Introduction
Greetings to all our readers! In this article, we will discuss how to fix water hammer- a common plumbing issue that many homeowners face. If you hear a loud banging noise when you shut off a faucet, then you are experiencing water hammer. It is caused by a sudden stoppage of water flow through pipes, creating a shockwave that can damage your plumbing system. But the good news is, it is easy to fix. In this article, we will provide you with a complete guide on how to fix water hammer and prevent it from happening again.
The Causes of Water Hammer
Before we discuss how to fix water hammer, it is essential to understand why it occurs. Water hammer occurs when there is a sudden change in water pressure, causing a shockwave to travel through your pipes. It could be caused by several factors such as:
| Causes of Water Hammer | Explanation |
|---|---|
| High Water Pressure | When the water pressure is too high to handle, it causes water hammer |
| Loose Pipes | When pipes are not fixed securely, they tend to move, which can cause hammering |
| Fast Closing Valves | Valves that close too quickly can cause water hammer |
| Water Heater Issues | Heating water can cause it to expand, which can cause water hammer if there is nowhere for the water to go |
To fix water hammer, you need to identify the cause and apply the appropriate solution. Let’s discuss how to fix water hammer below.
How to Fix Water Hammer
1. Check Water Pressure
The first step to fix water hammer is to check the water pressure. If the pressure is too high, it can cause water hammer. Use a pressure gauge to check the pressure; it should be between 40 psi to 60 psi. If it’s higher than 60 psi, you need to lower the pressure by adjusting your pressure regulator or installing a new one.
2. Secure Loose Pipes
If you have loose pipes, they tend to move when the water flows through them, causing water hammer. To fix this, secure the pipes using clamps or straps to prevent them from moving. You may need to hire a plumber to fix this issue.
3. Install Water Hammer Arrestors
Water hammer arrestors can prevent water hammer by absorbing the shockwave created by the sudden change in water flow. You can install them at the source of the problem, such as near the washing machine, dishwasher, or shut-off valve.
4. Replace Fast Closing Valves
If your valves close too quickly, they can cause water hammer. Replace them with slow-closing valves to prevent water hammer. This may require the help of a plumber.
5. Insulate Pipes
When hot water flows through cold pipes, it can cause the pipes to expand and contract, causing water hammer. To prevent this, insulate your pipes with foam sleeves or insulation to reduce the temperature difference.
6. Drain Water Heater
If your water heater is causing water hammer, drain it to remove sediment build-up. Sediment can cause a blockage, resulting in water hammer.
7. Maintain Plumbing System
Regular maintenance of your plumbing system can prevent water hammer and other plumbing issues. Hire a plumber to inspect your pipes, valves, and appliances regularly.
