Water Storage Tank Noise: The Ultimate Explanation and Solution
What To Know
- If there’s already air in the tank, you can bleed it out by opening the drain valve at the bottom of the tank and allowing water to flow out until the air is released.
- A water hammer arrester is a device that absorbs the shock of water hammer and prevents it from causing noise.
- If the float switch is faulty or malfunctioning, it can create a clicking or buzzing sound as it tries to adjust the water level.
Do you find yourself wondering, “Why is my water storage tank making noise?” If so, you’re not alone. Noisy water storage tanks can be a common issue, but don’t worry – there are usually simple explanations and solutions. In this in-depth guide, we’ll explore the various reasons why your water storage tank might be making noise, and provide you with practical tips on how to address each issue.
Air in the Water Tank
One of the most common causes of water tank noise is air trapped inside the tank. As water enters the tank, it can carry air bubbles with it. These bubbles can accumulate and create a knocking or banging sound as they rise to the top of the tank.
Solutions:
- Install an air release valve: An air release valve allows air to escape from the tank as it fills. This can help prevent air from accumulating and causing noise.
- Bleed the water tank: If there’s already air in the tank, you can bleed it out by opening the drain valve at the bottom of the tank and allowing water to flow out until the air is released.
Loose Components
Another potential source of water tank noise is loose components, such as the float valve or the inlet pipe. If these components are not properly tightened, they can vibrate and create noise as water flows through the tank.
Solutions:
- Check and tighten all connections: Use a wrench to tighten any loose bolts or screws on the float valve, inlet pipe, and other components.
- Replace worn components: If the components are old or damaged, they may need to be replaced to eliminate noise.
Water Hammer
Water hammer occurs when water suddenly stops or changes direction in a pipe. This can create a loud banging or hammering sound. Water hammer can be caused by a variety of factors, including:
- Closing faucets or valves too quickly
- Faulty appliances (e.g., dishwashers, washing machines)
- Incorrectly sized pipes
Solutions:
- Install a water hammer arrester: A water hammer arrester is a device that absorbs the shock of water hammer and prevents it from causing noise.
- Adjust the closing speed of faucets and valves: Closing faucets and valves more slowly can help reduce water hammer.
- Call a plumber: If you suspect that your water hammer is caused by a plumbing issue, it’s best to call a licensed plumber for assistance.
Pressure Relief Valve Problems
The pressure relief valve on your water storage tank is designed to release excess water pressure. If the pressure relief valve is faulty or malfunctioning, it can create a hissing or whistling sound.
Solutions:
- Test the pressure relief valve: Open the valve and check if water flows out. If water does not flow, the valve may be clogged or faulty and needs to be replaced.
- Replace the pressure relief valve: If the valve is damaged or worn, it should be replaced with a new one of the same size and type.
Corroded Pipes or Tank
Over time, pipes and water storage tanks can become corroded. This can lead to leaks, which can create noise as water drips or sprays.
Solutions:
- Inspect pipes and tank for leaks: Check for any visible leaks or signs of corrosion on the pipes and tank.
- Repair or replace corroded components: If you find any leaks or corrosion, you can either repair them yourself or hire a plumber to do the job.
Faulty Float Switch
The float switch in your water storage tank is responsible for controlling the water level. If the float switch is faulty or malfunctioning, it can create a clicking or buzzing sound as it tries to adjust the water level.
Solutions:
- Inspect the float switch: Check the float switch for any visible damage or debris.
- Replace the float switch: If the float switch is damaged or faulty, it should be replaced with a new one.
Other Potential Causes
In some cases, water storage tank noise can be caused by other factors, such as:
- Sediment buildup: Sediment can accumulate in the tank and create noise as water flows through it.
- Faulty pump: A faulty pump can create noise as it tries to circulate water.
- External vibrations: Vibrations from nearby appliances or machinery can transmit to the water storage tank and create noise.
Summary: Resolving Water Storage Tank Noise
By understanding the various causes of water storage tank noise and implementing the appropriate solutions, you can effectively eliminate the issue and enjoy a quiet and trouble-free water system. Remember to regularly inspect and maintain your water storage tank to prevent noise problems from recurring.
