In some cases, it may be necessary to install multiple WHAs throughout the plumbing system to effectively control the water hammer. It's important to consult with a licensed plumber to determine the appropriate location for installation and the number of WHAs required based on the specific plumbing configuration and water pressure.

A Pressure Vacuum Breaker (PVB) is a type of backflow preventer. It allows the water from your supply to go through and flow into your valves which in turn, irrigates your lawn. However, if your device isn’t properly winterized water can get stuck. As we all know, when water freezes it expands and as a result of the expansion, this particular piece can actually fracture.

When it comes to choosing the right water hammer arrestor, there are a few key factors to keep in mind. Firstly, it’s important to consider the size and pressure rating of the arrestor. This will ensure that the arrestor can handle the specific needs of your plumbing system and prevent unwanted noise and damage from water hammer.

A WHA typically consists of a sealed cylinder that contains a spring-loaded piston or air bladder. When the water flow is suddenly stopped, the pressure wave is absorbed by the piston or bladder, which compresses the air inside the cylinder. This helps absorb the shock and prevents the pressure from building up and causing water hammer. WHAs are commonly used in residential and commercial plumbing systems, particularly in areas where water pressure is high or where the pipes in your piping system are long or complex.

In some cases, it may be necessary to install multiple WHAs throughout the plumbing system to effectively control the water hammer. It’s important to consult with a licensed plumber to determine the appropriate location for installation and the number of WHAs required based on the specific plumbing configuration and water pressure.

Additionally, it’s important to note that WHAs need to be checked and maintained sometimes to ensure proper functioning. Over time, the air inside the cylinder may leak or become depleted, which can reduce the effectiveness of the WHA. It’s recommended to have a licensed plumber check and replace the WHAs every 5-10 years, depending on usage and other factors.

The model in this example is the 765 and the manufacturer is Febco. The number behind the dash indicates the size of the particular PVB. The Febco poppet bonnet assembly kit used in this demonstration contains the bonnet, poppet, and some lubricant or grease to aid in the repair process.

A Water Hammer Arrestor should always be installed so the shock dead-ends into the arrestor. Arrestors should always be placed as near to the source of shock as possible.

What is a Water Hammer Arrestor (WHA)? A water hammer arrestor (WHA) is a device installed in a plumbing system to prevent the sound of water hammer – that loud banging noise that can occur when water flow in your water line is suddenly stopped by a closing valve. This noise is caused by a pressure wave that travels through the pipes when the flow in your water supply is stopped abruptly, and can cause damage to pipes, fittings, and appliances.

This will ensure that the arrestor can handle the specific needs of your plumbing system and prevent unwanted noise and damage from water hammer. Additionally, the material of the arrestor plays an important role in its effectiveness and durability. Copper and brass are common materials used in water hammer arrestors, as they are both resistant to corrosion and able to withstand high pressure. Lastly, proper installation is crucial for ensuring the effectiveness of the water hammer arrestor. It's recommended to have a licensed plumber install the arrestor to ensure that it is done correctly. Where to Install a Water Hammer Arrestor?

Flush line prior to installation. Use thread tape to seal pipe threads. To tighten, place the wrench on hex only. For best results, match Arrestor to pipe size at the point of installation. Vertical or horizontal installations are acceptable. Verify recommended pressure rating. ** Parts ordered may look slightly different than the picture displayed, but the fit and function will be the same.
