About Water Hammer Repair in Strand

Water hammer is that loud banging or thudding noise in your pipes that occurs when taps, washing machines, or dishwashers shut off quickly. It is caused by a sudden pressure shockwave travelling through your plumbing system, and while it is alarming to hear, the real concern is the damage it causes over time. Repeated water hammer can loosen pipe joints, crack soldered connections, damage valves, and even burst pipes.

At Abacas Solution, we diagnose the specific cause of water hammer in your Strand home and apply the right fix. The most common cause is excessive water pressure combined with fast-closing solenoid valves in appliances like washing machines and dishwashers. When a solenoid valve snaps shut, it creates a shockwave that travels through your entire pipe system at the speed of sound.

Our solutions include installing water hammer arrestors at the point of impact, adjusting or installing a PRV to reduce incoming pressure, securing loose pipes that rattle against framing, and replacing worn air chambers that have become waterlogged. We also check for high-pressure conditions that make water hammer worse. In many Strand homes, simply reducing the incoming water pressure with a properly adjusted PRV eliminates the problem entirely. We diagnose before we recommend, so you only pay for the fix you actually need.

This is one of several specialist services we offer under water systems & pressure in Strand. As part of our Strand plumbing team, we bring over 25 years of hands-on experience to every job.

When to Call for Water Hammer Repair

Call us if you hear banging, thudding, or rattling in your pipes when taps close, when the washing machine or dishwasher cycles, when a toilet cistern fills, or when any fixture turns off suddenly. Also call if pipes vibrate noticeably or if you have noticed any new leaks at joints, as these may be caused by water hammer damage.

Our Water Hammer Repair Process

1

Noise Diagnosis

We identify exactly where and when the water hammer occurs, testing different fixtures and appliances to locate the source.

2

Pressure Check

We test your water pressure as excessive pressure is the most common underlying cause of water hammer in residential properties.

3

Targeted Fix

We install water hammer arrestors, adjust or install a PRV, secure loose pipes, or replace waterlogged air chambers as needed.

4

Verification

We run the offending fixtures and appliances multiple times to confirm the water hammer is eliminated before completing the job.

Many homeowners in Strand who need water hammer repair also require water pressure problems in Strand and prv installation. We handle everything, so you only need one call.

Safety & Compliance

Water hammer creates pressure spikes that can exceed the rated pressure of plumbing components, leading to joint failures and burst pipes. Homes with pressure above 400 kPa are at higher risk and should have a functioning PRV installed. Persistent water hammer should be addressed promptly before it causes pipe or fitting failures.

Frequently Asked Questions

Why do my pipes bang when the washing machine fills in Strand?

Washing machines and dishwashers use solenoid valves that open and close almost instantly. When these valves snap shut, they create a pressure shockwave (water hammer) that travels through your pipes. The banging is the shockwave hitting pipe bends, joints, and fixtures. High water pressure makes this worse. We fix it by installing arrestors near the appliance and reducing system pressure if needed.

Can water hammer damage my plumbing in Strand?

Yes, absolutely. Each water hammer event creates a pressure spike that stresses pipe joints, soldered connections, and valve seats. Over months and years, this repeated stress can crack solder joints, loosen compression fittings, damage tap internals, and in severe cases burst pipes. It also accelerates wear on appliance valves and connections. Fixing water hammer is preventative maintenance that avoids expensive repairs.

What is a water hammer arrestor?

A water hammer arrestor is a small device installed in the water line near the source of the problem. It contains a sealed air chamber or piston that absorbs the pressure shockwave when a valve closes suddenly. Unlike old-style air chambers that can become waterlogged, modern arrestors are sealed and maintenance-free. We install them at the specific point where hammer occurs for maximum effectiveness.

Will reducing my water pressure stop the banging pipes?

In many cases, yes. High municipal pressure is the single biggest contributor to water hammer in Strand homes. Reducing pressure from 500+ kPa down to 300-350 kPa with a PRV often eliminates water hammer entirely. If it persists at lower pressure, we add arrestors at the specific fixtures causing problems. We always check pressure first as it is the most cost-effective starting point.
