To help our customers solve common issues with brass valves, we at BORNIC have put together this straightforward guide. A spitty or hissing sound from a valve can be annoying and sometimes confusing, but don’t worry—it’s usually an easy fix. Whether the problem is caused by air in the pipes, high water pressure, or a worn valve, this guide will walk you through the process step by step.
Step 1: Understand Why the Valve Is Making Noise
The first step in solving the problem is figuring out what’s causing the sound. Here are the most common reasons:
- Air Trapped in the Pipes: When air bubbles pass through the valve, they create that spitty or hissing noise.
- High Water Pressure: Excessive water pressure can lead to turbulence, resulting in noise.
- Damaged or Worn Parts: Over time, seals, O-rings, or the valve seat may wear out, causing irregular water flow.
- Blockages or Debris: Dirt, rust, or mineral buildup inside the valve can disrupt water flow and cause noise.
Step 2: Check and Adjust the Water Pressure
High water pressure is a common culprit behind noisy valves.
- Measure the Pressure: Use a pressure gauge to check your system’s water pressure. The ideal range is 40-60 psi.
- Adjust the Pressure: If the pressure is too high, locate your water pressure regulator (usually near the main water valve) and lower it to a safe level.
Step 3: Release Trapped Air from the System
If trapped air is causing the spitty sound, you can easily bleed it out:
- Turn Off the Main Water Supply: Shut off the main valve to your home.
- Open Faucets from Top to Bottom: Starting with the highest faucet (like one in an upstairs bathroom) and working your way down, open all faucets to let the water and air drain out.
- Turn the Water Back On Slowly: After the air is released, reopen the main valve slowly and let water run through all faucets until the noise disappears.
Step 4: Inspect and Clean the Valve
Sometimes the problem is within the valve itself.
- Shut Off the Valve’s Water Supply: Close the valve or the main water supply to the affected area.
- Disassemble the Valve: Remove the handle and loosen the packing nut to access the internal components.
- Inspect the Components: Check for worn O-rings, cracked seals, or mineral buildup.
- Replace or Clean: Replace any damaged parts and use a brush with vinegar or a descaling solution to clean away debris.
Step 5: Flush the Pipes and Valve
If debris or sediment is causing the noise:
- Remove the valve temporarily.
- Turn on the water supply to flush out the pipes and dislodge any blockages.
- Reinstall the valve and test for noise.
Step 6: Install a Water Hammer Arrestor (Optional)
If the spitty noise happens when turning the valve on or off, it could be water hammer (pressure surges). Installing a water hammer arrestor can absorb these surges and eliminate the noise.
Step 7: Prevent Future Problems
To keep your brass valves running smoothly:
- Regular Maintenance: Check valves periodically and clean them as needed.
- Control Water Pressure: Keep water pressure within a safe range to prevent damage.
- Choose Quality Valves: Use durable, high-quality brass valves like the ones from BORNIC to avoid common issues.
When to Call a Professional
If the spitty sound doesn’t go away after trying these fixes, there might be a deeper issue, such as improper pipe sizing or hidden damage. Don’t hesitate to contact a professional plumber for help.
