Customer Questions & Answers

Question:
What is a water hammer arrestor and how does it work?
Answer: A water hammer arrestor is a device designed to absorb shock waves that occur when water flow is suddenly stopped or changed direction, preventing hammering noises in your plumbing system. It works by using a diaphragm or piston sealed within an airtight chamber filled with gas. When water strikes the sudden stop, the arrestor compresses the gas, absorbing the shock and minimizing noise. This practical solution is particularly effective in residential plumbing systems, where sudden changes in water pressure can lead to rattling pipes and damage if left unchecked. -
Question:
Where can I use the Watts 34 LF15M2-B Water Hammer Arrestor?
Answer: The Watts 34 LF15M2-B Water Hammer Arrestor can be installed in various locations within your plumbing system, including near washing machines, dishwashers, and other appliances with faucets that cause water hammer. Its compact design allows for installation in tight spaces, making it ideal for residential settings. This device ensures that the flow of water remains smooth and quiet, enhancing your overall comfort and protecting your plumbing infrastructure from potential damage caused by sudden pressure changes. -
Question:
What are the benefits of installing a water hammer arrestor?
Answer: Installing a water hammer arrestor provides several benefits. First, it significantly reduces noise caused by water hammer, which is often perceived as disruptive and annoying. Additionally, it helps protect your plumbing pipes and appliances from potential damage that can occur due to the shock wave created from sudden changes in water flow. Furthermore, by maintaining a quieter and more stable water pressure, it enhances the overall efficiency of your plumbing system, which can lead to improved longevity of fixtures. -

Operating within this range ensures optimum performance, effectively mitigating the effects of water hammer. If the pressure is too low, the arrestor may not perform adequately, while excessively high pressures can lead to an increased risk of plumbing issues. For best results, regularly check the water pressure in your home and adjust accordingly to maintain peak functionality. -
Question:
Can I install the Watts 34 LF15M2-B myself, or should I hire a professional?

If you encounter complications or are unsure about the plumbing configuration, a professional can help avoid potential errors and ensure the system operates as intended. -
Question:
What materials is the Watts 34 LF15M2-B made of?

Brass is chosen for its resistance to corrosion, ensuring longevity and reliability within your plumbing system. The quality materials contribute to the overall effectiveness of the arrestor, providing robust performance even under varying pressure conditions.
