Are Banging Pipes and Hydraulic Shock Damaging Your Facility’s Plumbing System?
Air, bubbles, and turbulence in your water line cause your meter to register more than you actually use. The Flow Conditioning Device (FCD) corrects that — installed after your meter in about an hour, with negligible pressure loss and no change to your operations.

pressure loss — nothing changes operationally
Direct answer: Water hammer is a pressure shockwave caused by a sudden change in water velocity inside a pressurized piping system — typically from a fast-closing valve or an abrupt pump shutdown. Left unaddressed, it destroys valves and fittings, loosens joints, damages pumps, and can cause sudden pipe failure. The right fix depends on the cause and usually combines two or more approaches: correctly sized and positioned water hammer arrestors, slow-close valves, pressure reducing valves, surge suppression, system redesign, or flow conditioning at the point of service entry. A proper diagnosis resolves the causes present in your system today — installing new equipment or modifying piping later can change the system's pressure and flow dynamics enough to reintroduce the problem, so a treated system is worth re-evaluating after any significant change.
Does This Sound Like Your Facility?
Water hammer is often dismissed as a nuisance rather than treated as a serious mechanical problem. But those bangs and shudders are pressure spikes that can reach many times your system’s working pressure — and they happen every time a valve closes or a pump shuts off. Here are the signs your facility has a water hammer problem right now.
You hear loud banging in your pipes
A sharp bang, thud, or clang every time a valve closes or a pump shuts off — sometimes loud enough to be heard throughout the building or facility.
Your pipes shake or vibrate
Visible pipe movement, shaking fittings, or rattling pipe supports — especially in long straight runs where pressure waves have room to build.
You’re replacing valves and fittings too often
Repeated shock loads loosen threaded joints, crack fittings, and destroy valve seats far ahead of their normal service life.
You’re getting recurring leaks at joints
Water hammer gradually works threaded and flanged connections loose — causing leaks that keep coming back even after repair.
Your pumps are failing prematurely
Hydraulic shock waves travel back through the system to your pumps, damaging impellers, mechanical seals, and bearings over time.
You’re getting noise complaints
In commercial buildings, hotels, apartments, and healthcare facilities, pipe banging generates tenant and patient complaints that are difficult to explain away.
What Is Water Hammer Actually Costing Your Facility?
Most facilities treat water hammer as a maintenance issue and keep repairing the damage without addressing the cause. When you add up the full cost — parts, labor, downtime, and emergency repairs — the number is almost always much higher than the cost of fixing the problem at the source.
🔧
Valve & Fitting Replacement
Repeated shock loads destroy valve seats, crack fittings, and loosen joints — driving up parts and labor costs year after year.
⚙️
Pump Repairs & Replacement
Hydraulic shock that reaches your pumps causes impeller damage, seal failure, and bearing wear that shortens equipment life significantly.
💧
Leak Repairs & Water Damage
Joints loosened by water hammer eventually leak — and in a commercial or industrial setting, water damage from a burst pipe can be catastrophic.
⏱️
Unplanned Downtime
Emergency pipe repairs and production stoppages caused by water hammer failures cost far more than the repair itself — in lost time, output, and disruption.
📋
Compliance & Liability Risk
In healthcare and food processing, a piping failure triggered by water hammer can mean regulatory action, contamination risk, or facility shutdown.
Why Is Water Hammer Happening in Your System?
Water hammer is caused by sudden changes in water velocity inside pressurized pipes. When moving water is forced to stop or change direction quickly, the kinetic energy has nowhere to go — it converts instantly into a pressure spike that slams through the entire piping system. Here are the most common causes in industrial and commercial facilities.
Fast-Closing Valves
Solenoid valves, quick-acting ball valves, and electrically actuated valves that close in under one second are the most common cause of severe water hammer in industrial systems.
Pump Start & Stop
When a pump starts or stops suddenly, it creates a pressure wave in both directions through the connected piping — especially in long pipe runs with no surge protection.
High System Pressure
The higher your operating pressure, the more severe the water hammer shockwave when flow is interrupted. High-rise buildings and industrial systems are particularly vulnerable.
Long Straight Pipe Runs
Pressure waves travel faster and with more force in long, straight pipe runs with few bends or branches to dissipate the energy.
Undersized or Missing Arrestors
Water hammer arrestors that are undersized, incorrectly located, or waterlogged provide little or no protection — leaving the system unprotected despite the appearance of a solution.
Air in the System
Air pockets in pressurized water lines act as compressible cushions that can amplify pressure spikes rather than absorb them when water hammer occurs.
What Are Your Options for Fixing It?
The right solution depends on what’s causing the water hammer in your specific system. A single approach rarely solves the problem completely — effective water hammer control usually combines two or more of the following strategies.
Direct answer: A properly diagnosed fix resolves water hammer caused by your system's current configuration. If new equipment is installed, valves are changed, or piping is modified later, the system's pressure and flow dynamics can change too — sometimes reintroducing water hammer even after a successful fix. Any significant change to a treated system is worth a follow-up look.
Water Hammer Arrestors
Correctly sized and positioned arrestors absorb the pressure spike at the source before it travels through the system. Most facilities with water hammer problems have either no arrestors or undersized ones in the wrong locations.
Slow-Close Valves
Replacing fast-acting valves with slow-closing alternatives extends the valve closure time beyond the critical threshold — allowing the water column to decelerate gradually rather than stop suddenly.
Pressure Reducing Valves
Reducing system operating pressure directly reduces the severity of water hammer shockwaves. A properly sized PRV can significantly cut peak pressure spikes throughout the downstream system.
Surge Suppression Systems
For large industrial systems, pump stations, and municipal water distribution, engineered surge suppression — including surge tanks, air vessels, and controlled valve timing — addresses water hammer at the system level.
System Redesign
In some cases the piping layout itself — long unsupported runs, missing expansion loops, or inadequate pipe anchoring — amplifies water hammer beyond what any single device can manage. A system redesign addresses the root cause.
Flow Conditioning
Controlling the velocity and pressure profile of water as it enters your facility can reduce the energy available to create water hammer events in the first place — addressing the problem upstream rather than treating the symptoms.

We identify exactly what is generating the water hammer — not just where you hear it, but where the pressure spike originates.
3
Solution Specification
We recommend the right combination of devices and system changes to eliminate the problem at the source.
4
Implementation Support
We support your team or contractor through installation and confirm the fix addresses the source rather than just masking symptoms.
