15mm Shock Arrestor Compression Fitting | Stop Water Hammer

15mm Shock Arrestor Compression Fitting

Stop Water Hammer Before It Damages Your Plumbing System

Loud banging pipes can quickly become more than just an annoyance. Water hammer creates sudden pressure surges that travel through your pipework whenever water flow stops abruptly. Over time, these repeated shocks can place unnecessary strain on valves, fittings and connected appliances.

The 15mm Shock Arrestor Compression Fitting provides a simple and effective solution. It absorbs pressure surges before they travel through your plumbing system, helping to reduce pipe noise and protect your installation from unnecessary wear.

Its compact design allows you to install it easily on 15mm pipework using a standard compression connection. As a result, you can fit the arrestor quickly without specialist tools or complicated modifications. This makes it an excellent choice for new installations, system upgrades and repairs.

The shock arrestor works particularly well on appliances that use fast-closing valves, including washing machines, dishwashers, toilets and some mixer taps. These appliances often create the sudden pressure changes responsible for water hammer. By absorbing these surges, the arrestor helps create quieter pipework while reducing stress on your plumbing system.

Manufactured from durable brass, the fitting offers long-lasting performance in domestic and light commercial plumbing systems. Whether you are solving an existing water hammer problem or protecting a new installation, this 15mm Shock Arrestor Compression Fitting delivers a reliable and cost-effective solution.

THE PROBLEM IT SOLVES

Water hammer occurs when flowing water stops suddenly. The pressure wave travels through your pipework and creates loud banging or knocking noises. If left untreated, repeated pressure surges can place additional stress on valves, joints and connected appliances.

Installing a 15mm Shock Arrestor Compression Fitting absorbs these pressure spikes before they reach the rest of your plumbing system. As a result, your pipework runs more quietly while the risk of long-term damage reduces.

WHY CHOOSE THIS PRODUCT?

Choosing the correct shock arrestor protects both your plumbing system and your appliances.

This compact compression fitting installs quickly and immediately begins reducing damaging pressure surges. It also helps minimise vibration, reduce pipe noise and improve the overall reliability of your installation.

Instead of simply masking the symptoms of water hammer, it addresses the cause by absorbing the pressure surge before it can travel through the system.

WHEN SHOULD I USE THIS PRODUCT?

Install a shock arrestor whenever you notice banging pipes after a tap, washing machine or dishwasher switches off.

It also makes sense to install one during new plumbing work. Preventing water hammer from the start helps protect pipework and appliances from unnecessary wear.
