Greetings, dear readers! Are you tired of hearing loud banging or clanking noises whenever you turn off your water supply? Are you worried about the potential damage that water hammer can cause to your plumbing system? If so, then you have come to the right place! In this article, we will provide you with a comprehensive guide on how to prevent water hammer and keep your plumbing system in top condition.
Introduction
Water hammer is a common problem that occurs in plumbing systems, especially in older homes. It is caused by the sudden stoppage or change in the flow of water, which creates a shockwave that travels through the pipes and creates a loud noise. If left untreated, water hammer can cause damage to your pipes, valves, and appliances and can lead to leaks or even burst pipes. Fortunately, there are several ways to prevent water hammer, and we will discuss them in detail below.
The Science behind Water Hammer
Before we dive into the solutions, it’s essential to understand the science behind water hammer. When water flows through a pipe, it creates momentum and energy. When the flow is stopped suddenly, the water’s energy has nowhere to go and creates a shockwave that travels through the pipes. This shockwave can cause vibrations, noise, and damage to the pipes and other components of the plumbing system.
Causes of Water Hammer
Several factors can cause water hammer, including:
| Causes | Solutions |
|---|---|
| High water pressure | Install a pressure reducing valve or regulator |
| Loose or worn out pipes | Tighten loose pipes or replace worn-out ones |
| Waterlogged air chambers | Drain the air chambers or install new ones |
| Malfunctioning valves | Replace faulty valves or install new ones |
The Importance of Preventing Water Hammer
Preventing water hammer is essential for several reasons:
- It reduces noise pollution
- It prevents damage to your pipes, valves, and appliances
- It increases the lifespan of your plumbing system
- It saves on water and energy costs
How to Prevent Water Hammer
Now that we’ve covered the basics let’s dive into the solutions on how to prevent water hammer:
Solutions for Preventing Water Hammer
1. Install a Pressure Reducing Valve or Regulator
High water pressure is one of the most common causes of water hammer. If your water pressure is above 80 psi, it can cause damage to your plumbing system and create water hammer. Installing a pressure reducing valve or regulator can help regulate the water pressure and prevent water hammer.
2. Tighten Loose Pipes or Replace Worn-Out Ones
Loose or worn-out pipes can also cause water hammer. If you notice any loose pipes, tighten them immediately. If the pipes are worn-out, replace them as soon as possible.
3. Drain the Air Chambers or Install New Ones
Waterlogged air chambers can also cause water hammer. Air chambers are vertical pipes that are installed in the plumbing system to absorb shockwaves caused by sudden changes in the flow of water. Over time, these air chambers can become waterlogged, which reduces their effectiveness. To drain the air chambers, turn off the water supply and open all the faucets. Once the water stops flowing, turn off the faucets and turn on the main water supply. If the air chambers are too old or damaged, it’s best to install new ones.
4. Replace Faulty Valves or Install New Ones
Malfunctioning valves can also cause water hammer. If you notice any faulty valves, replace them immediately. It’s also a good idea to install new valves that are designed to prevent water hammer.
5. Install Water Hammer Arrestors
Water hammer arrestors are devices that are installed in the plumbing system to absorb shockwaves caused by water hammer. They work by compressing air or spring-loaded pistons to absorb the shockwaves. Installing water hammer arrestors can help prevent water hammer and protect your plumbing system from damage.
6. Use Water Hammer Arrestor Washing Machine Hoses
Washing machines are one of the most common sources of water hammer. Using water hammer arrestor washing machine hoses can help prevent water hammer and protect your plumbing system from damage. These hoses contain water hammer arrestors that absorb the shockwaves caused by the washing machine’s sudden changes in water flow.
7. Regularly Maintain Your Plumbing System
Maintaining your plumbing system regularly is essential for preventing water hammer and other plumbing problems. Regular maintenance includes checking for leaks, replacing worn-out pipes, valves, and appliances, and cleaning out clogs or blockages. It’s also a good idea to hire a professional plumber to inspect your plumbing system regularly and make any necessary repairs or upgrades.
Advantages and Disadvantages of Preventing Water Hammer
Advantages
Preventing water hammer has several advantages, including:
- Reduced noise pollution
- Increased lifespan of your plumbing system
- Reduced risk of leaks or burst pipes
- Saves on water and energy costs
Disadvantages
Preventing water hammer also has a few disadvantages, including:
- Higher upfront costs to install new devices or components
- Regular maintenance is required to keep the plumbing system in top condition
FAQs about Preventing Water Hammer
1. What is water hammer?
Water hammer is a common problem that occurs in plumbing systems when the flow of water is stopped suddenly, creating a shockwave that travels through the pipes, causing noise and potential damage to the plumbing system.
2. What causes water hammer?
Water hammer can be caused by several factors, including high water pressure, loose or worn-out pipes, waterlogged air chambers, and malfunctioning valves.
3. How can I prevent water hammer?
You can prevent water hammer by installing a pressure reducing valve, tightening loose pipes, draining the air chambers or installing new ones, replacing faulty valves, using water hammer arrestors, and regularly maintaining your plumbing system.
4. How do water hammer arrestors work?
Water hammer arrestors work by absorbing shockwaves caused by sudden changes in water flow. They contain air or spring-loaded pistons that compress when the water flow is stopped suddenly, reducing the impact of the shockwave.
5. Can water hammer cause damage to my plumbing system?
Yes, if left untreated, water hammer can cause damage to your pipes, valves, and appliances and can lead to leaks or even burst pipes.
6. How much does it cost to install a pressure reducing valve?
The cost of installing a pressure reducing valve varies depending on the type and size of the valve. On average, it can cost between $100-$500.
7. How often should I maintain my plumbing system?
You should maintain your plumbing system at least once a year. Regular maintenance includes checking for leaks, replacing worn-out pipes, valves, and appliances, and cleaning out clogs or blockages.
8. Can I install water hammer arrestors myself?
You can install water hammer arrestors yourself, but it’s recommended to hire a professional plumber to ensure that it’s installed correctly.
9. What is the lifespan of water hammer arrestors?
The lifespan of water hammer arrestors varies depending on the type and quality of the device. Most water hammer arrestors last between 5-10 years.
10. Can I use regular washing machine hoses?
Using regular washing machine hoses can cause water hammer. It’s recommended to use water hammer arrestor washing machine hoses to prevent water hammer and protect your plumbing system.
11. Can I prevent water hammer by turning off the water supply slowly?
No, turning off the water supply slowly can reduce the impact of the shockwave, but it won’t prevent water hammer from occurring.
12. How can I tell if I have water hammer in my plumbing system?
You can tell if you have water hammer in your plumbing system if you hear loud banging or clanking noises when you turn off the water supply.
