less than $300, according to Connie Hodges, operations manager at Wacker Plumbing & Remodeling in Sterling (703-450-5565, www.wackerplumbing.com).
Water hammer can occur when an open valve suddenly closes, causing the water to slam into it, or when a pump suddenly shuts down and the flow reverses direction back to the pump.
Fixing the problem can be as easy as shutting off the main valve and draining your plumbing system. If that doesn't work, installing an arrestor or adding pipe straps and insulation can make a big difference.
Remember, installing the arrestor as close as possible to the noise-making fixture is crucial to combat the water hammer effectively. Once installed, the arrestor needs no maintenance. If you still hear a banging noise, check to see if enough straps are holding the pipes in place. If not, add more.
