There are some irritating sounds that can be heard, especially when things have quieted down, such as noises created by water hammer. Water hammer sounds are a concurring pressure shocks that gets formed when there is an abrupt alterations to the speed of liquid, particularly water, in pipes. The presence of water hammer is also an indication that your water pipe system either needs repair of replacement. Below are the materials that you need along with the instructions on how to eliminate water hammer.

Step 1-Design for the Water Piping System

Your water piping system must be designed in such a way that the existence of water hammer is avoided. The speed of liquids, particularly water, must be below 5 fps so as to avoid water hammer. Consult your local building code on how a water piping system should be designed and installed in your home or building.

Step 2-Replacement of Pipes

Large piping is necessary to lower the flow velocity of water. If you find that your water pipes are small, replace your small water pipes with bigger water pipes using an adjustable wrench to remove water hammer. Wear a good pair of working gloves while doing this step.

Step 3-Insulating the Pipes

If you have access to your water pipe, insulate the water pipe where you suspect the water hammer is coming from by wrapping the water pipe with an old towel or shirt. Wrapping your water pipe in cloth will minimize the rattling of your water pipes.

Step 4-Clearing Air Chambers of Water

For those fluid pipes that have air chambers packed with water in their plumbing system, this problem should be corrected by simply shutting off the main water valve. The faucets located indoor and outdoor should be opened and have water run through to drain. Clearing the air chamber with water will allow the flow of water to circumvent in the air chambers, filling it up with air. It is a good idea to have air chambers installed in the plumbing system if it does not have one installed.

Step 5-Installation of a Water Hammer Eliminator

If the rattling sounds still are not eliminated, consider the installation of a water hammer eliminator. This gadget performs like a shock absorber or air chamber, which could be installed to the existing plumbing system.

Step 6-Make Valve Adjustments

When needed, make adjustments on the valve used at points where an abrupt altercation occurs in water velocity. Determine the kind of valve to use that will minimize water hammer. There are instances when a form of control can be placed by the exhaust vent in order to eliminate rattling sounds.

Step 7-Install a Desurger

If necessary, build a stand pipe for each valve from the existing pipes coming from the main line. One attributing factor leading to water hammer is when a water pump starts and stops suddenly. To solve this problem, install a desurger in your water system. A desurger is a tank-like basin installed at the end of your water pump.
