Determining the origin of the hammer effect can be difficult which makes picking the site for the hammer arrestor more complicated. The effect can be made obvious through insufficient pipe supports that allow pipes to move and vibrate loudly but this can be quite a long distance from the actual source. When hammer travels long distances it is harder to hear the onset to determine what the actuation point is and it is a matter of elimination sometimes to find the action that causes the problem.

This is easy to adjust as they are fitted with a Schrader valve as used on car tyres so it is simple to bleed some air pressure out or put more in and evaluate the changes. The smaller arrestors would require an external gauge to check the pressure but the larger ones are supplied with a pressure gauge as standard.

Pressure regulating valve

Exactly where to place the hammer arrestor will depend on the actual piping arrangement. The best places are either close to the pump, isolation or check valve that is originating the hammer, or at more distant points where the pipe changes direction, for example at the top of a pump riser. Using an angle type arrestor such as the P12 in place of a pipe elbow can be very effective at reducing transient pressure spikes from either direction. Replacing pipe elbows with a tee and fitting a P14 arrestor is also an option and this allows for maximum transient suppression when in line with the returning wave.

Water hammer is created when a valve closes or a pump stops quickly and the momentum of the water creates a pressure wave that rebounds from the closed port, travelling back up the pipe. This is exacerbated when the frequency of the transient pulse resonates with the pipework or from standing waves in the system that can build to the extent that severe damage can be caused.

A pressure regulating valve is an essential part of any home plumbing installation, protecting your pipes and appliances from pressure surges in the water or gas supply. The water pressure-reducing valve range at Ace features components suitable for both home and commercial use, with a wide range of pressure ratings, materials and end-point designs to ensure a perfect fit.

As many systems do not have the same pressure throughout, this enables adjustment of each arrestor to suit the inlet pressure conditions where each are sited. For systems with fluctuating pressures, the use of multiple arrestors that are all set to slightly different internal pressures, can effectively bracket the system pressure range so that they coordinate the effectiveness.

Regulator valves have other benefits besides the safety of maintaining a steady pressure. Turning down the valve can reduce water consumption by up to a third, helping to save money if you're on a metered connection. Lower water pressure can make heaters and boilers work more efficiently, saving on energy bills, while also reducing the amount of noise produced in your plumbing.

Pressure regulators and relief valves are closely related but not the same thing. A pressure regulating valve reduces the pressure in a mains supply to a safe level, while relief valves offer an easy way for excess pressure to escape in an emergency. Most often, surges of water pressure are directed safely into the drain system before they can damage your HVAC system or pipework.

Preventing hammer upstream of isolation valves can be achieved through fitting a hammer arrestor of either type at the last pipe bend or elbow prior to the valve inlet. Depending on the severity of the water hammer, several arrestors can be employed to reduce the impact throughout the system. One close to the pump or valve and one at the first high point or one in each of a pair of series elbows prior to a tall riser.

The P12 and P14 water hammer arrestors are supplied already pressurised from the factory and can be installed and used without further adjustment. However, to get the most efficiency from them, they work best when pressurised at 30 to 50% of the normal working pressure.

Water in an urban area is typically supplied at a high pressure to ensure it can reach into tall buildings, remote areas, and other difficult destinations. In many cases, the pressure is higher than the typical maximum ratings of pipes, heaters, and other parts of a plumbing installation, which can risk leaks and other damage.

What’s more, fitting a pressure regulating valve at the lower level of a building leaves plenty of pressure in reserve to help the water reach the higher floors, which is important in multi-occupant buildings.

To ensure your pressure relief valve can withstand the everyday pressures of your water system, it's important to choose the right maximum pressure rating. Our range includes PSI ratings for small and large applications, providing a valve option for every installation.

To round out our valves and plumbing department, we also carry a wide range of other valve types to suit different areas of your installation, including:

Simply choose date & time option(s) that fit your schedule. Rest assured, we'll call to confirm.

What's more, the water pressure isn't always consistent and can rise and fall depending on how much water is being used across an area. A water pressure-reducing valve solves both these problems by keeping the water at a safe and constant pressure that's within your plumbing system's ideal range.
