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.
From the preceding, it can be noted that a water hammer is harmful. Hence, whenever you notice it, you should have a plumber come over and fix the issue.
While water hammers initially start out as just loud noises inside your pipes, they can cause serious damage to your plumbing if they aren't fixed soon after the problem begins.
The trouble is that the noise isn't just irritating. Water hammer is a key sign that damage may be occurring in your plumbing system. Problems with your plumbing and central heating system can be a nightmare. You must fix the cause of water hammer before it results in permanent damage.
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.
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.
Water hammer is usually caused in high pressure (e.g. mains pressure) water systems either when a tap is turned off quickly, or by fast-acting solenoid valves, which suddenly stop the water moving through the pipes and sets up a shock wave through the water, causing the pipes to vibrate and 'shudder'.
Q: How long will the Sioux Chief engineered water hammer arresters last? A: Although arresters are typically tested to 10,000 cycles, Sioux Chief arresters have been independently lab tested to withstand 500,000 cycles without failure.
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. If you hear rattling sounds along with the water hammer, it likely means you have pipes coming loose.
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 only solution is to drain the entire system to "recharge" the air chamber. A more practical and enduring solution is using water hammer arrestors.

With a varitey of issues contributing to the problem, only a qualified plumber will be able to accurately identify and address water hammer effectively. To be able to do this they'll have to inspect your homes plumbing system and determine the exact source of the problem before taking appropriate action to resolve it.
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.
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.
Ignoring water hammer can ultimately result in the catastrophic failure of your flow system. The long-term effects of water hammer can include: Pump and Flow System Damage.
Loose mounting straps contribute to water hammer. Check your accessible pipes to ensure they're secured in a way that allows some movement but doesn't let the pipes shake forcefully. If you hear the hammering noise only after shutting off a particular faucet, the cause is likely to be a worn-out faucet washer.
When this happens, the cause is usually that water has bubbled up into the air chamber over time, nullifying its protective effects. But fixing this is relatively easy: shut off the home's main water valve and then open faucets at the highest and lowest points of the structure.
Also called a hydraulic surge or a hydraulic shock, the water hammer effect usually happens when moving fluids are forced to change directions or are stopped abruptly. The term water hammer sounds alarming, but it' not a plumbing emergency. However, it could be an indication of the current condition of your pipes.
Open one or two faucets before turning the water back on, then incrementally restore water until you see it freely flowing out of the open fixture. When turning the water back on after a shut-off, turn the water-cutoff valve counter-clockwise slowly (and extra slow for lever handles) to return the water supply.
